The 5A summarizes the activities that should be performed by healthcare personnel during the brief intervention with the patient to stop smoking and are: find out, advise, analyze, help, accompany or agree. Therefore, the one that is not included in the strategy would be option 2: increase.

A 42-year-old woman visits her family physician for gonalgia. Opportunistic use is made of the consultation to assess lifestyles, especially smoking. If you want to follow the health education strategy based on the five "a's" model, which of the following is NOT included in this strategy:

Inquire: ask about risk factors and risk behaviors (ask the patient if she smokes).

Increase: increase risk perception to facilitate change (explain the consequences of smoking).

Advise: give clear, specific and personalized advice (advise smoking cessation).

Agree: collaboratively agree on goals for change (assess readiness to make a quit attempt).

A population-based survey of physician smoking cessation counseling practices.

To be most effective, physicians' smoking cessation interventions must go beyond advice, to include counseling and follow-up. A full profile of physician performance on the recommended activities to promote smoking cessation has not been provided previously. We surveyed a representative sample of 246 community-based primary care physicians who had agreed to participate in a 3-year study to evaluate a strategy for disseminating smoking cessation interventions, based on the National Cancer Institute 4-A model and on the Transtheoretical Model of Change. A majority reported they Ask (67%) and Advise (74%) their patients about smoking, while few go beyond to Assist (35%) or Arrange follow-up (8%) with patients who smoke. The criteria for "thorough" counseling was met by only 27% of physicians. More than half were not intending to increase counseling activity in the next 6 months. After controlling for other variables, physicians in private offices were more likely than physicians in HMO or other settings to be active with smoking cessation counseling. General Internal Medicine physicians were most active, and Ob/Gyn physicians were least active, with smoking cessation counseling among primary care specialty groups. Innovative approaches are needed to motivate, support, and reward physicians to counsel their patients who smoke, especially when considering the movement toward managed health care. A survey of primary care physicians focusing on national guidelines for smoking cessation counseling showed a majority Ask (67%) and Advise (74%) patients about smoking, but few Assist (35%) or Arrange follow-up (8%).

Ask-Advise-Connect: a new approach to smoking treatment delivery in health care settings.

Several national health care-based smoking cessation initiatives have been recommended to facilitate the delivery of evidence-based treatments, such as quitline (telephone-based tobacco cessation services) assistance. The most notable examples are the 5 As (Ask, Advise, Assess, Assist, Arrange) and Ask. Advise. Refer. (AAR) programs. Unfortunately, rates of primary care referrals to quitlines are low, and most referred smokers fail to call for assistance. To evaluate a new approach--Ask-Advise-Connect (AAC)--designed to address barriers to linking smokers with treatment. A pair-matched, 2-treatment-arm, group-randomized design in 10 family practice clinics in a single metropolitan area. Five clinics were randomized to the AAC (intervention) and 5 to the AAR (control) conditions. In both conditions, clinic staff were trained to assess and record the smoking status of all patients at all visits in the electronic health record, and smokers were given brief advice to quit. In the AAC clinics, the names and telephone numbers of smokers who agreed to be connected were sent electronically to the quitline daily, and patients were called proactively by the quitline within 48 hours. In the AAR clinics, smokers were offered a quitline referral card and encouraged to call on their own. All data were collected from February 8 through December 27, 2011. Ten clinics in Houston, Texas. Smoking status assessments were completed for 42,277 patients; 2052 unique smokers were identified at AAC clinics, and 1611 smokers were identified at AAR clinics. Linking smokers with quitline-delivered treatment. Impact was based on the RE-AIM (Reach, Efficacy, Adoption, Implementation, and Maintenance) conceptual framework and defined as the proportion of all identified smokers who enrolled in treatment. In the AAC clinics, 7.8% of all identified smokers enrolled in treatment vs 0.6% in the AAR clinics (t4 = 9.19 [P < .001]; odds ratio, 11.60 [95% CI, 5.53-24.32]), a 13-fold increase in the proportion of smokers enrolling in treatment. The system changes implemented in the AAC approach could be adopted broadly by other health care systems and have tremendous potential to reduce tobacco-related morbidity and mortality.

Best practices for smoking cessation in pregnancy: do obstetrician/gynecologists use them in practice?

To assess Ohio obstetrician/gynecologists' perceptions and use of the 5As method of smoking cessation (ask, advise, assess, assist, and arrange) with pregnant patients who smoke. A three-wave mailing procedure was used with a statewide random sample of obstetrician/ gynecologists who responded to a valid and reliable 31-item questionnaire. Regarding the 5As method of smoking cessation, almost all (98%) asked their pregnant patients about smoking, but fewer respondents engaged in advising (66%), assessing (42%), assisting (29%), and arranging for follow-up visits or referrals (6%). Higher efficacy expectations were associated with greater use of the 5As method (r = 0.52, p < 0.001). A majority believed that two cessation activities would result in smoking cessation in pregnant smokers: explaining the dangers of smoking (65%) and referring pregnant smokers to smoking cessation programs (57%). However, 26% of physicians reported that they were "slightly confident" or "not confident at all" in their ability to refer pregnant smokers to such programs, and 6% of physicians reported always providing smoking cessation referrals. A significant proportion of respondents believed that prenatal smoking would not cause severe effects for the unborn child but would likely lead to moderate (46%) or minor (3%) health effects. Obstetrician/gynecologists face many competing demands for their time and energy, yet 62% believed smoking cessation advice would be of significant value. Physicians with higher levels of efficacy expectations reported significantly greater use of the 5 As. Future research should explore ways to facilitate obstetrician/gynecologists' use of the 5As method.

Assessment of compliance with U.S. Public Health Service clinical practice guideline for tobacco by primary care physicians.

The US Public Health Service clinical practice guideline treating tobacco use and dependence: 2008 update established an expanded standard of care, calling on physicians to consistently identify their patients who use tobacco and treat them using counseling and medication. To assess compliance, we examined the extent to which physicians self-report following four of the five components of the 5A model: Ask about tobacco use, Advise patients who use tobacco to quit, Assist the patient in making a quit attempt, and Arrange for follow-up care. We used data from a Web-based panel survey administered to a convenience sample of 1,253 primary care providers (family/general practitioners, internists, and obstetrician/gynecologists). We found that 97.1% of the providers reported that they consistently Asked and documented tobacco use, while 98.6% reported that they consistently Advised their patients to quit using tobacco. Among the family/general practitioners and internists, 98.3% recommended "any" (medication, counseling, counseling and medication, telephone quitline) smoking cessation strategies (Assist). Among all providers, 48.0% reported that they consistently scheduled a follow-up visit (Arrange). This study revealed that most primary care physicians reported that they Ask their patients about tobacco use, Advise them to quit, and Assist them in making a quit attempt, but only half reported that they Arrange a follow-up visit. Tobacco use screening and intervention are among the most effective clinical preventive services; thus, efforts to educate, encourage, and support primary care physicians to provide evidence-based treatments to their patients should be continued.

"Should I give you my smoking lecture now or later?" Characterizing emergency physician smoking discussions and cessation counseling.

We determine frequency and manner in which emergency physicians address smoking with their patients. This was a descriptive secondary analysis of 871 audiotapes of physician-patient interactions collected during a trial assessing the effect of computer-based health risk assessment on emergency physician-patient communication. Consenting nonemergency female patients, ages 18 to 65 years, were enrolled from 2 socioeconomically diverse academic emergency department (EDs) for audiotaping of the ED visit. All audio files with any mention of smoking were independently coded with an in-depth structured coding form to characterize the nature of smoking-related discussions. Logistic regression was used to determine factors associated with emergency physician screening and discussion of tobacco exposure with women patients. Overall, 484 of 871 (56%) participants were verbally screened for smoking, with 156 of 484 (32%) disclosing current smoking, with similar incidence at both sites. Tobacco screening was higher (odds ratio 2.2; 95% confidence interval 1.3 to 3.5), whereas rates of smoking-related discussions were lower (odds ratio 0.41; 95% confidence interval 0.17 to 0.98) at the urban site. At both sites, physicians tended to screen and discuss smoking when patients presented with a health condition that could be aggravated by smoking. Only 56% of discussions with current smokers contained advice to quit, 16% included assessment of readiness to quit, and a minority (13%) included a referral. Physician empathy/encouragement was associated with patients' detailing quit attempts. Emergency physicians were likely to gather information about smoking but not to counsel or advise patients to quit. These results raise the question of whether emergency medicine resident training should include additional emphasis on smoking cessation counseling and motivational interviewing techniques.

[A review of the evidence based smoking cessation interventions delivered by the family physician].

Smoking is one of the most preventable causes of morbidity and mortality resulting in almost 10,000 deaths each year in Israel. Since tobacco-related disease is preventable, efforts to promote cessation in patients who smoke should be a routine step in preventive primary care measures. In Israel, 26% of the adult population smoke. Within this group, a third want to quit but only two percent succeed in abstaining from smoking for a whole year. Family physicians are in an ideal position to facilitate patients' attempts to quit smoking: 70% of smoking patients report that firm, supportive messages from their family physician can act as an important motivating factor to quit smoking. The updated Clinical Practice Guidelines from the US Public Health Service recommend that family physicians should opportunistically advise smokers to stop smoking during routine consultation, encourage and assist smokers in the use of nicotine replacement therapies or bupropion and refer smokers to professional behavioral or psychological counselors specializing in smoking cessation. Most physicians rank smoking as the most important behavior affecting health, but few physicians are confident in their own ability to help their patients stop smoking. In this review the authors present several evidence-based strategies that were found to be helpful in promoting smoking cessation when delivered by general practitioners. The power of the physician's advice, first and second line agents, behavioral counseling and stage based interventions, are all discussed in detail.

Initiation of health behavior discussions during primary care outpatient visits.

Despite the importance of health promotion, rates of health behavior advice remain low and little is known about how advice is integrated into routine primary care. This study examines how health behavior topics of diet, physical activity and smoking are initiated during outpatient visits. Audio recording of 187 adults visit to five purposefully selected physicians. An iterative analysis involved listening to and discussing cases to identify emergent patterns of initiation of health behavior talk and advice that followed. Physicians initiated 65% of discussions and used two overarching strategies (1) Structured: a routine to ask about health behavior and (2) Opportunistic: use of a trigger to make a transition to talk about health behavior. Opportunistic strategies identified a greater proportion of patients at risk (50% vs. 34%) and led to a greater rate of advice (100% vs. 75%). Patients initiated one-third of health behavior discussions and were more likely to receive advice if they explicitly indicated readiness to change. Opportunistic strategies show promise for a higher yield of identifying patients at risk and leading to advice. Encouraging patients to be explicit about their readiness to change is likely to increase physician advice and assistance.

Delivering evidence-based smoking cessation treatment in primary care practice: experience of Ontario family health teams.

To report on the delivery of evidence-based smoking cessation treatments (EBSCTs) within a sample of 40 Ontario family health teams (FHTs). In each FHT, consecutive patients were screened for smoking status and eligible patients completed a questionnaire immediately following their clinic visits (index visits). Multilevel analysis was used to examine FHT-level, provider-level, and patient-level predictors of EBSCT delivery. Forty FHTs in Ontario. Across the 40 participating FHTs, 24,033 patients were screened and 2501 eligible patients contributed data. Provider performance in the delivery of EBSCTs during the preceding 12 months and during the index visits was assessed. The rate of provider delivery of EBSCT for the previous 12 months was 74.0% for the advise strategy. At the index visit, rates of EBSCT strategy delivery were 56.8% for ask; 46.9% for advise; 38.7% for assist; 11.6% for prescribing pharmacotherapy; and 11.3% for arrange follow-up. Significant intra-FHT and intraprovider variability in the rates of EBSCT delivery was identified. Family health teams with a physician champion (odds ratio [OR] 2.0; 95% CI 1.1 to 3.6; P < .01) and providers who highly ranked the importance of smoking cessation (OR 1.7; 95% CI 1.1 to 2.7; P < .01) were more likely to deliver EBSCTs. Patient readiness to quit (OR 1.6; 95% CI 1.3 to 1.9; P < .001), presence of smoking-related illness (OR 1.6; 95% CI 1.2 to 2.1; P < .01), and presenting for an annual health examination (OR 2.0; 95% CI 1.6 to 2.5; P < .001) were associated with the delivery of EBSCTs. Rates of smoking cessation advice were higher than previously reported for Canadian physicians; however, rates of assistance with quitting were lower. Future quality improvement initiatives should specifically target increasing the rates of screening and advising among low-performing FHTs and providers within FHTs, with a particular emphasis on doing so at all clinic appointments; and improving the rate at which assistance with quitting is delivered.

Tobacco use screening and counseling during physician office visits among adults--National Ambulatory Medical Care Survey and National Health Interview Survey, United States, 2005-2009.

Tobacco use continues to be the leading cause of preventable disease and death in the United States; cigarette smoking accounts for approximately 443,000 premature deaths annually. In 2009, the prevalence of smoking among U.S. adults was 20.6% (46 million smokers), with no significant change since 2005 (20.9%). In 2010, approximately 69% of smokers in the United States reported that they wanted to quit smoking. Approximately 44% reported that they tried to quit in the past year for ≥1 day; however, only 4%-7% were successful each year. Tobacco dependence has many features of a chronic disease: most patients do not achieve abstinence after their first attempt to quit, they have periods of relapse, and they often require repeated cessation interventions. At least 70% of smokers visit a physician each year, and other smokers visit other health-care professionals, providing key opportunities for intervention. The 2008 update to the U.S. Public Health Service (PHS) Clinical Practice Guideline: Treating Tobacco Use and Dependence recommends that clinicians and health-care delivery systems consistently identify and document tobacco use status and treat every tobacco user seen in a health-care setting using the 5 A's model: 1) ask about tobacco use, 2) advise tobacco users to quit, 3) assess willingness to make a quit attempt, 4) assist in quit attempt, and 5) arrange for follow-up. The PHS guideline also recommends the following as effective methods for increasing successful cessation attempts: individual, group, and telephone counseling; any of the seven first-line medications for tobacco dependence that are approved by the Food and Drug Administration (FDA); and provision of coverage for these treatments by health-care systems, insurers, and purchasers. However, clinicians and health-care systems often do not screen for and treat tobacco use consistently and effectively.

Smoking cessation

Dental professionals also provide a key component in increasing tobacco abstinence rates in the community through counseling patients on the effects of tobacco on oral health in conjunction with an oral exam. According to the 2008 Guideline, based on two studies the training of clinicians in smoking cessation methods may increase abstinence rates; however, a Cochrane review found and measured that such training decreased smoking in patients. Reducing or eliminating the costs of cessation therapies for smokers increased quit rates in three meta-analyses. In one systematic review and meta-analysis, multi-component interventions increased quit rates in primary care settings. "Multi-component" interventions were defined as those that combined two or more of the following strategies known as the "5 A's": Ask — Systematically identify all tobacco users at every visit Advise — Strongly urge all tobacco users to quit Assess — Determine willingness to make a quit attempt

Smoking Cessation -- Introduction

Assisting patients with smoking cessation is one of the most important primary care tasks, and the benefits of assessing patients’ smoking behavior are well established. The US Preventive Services Task Force (USPSTF) recommends using the 5 As: Ask about smoking Office systems should ensure that smoking status is documented at every visit. Advise to quit Use clear, personalized messages.  Even brief advice from a physician can improve quit rates compared with patients who receive no advice. Assess willingness to quit Patients assessed as not yet willing to quit should receive the motivational intervention. Assist in quitting Ask patients who are willing to set a quit date. Arrange follow-up and support

Do doctors' smoking habits influence their smoking cessation practices? A systematic review and meta-analysis.

To assess the association between doctors' smoking status and the use of the '5As' of smoking cessation. A systematic search of 11 databases covering English and Spanish language publications since 1996 was undertaken. Studies were included if they reported doctors' smoking status (current, former or never smoker) and rates of practising any of the 5As of smoking cessation (Ask; Advise; Assess; Assist; and Arrange). Frequencies and proportions were extracted from individual papers and risk ratios (RR) were calculated. A random-effects meta-analysis model was used to assess the effect of the doctor's personal smoking history. Covariate effects were explored using meta-regression for three pre-specified study characteristics: doctors' role, smoking prevalence of the sample and study quality. Twenty studies were included in this systematic review. The RR of always asking patients about their smoking was not associated significantly with doctors' smoking status [RR = 0.98; 95% confidence interval (CI) = 0.94-1.02; P = 0.378; I(2)  = 0.00%; 10 studies]. Meta-analysis suggested that doctors who were current smokers had a 17% increased risk of not advising their patients to quit compared with never-smokers (RR = 0.83; 95% CI = 0.77-0.90; P < 0.000; I(2)  = 82.14%; 14 studies). However, high levels of heterogeneity were found that were not explained by the meta-regression. Regarding assisting patients to quit, never smokers were more likely to counsel than current smokers (RR = 0.92; 95% CI = 0.85-0.99; P = 0.036; I(2)  = 0.00%; three studies) but less likely to make a referral (RR = 1.40; 95% CI = 1.09-1.79; P = 0.009; I(2)  = 0.00%; five studies). No statistically significant differences were found in arranging future contact by smoking status (RR = 0.80; 95% CI = 0.52-1.23; P = 0.315; I(2)  = 47.03%; four studies). Smoking status of doctors may affect their delivery of smoking cessation treatments to patients, with smokers being less likely than non-smokers or ex-smokers to advise and counsel their patients to quit but more likely to refer them to smoking cessation programmes.

How do residents prioritize smoking cessation for young "high-risk" women? Factors associated with addressing smoking cessation.

Sixty-seven percent of physicians report advising their smoking patients to quit. Primary care residents' priorities for preventive health for a young "high-risk" female are unknown. Factors related to residents addressing smoking also need examining. One hundred residents completed a survey about preventive health issues for a woman in her 20s "who leads a high-risk lifestyle." Residents indicated which topics they would address, and the likelihood that they would address each of 12 relevant preventive health topics, their outcome expectancies that the patient would follow their advice on each topic, their confidence that they could address the topic, and perceived barriers for addressing the topic. Residents listed STD prevention most frequently. Drug use and smoking cessation were second and third most frequently listed. Residents who believed that the patient would follow their advice were more likely to list smoking cessation than residents who had lower outcome expectancies for that patient. Higher barriers were negatively related to addressing smoking cessation. When time is not a barrier, residents are likely to address smoking cessation. Teaching residents how to incorporate this subject into their clinical practice is needed. Raising residents' outcome expectancies may increase their likelihood of addressing smoking cessation.

Realistic approaches to counseling in the office setting.

Although it is often unrecognized, family physicians provide a significant amount of mental health care in the United States. Time is one of the major obstacles to providing counseling in primary care. Counseling approaches developed specifically for ambulatory patients and traditional psychotherapies modified for primary care are efficient first-line treatments. For some clinical conditions, providing individualized feedback alone leads to improvement. The five A's (ask, advise, assess, assist, arrange) and FRAMES (feedback about personal risk, responsibility of patient, advice to change, menu of strategies, empathetic style, promote self-efficacy) techniques are stepwise protocols that are effective for smoking cessation and reducing excessive alcohol consumption. These models can be adapted to address other problems, such as treatment nonadherence. Although both approaches are helpful to patients who are ready to change, they are less likely to be successful in patients who are ambivalent or who have broader psychosocial problems. For patients who are less committed to changing health risk behavior or increasing healthy behavior, the stages-of-change approach and motivational interviewing address barriers. Patients with psychiatric conditions and acute psychosocial stressors will likely respond to problem-solving therapy or the BATHE (background, affect, troubles, handling, empathy) technique. Although brief primary care counseling has been effective, patients who do not fully respond to the initial intervention should receive multimodal therapy or be referred to a mental health professional.

Reducing pediatric exposure to environmental tobacco smoke: The effects of pediatric exposure to environmental tobacco smoke and the role of pediatric perioperative care.

Exposure to environmental tobacco smoke (ETS) has deleterious effects on a child's general health and their perioperative risk; specifically, it doubles a child's perioperative risk of adverse respiratory events, particularly laryngospasm. It increases the risk of sudden infant death syndrome, bacterial meningitis, middle ear infection, asthma, and lower respiratory tract infection. The preoperative assessment of children presenting for procedures under general anesthesia is an opportune moment to screen for exposure to ETS and give information about the risks and cessation support (if applicable). This can be described as a "teachable moment"; there is a documented need for this public health education and it aligns with the NHS Long Term Plan, aiming to embed public health information into every consultation a patient or family has with a healthcare practitioner. The period preceding and following surgery is a time when patients or their families are motivated to make a behavioral change. It has been shown that parents who smoke are more likely to attempt smoking cessation if their child has had recent surgery but not to maintain their abstinence; however, we know that subsequent quit attempts increase the likelihood that a smoker will succeed in permanently abstaining so aiming for a quit attempt rather than permanent abstinence is a valid aim. A suggested screening method would be to firstly ask all parents or carers in the preoperative health screening questionnaire about their child's exposure to ETS, accepting this lacks both the sensitivity and specificity of a valid screening tool. This can be augmented by measuring exhaled carbon monoxide in any child who is able to comply with the test; exhaled carbon monoxide has been shown to be a valid screening tool for exposure to ETS in adolescents but not children under 12 years of age, perhaps because smaller children may not be able to cooperate with the test which requires a vital capacity maneuver to provide an adequate endtidal sample. A suggested model for smoking cessation intervention is called Very Brief Advice and comprises three parts: Ask about a child's exposure to ETS with/without exhaled carbon monoxide measurement Advise about the risks to the child's general and perioperative health and the health of the smoker and wider family plus the benefits of smoking cessation Act on the response by referring to local smoking cessation support. Referral to local smoking cessation services should be along established pathways. Thus, recording a household smoking status and referring to local smoking cessation services targets a public health measure with benefits beyond the individual patient and planned anesthetic. There is no evidence in the literature of the effect of environmental exposure to electronic cigarettes ("vaping") on a child's perioperative health. Further research is needed to establish if preoperative reduction in or removal from exposure to ETS reduces the risk of respiratory adverse events in the child.

Promoting smoking cessation.

Cigarette smoking causes significant morbidity and mortality in the United States. Physicians can use the five A's framework (ask, advise, assess, assist, arrange) to promote smoking cessation. All patients should be asked about tobacco use and assessed for motivation to quit at every clinical encounter. Physicians should strongly advise patients to quit smoking, and use motivational interviewing techniques for patients who are not yet willing to stop smoking. Clinical contacts with unmotivated patients should emphasize the rewards and relevance of quitting, as well as the risks of smoking and anticipated barriers to abstinence. These messages should be repeated at every opportunity. Appropriate patients should be offered pharmacologic assistance in quitting, such as nicotine replacement therapies, bupropion, and varenicline. Use of pharmacologic support during smoking cessation can double the rate of successful abstinence. Using more than one type of nicotine replacement therapy ("patch plus" method) and combining these therapies with bupropion provide additional benefit. However, special populations pose unique challenges in pharmacotherapy for smoking cessation. Nicotine replacement therapies increase the risk of birth defects and should not be used during pregnancy. They are usually safe in patients with cardiovascular conditions, except for those with unstable angina or within two weeks of a coronary event. Varenicline may increase the risk of coronary events. Nicotine replacement therapies are safe for use in adolescents; however, they are less effective than in adults. Physicians also should arrange to have repeated contact with smokers around their quit date to reinforce cessation messages.

Randomized controlled trial of a computer-based, tailored intervention to increase smoking cessation counseling by primary care physicians.

The primary care visit represents an important venue for intervening with a large population of smokers. However, physician adherence to the Smoking Cessation Clinical Guideline (5As) remains low. We evaluated the effectiveness of a computer-tailored intervention designed to increase smoking cessation counseling by primary care physicians. Physicians and their patients were randomized to either intervention or control conditions. In addition to brief smoking cessation training, intervention physicians and patients received a one-page report that characterized the patients' smoking habit and history and offered tailored recommendations. Physician performance of the 5As was assessed via patient exit interviews. Quit rates and smoking behaviors were assessed 6 months postintervention via patient phone interviews. Intervention effects were tested in a sample of 70 physicians and 518 of their patients. Results were analyzed via generalized and mixed linear modeling controlling for clustering. Intervention physicians exceeded controls on "Assess" (OR 5.06; 95% CI 3.22, 7.95), "Advise" (OR 2.79; 95% CI 1.70, 4.59), "Assist-set goals" (OR 4.31; 95% CI 2.59, 7.16), "Assist-provide written materials" (OR 5.14; 95% CI 2.60, 10.14), "Assist-provide referral" (OR 6.48; 95% CI 3.11, 13.49), "Assist-discuss medication" (OR 4.72;95% CI 2.90, 7.68), and "Arrange" (OR 8.14; 95% CI 3.98, 16.68), all p values being < 0.0001. Intervention patients were 1.77 (CI 0.94, 3.34,p = 0.078) times more likely than controls to be abstinent (12 versus 8%), a difference that approached, but did not reach statistical significance, and surpassed controls on number of days quit (18.4 versus 12.2, p < .05) but not on number of quit attempts. The use of a brief computer-tailored report improved physicians' implementation of the 5As and had a modest effect on patients' smoking behaviors 6 months postintervention.

Strategies to improve smoking cessation rates in primary care.

Primary care is an important setting in which to treat tobacco addiction. However, the rates at which providers address smoking cessation and the success of that support vary. Strategies can be implemented to improve and increase the delivery of smoking cessation support (e.g. through provider training), and to increase the amount and breadth of support given to people who smoke (e.g. through additional counseling or tailored printed materials). To assess the effectiveness of strategies intended to increase the success of smoking cessation interventions in primary care settings. To assess whether any effect that these interventions have on smoking cessation may be due to increased implementation by healthcare providers. We searched the Cochrane Tobacco Addiction Group's Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and trial registries to 10 September 2020. We included randomized controlled trials (RCTs) and cluster-RCTs (cRCTs) carried out in primary care, including non-pregnant adults. Studies investigated a strategy or strategies to improve the implementation or success of smoking cessation treatment in primary care. These strategies could include interventions designed to increase or enhance the quality of existing support, or smoking cessation interventions offered in addition to standard care (adjunctive interventions). Intervention strategies had to be tested in addition to and in comparison with standard care, or in addition to other active intervention strategies if the effect of an individual strategy could be isolated. Standard care typically incorporates physician-delivered brief behavioral support, and an offer of smoking cessation medication, but differs across studies. Studies had to measure smoking abstinence at six months' follow-up or longer. We followed standard Cochrane methods. Our primary outcome - smoking abstinence - was measured using the most rigorous intention-to-treat definition available. We also extracted outcome data for quit attempts, and the following markers of healthcare provider performance: asking about smoking status; advising on cessation; assessment of participant readiness to quit; assisting with cessation; arranging follow-up for smoking participants. Where more than one study investigated the same strategy or set of strategies, and measured the same outcome, we conducted meta-analyses using Mantel-Haenszel random-effects methods to generate pooled risk ratios (RRs) and 95% confidence intervals (CIs). We included 81 RCTs and cRCTs, involving 112,159 participants. Fourteen were rated at low risk of bias, 44 at high risk, and the remainder at unclear risk. We identified moderate-certainty evidence, limited by inconsistency, that the provision of adjunctive counseling by a health professional other than the physician (RR 1.31, 95% CI 1.10 to 1.55; I<sup2</sup = 44%; 22 studies, 18,150 participants), and provision of cost-free medications (RR 1.36, 95% CI 1.05 to 1.76; I<sup2</sup = 63%; 10 studies,7560 participants) increased smoking quit rates in primary care. There was also moderate-certainty evidence, limited by risk of bias, that the addition of tailored print materials to standard smoking cessation treatment increased the number of people who had successfully stopped smoking at six months' follow-up or more (RR 1.29, 95% CI 1.04 to 1.59; I<sup2</sup = 37%; 6 studies, 15,978 participants). There was no clear evidence that providing participants who smoked with biomedical risk feedback increased their likelihood of quitting (RR 1.07, 95% CI 0.81 to 1.41; I<sup2</sup = 40%; 7 studies, 3491 participants), or that provider smoking cessation training (RR 1.10, 95% CI 0.85 to 1.41; I<sup2</sup = 66%; 7 studies, 13,685 participants) or provider incentives (RR 1.14, 95% CI 0.97 to 1.34; I<sup2</sup = 0%; 2 studies, 2454 participants) increased smoking abstinence rates. However, in assessing the former two strategies we judged the evidence to be of low certainty and in assessing the latter strategies it was of very low certainty. We downgraded the evidence due to imprecision, inconsistency and risk of bias across these comparisons. There was some indication that provider training increased the delivery of smoking cessation support, along with the provision of adjunctive counseling and cost-free medications. However, our secondary outcomes were not measured consistently, and in many cases analyses were subject to substantial statistical heterogeneity, imprecision, or both, making it difficult to draw conclusions. Thirty-four studies investigated multicomponent interventions to improve smoking cessation rates. There was substantial variation in the combinations of strategies tested, and the resulting individual study effect estimates, precluding meta-analyses in most cases. Meta-analyses provided some evidence that adjunctive counseling combined with either cost-free medications or provider training enhanced quit rates when compared with standard care alone. However, analyses were limited by small numbers of events, high statistical heterogeneity, and studies at high risk of bias. Analyses looking at the effects of combining provider training with flow sheets to aid physician decision-making, and with outreach facilitation, found no clear evidence that these combinations increased quit rates; however, analyses were limited by imprecision, and there was some indication that these approaches did improve some forms of provider implementation. There is moderate-certainty evidence that providing adjunctive counseling by an allied health professional, cost-free smoking cessation medications, and tailored printed materials as part of smoking cessation support in primary care can increase the number of people who achieve smoking cessation. There is no clear evidence that providing participants with biomedical risk feedback, or primary care providers with training or incentives to provide smoking cessation support enhance quit rates. However, we rated this evidence as of low or very low certainty, and so conclusions are likely to change as further evidence becomes available. Most of the studies in this review evaluated smoking cessation interventions that had already been extensively tested in the general population. Further studies should assess strategies designed to optimize the delivery of those interventions already known to be effective within the primary care setting. Such studies should be cluster-randomized to account for the implications of implementation in this particular setting. Due to substantial variation between studies in this review, identifying optimal characteristics of multicomponent interventions to improve the delivery of smoking cessation treatment was challenging. Future research could use component network meta-analysis to investigate this further.

A pilot study on inducement of smoking cessation by a simple 5A (asking, advice, assess, assist, and arrange) approach at outpatient clinics.

Asking smokers about their smoking status, followed by advice to quit smoking, assessing the intention to quit, assistance with cessation, and arrange of follow-up (5A) is recommended for induction of smoking cessation. To obtain preliminary data on effects of "5A" , we investigated the smoking cessation rate with two modes in the phase I: 1) self-administered questionnaire and 2) doctor's interview at respiratory disease clinics of three general hospitals in Japan, and another mode in phase II: 3) doctor's interview with an additional pamphlet at one of the three hospitals. The interviews for smokers were conducted by doctors in charge of treatment. Subject smoking habits were followed up by postal surveys three months after the enrollment. In phase I, 359 outpatients were recruited and 189 smokers responded, among whom 27 patients (7.5% of 359 outpatients) had quit smoking at the three months after the enrollment. The cessation rate of the self-administered questionnaire group (8.4% of 238 smokers) did not differ significantly from that of doctors' interview group (5.8% of 121 smokers). Age and intention to quit at enrollment were found to be independent predictors of smoking cessation. Patients aged 50 years or older (odds ratio=5.05, 95% confidence interval 1.89-13.54), and participants with an intention to quit (odds ratio=6.78, 95% confidence interval 2.66-17.30) were more likely to be successful in quitting. In phase II, another 212 smokers of one hospital were interviewed by doctors in charge and provided with an additional pamphlet describing how to practice to dislike smoking. No significant difference in the cessation rate was observed between phase I and phase II (5.8% vs. 8.0%). In conclusion, there were no differences among the three modes of "5A", but 7.7% of the 571 outpatients visiting respiratory divisions quit smoking with this simple "5A". The findings may indicate that this simple practice at clinics is useful for smoking cessation strategy, although randomized trials are now required.

Chinese physicians and their smoking knowledge, attitudes, and practices.

China has the most smokers among the world's nations. Physicians play a key role in smoking cessation, but little is known about Chinese physicians and smoking. This 2004 clustered randomized survey of 3552 hospital-based physicians from six Chinese cities measured smoking attitudes, knowledge, personal behavior, and cessation practices for patients. Descriptive statistics and multivariate analysis of factors associated with asking about or advising against smoking were conducted in 2005 and 2006. Smoking prevalence was 23% among all Chinese physicians, 41% for men and 1% for women. Only 30% report good implementation of smoke-free workplace policies and 37% of current smokers have smoked in front of their patients. Although 64% usually advise smokers to quit, only 48% usually ask about smoking status, and 29% believe most smokers will follow their cessation advice. Less than 7% set quit dates or use pharmacotherapy when helping smokers quit. Although 95% and 89%, respectively, know that active or passive smoking causes lung cancer, only 66% and 53%, respectively, know that active or passive smoking causes heart disease. Physicians were significantly more likely to ask about or advise against smoking if they believed that counseling about health harms helps smokers quit and that most smokers would follow smoking-cessation advice. Physician smoking cessation, smoke-free workplaces, and education on smoking-cessation techniques need to be increased among Chinese physicians. Strengthening counseling skills may result in more Chinese physicians helping smoking patients to quit. These improvements can help reduce the Chinese and worldwide health burden from smoking.

[Practitioners confronted with the four main health behavioral risk factors].

Four behavioural risk factors are common in primary care and are often clustered in individuals. Smoking is present from I cigarette per day, excessive alcohol use is defined either by drinking regularly more than 2-3 standard glasses per day or by occasional heavy drinking of more than 4-5 glasses at a time. Patients who don't have regular moderate physical activity of at least 30 minutes during 5 days of a week or intensive physical activity of at least 20 minutes 3 times a week are sedentary. A Body Mass Index of over 30 defines obesity. We propose a "generic" counselling tool in 5 steps, the 5 As, that can be used for any of the four behavioural risk factors during routine consultations. With this counselling guide, practitioners can help patients change behaviour in a motivational style that allows shared decision-making.

Determinants of smoking and cessation in older women.

although the benefits of quitting smoking even at an advanced age have been proved, few campaigns target the older population. The goals of this study were to analyse the characteristics of older women smokers help and support those wanting to quit. we assessed the determinants of smoking cessation in a prospective cohort study performed in 7,609 older women. A questionnaire about smoking habits was sent to the 486 eligible smokers. Smoking dependence and smokers' readiness to quit was assessed. Participants who had quit smoking during follow-up were asked about their previous reasons for quitting and the methods used to quit. 372 women of the 424 (88%) responded to our questionnaire and were included. The most common reasons for smoking were relaxation, pleasure, and habit. Major obstacles to quitting smoking were 'no benefit to quitting at an advanced age', 'smoking few or "light" cigarettes yields no negative health consequences', and 'smoking does not increase osteoporotic risk'. During the 3-year follow-up period, 57 of the 372 (15%) women successfully quit smoking. Being an occasional smoker (OR=2.4) and reporting 'quitting is not difficult' (OR=3.7) were positively associated with having recently quit smoking. Only 11% of successful cessations were reported to have received physician advice. these data illustrate the specific smoking behaviour of older women, suggesting that cessation interventions ought to be tailored to these characteristics. Willingness to quit was associated with a low education level. The most frequent obstacles to quitting were all based on incorrect information.

Are obstetricians following best-practice guidelines for addressing pregnancy smoking? Results from northeast Tennessee.

In 2000, the American College of Obstetricians/Gynecologists(ACOG) established the 5 A's method of brief smoking cessation counseling (ask, advise, assess, assist, arrange) as a standard component of prenatal care. The purpose of this study was to describe use of the 5 A's in prenatal care in Northeast Tennessee, where pregnancy smoking rates are three times the national average, and to evaluate provider attitudes toward addressing pregnancy smoking. Surveys were distributed to all obstetric practices in a6-county area. One-quarter of respondents indicated they always asked pregnant patients about smoking, with two-thirds always giving their pregnant smokers advice to quit. Over half reported always assessing willingness to quit, while one-quarter or fewer always provided quit assistance, or arranged follow up. Over half believed addressing smoking was of significant value. Secondhand smoke was infrequently addressed. Demographics, efficacy, and outcome beliefs predicted use of the 5 A's. Most obstetric providers in Northeast Tennessee are not following ACOG recommendations for pregnancy smoking. Efforts to address pregnancy smoking and associated adverse pregnancy outcomes in the region should include facilitation of smoking cessation interventions in prenatal care.

InternalMed_Harrison

The process of stopping smoking is commonly a cyclical one, with the smoker sometimes making multiple attempts to quit and failing before finally being successful. Approximately 70–80% of smokers would like to quit smoking. More than one-half of current smokers attempted to quit in the last year, but only 6% quit for 6 months, and only 3% remain abstinent for 2 years. Clinician-based smoking interventions should repeatedly encourage smokers to try to quit and to use different forms of cessation assistance with each new cessation attempt rather than focusing exclusively on immediate cessation at the time of the first visit. Advice from a physician to quit smoking, particularly at the time of an acute illness, is a powerful trigger for cessation attempts, with up to half of patients who are advised to quit making a cessation effort. Other triggers include the cost of cigarettes, media campaigns, and changes in rules to restrict smoking in the workplace.

Don't give up on it: Smoking cessation.

The aim of this Learning Unit is to give you the facts about smoking in order to enhance your assessment of your clients' health risks and the benefits they are likely to gain from stopping smoking, and to target intervention appropriately to help them stop.

Preconception Counseling -- Issues of Concern -- Substance Use and Smoking Cessation

Tobacco use is associated with preterm labor, fetal growth restriction, low birth weight, and placental abruption. Smoking cessation can reduce perinatal mortality and low birth weight by at least 20%. Smoking cessation counseling should be offered to the woman and her partner before and during early pregnancy. Women should be counseled that secondhand smoke can also impact the child's health after birth, including increased risks for asthma and childhood obesity. Healthcare providers can provide structured counseling, for example, using the 5A's intervention, which includes: Asking about tobacco use Advising patients quit Assessing willingness to quit Assisting patients with quitting through appropriate medications, counseling, referrals, and support groups. Arrange follow-up and support [1]

The Physician-Delivered Smoking Intervention Project: factors that determine how much the physician intervenes with smokers.

To determine factors that affect how much physicians trained to use a patient-centered smoking intervention intervene with their smoking patients. Forty internal medicine residents and ten internal medicine attending physicians trained in a patient-centered counseling approach were randomized to an algorithm condition (provision of intervention algorithm at each patient visit) or a no-algorithm condition. Smoking intervention steps used by physicians with patients were assessed with Patient Exit Interviews (PEIs). Ambulatory clinic; academic medical center. Five hundred twenty-seven adult smokers seen in clinic between June 1990 and April 1992. There was no difference in overall PEI scores or in individual PEI steps taken between the algorithm and no-algorithm conditions. Two patient baseline factors (reporting thinking of stopping smoking within six months and higher Fagerstrom Tolerance Score) and one physician factor (older age) were significantly predictive of higher PEI score. Provision of an intervention algorithm at each patient visit does not increase the likelihood that trained physicians who are cued to intervene will perform more of the intervention steps taught. Trained physicians are more likely to intervene with smokers who are more nicotine-dependent and who expect and desire to stop smoking.

[Mid-term evaluation of a help program for smokers].

Medical counsel to smokers is an intervention that has proved useful to motivate smokers to stop smoking. This study pretends evaluate the long-term impact (2 years and 9 months) of systematic and structured health counsel on the smoke habit from the primary health care. In April 1990, in four primary care centers from Barcelona and Zaragoza, Spain, a program of systematic counselling to stop smoking with an offer of subsequent follow-up was initiated in all adult smokers (15-65 years of age). According to the answer, every patient was classified on one of seven established categories that allowed a individualized follow-up. Data from the total population included in the program from the beginning till January 1993, are analyzed. From 683 known smokers (59.2% males and 40.8% women), 20 were excluded for different reasons and 343 were included in the program (56.4% cover). Average age of included smokers was 35.1 years (SE = 0.6) and average number of visits of 5.3 (SE = 0.2) which was significantly higher than those not included in the program (33.4; SE = 0.6, and 2.7; SE = 0.1). An average follow-up of 14.3 months (SE = 0.5) and of 2.6 (SE = 0.1) interventions on each individual were done. The average daily number of cigarettes was 18.4 (SE = 0.6) in the initial period and 13.3 (SE = 0.6) on the last program evaluation. The final answers showed a 18.1% of quitters and a decrease of more than 50% on the initial consume on 32.6%. In 12% the answer was negative. Programs of systematic help for smokers show a higher level of favourable responses than does normal counselling.

Smoking and HIV: what are the risks and what harm reduction strategies do we have at our disposal?

The World Health Organization estimates that smoking poses one of the greatest global health risks in the general population. Rates of current smoking among people living with HIV (PLHIV) are 2-3 times that of the general population, which contributes to the higher incidence of non-AIDS-related morbidity and mortality in PLHIV. Given the benefit of smoking cessation, strategies to assist individuals who smoke to quit should be a primary focus in modern HIV care. Tobacco harm reduction focuses on reducing health risk without necessarily requiring abstinence. However, there remains uncertainty about the safety, policy and familiarity of specific approaches, particularly the use of vaporised nicotine products. Evidence suggests that vaporised nicotine products may help smokers stop smoking and are not associated with any serious side-effects. However, there is the need for further safety and efficacy data surrounding interventions to assist quitting in the general population, as well as in PLHIV specifically. In addition, official support for vaping as a harm reduction strategy varies by jurisdiction and this determines whether medical practitioners can prescribe vaporised products and whether patients can access vaporised nicotine products. When caring for PLHIV who smoke, healthcare workers should follow general guidelines to assist with smoking cessation. These include: asking the patient about their smoking status; assessing the patient's readiness to quit and their nicotine dependence; advising the patient to stop smoking; assisting the patient in their attempt to stop smoking through referral, counselling, pharmacotherapy, self-help resources and/or health education; and arranging follow-up with the patient to evaluate their progress.

Do the five A's work when physicians counsel about weight loss?

More than two thirds of Americans are overweight or obese. Physician counseling may help patients lose weight; however, physicians perceive these discussions as somewhat futile and time-consuming. An effective and efficient tool for smoking cessation is the Five A's (Ask, Advise, Assess, Assist, and Arrange). We studied the effectiveness of the Five A's in weight-loss counseling. We audiorecorded primary care encounters between 40 physicians and 461 of their overweight or obese patients. All were told the study was about preventive health, not weight specifically. Encounters were coded for physician use of the Five A's. Patients' motivation and confidence were assessed before and immediately after the encounter. Three months later, we assessed patient change in dietary fat intake, exercise, and weight. Generalized linear models were fit adjusting for patient clustering within physician. Physicians used at least one of the Five A's often (83%). Physicians routinely Ask and Advise patients to lose weight; however, they rarely Assess, Assist, or Arrange. Assist and Arrange were related to diet improvement, whereas Advise was associated with increases in motivation and confidence to change dietary fat intake and confidence to lose weight. Similar to smoking cessation counseling, physicians routinely Asked and Advised patients to lose weight; however, they rarely Assessed, Assisted, or Arranged. Given the potential impact of using all of these counseling tools on changing patient behavior, physicians should be encouraged to increase their use of the Five A's when counseling patients to lose weight.


The fourth noise usually appears when there is a certain degree of valvular stenosis.

65-year-old patient presenting progressive dyspnea of 5 days of evolution until becoming resting, three-pillow orthopnea and episodes of paroxysmal nocturnal dyspnea. Auscultation highlights bilateral crackles, holosystolic murmur radiating to the axilla and gallop rhythm for the third and fourth sounds. Mark the CORRECT statement:

The third noise coincides with the rapid filling phase of the ventricular diastole of the cardiac cycle.

The most likely diagnosis is heart failure.

The holosystolic murmur may correspond to mitral insufficiency.

Valvular heart disease

Medical signs of aortic stenosis include pulsus parvus et tardus, that is, diminished and delayed carotid pulse, fourth heart sound, decreased A2 sound, sustained apex beat, precordial thrill. Auscultation may reveal a systolic murmur of a harsh crescendo-decrescendo type, heard in 2nd right intercostal space and radiating to the carotid arteries. Aortic regurgitation Patients with aortic regurgitation may experience heart failure symptoms, such as dyspnea on exertion, orthopnea and paroxysmal nocturnal dyspnea, palpitations, and angina pectoris. In acute cases patients may experience cyanosis and circulatory shock.

Cardiac examination

Finally the sacrum and ankles are checked for pitting edema which is caused by right ventricular failure in isolation or as part of congestive cardiac failure. Auscultation One should comment on S1 and S2 – if the splitting is abnormal or louder than usual. S3 – the emphasis and timing of the syllables in the word Kentucky is similar to the pattern of sounds in a precordial S3. S4 – the emphasis and timing of the syllables in the word Tennessee is similar to the pattern of sounds in a precordial S4. If S4 S1 S2 S3 Also known as a gallop rhythm. diastolic murmurs (e.g. aortic regurgitation, mitral stenosis) systolic murmurs (e.g. aortic stenosis, mitral regurgitation) pericardial rub (suggestive of pericarditis) The base of the lungs should be auscultated for signs of pulmonary oedema due to a cardiac cause such as bilateral basal crepitations.

Ultimate Third Heart Sound.

A 79-year-old man with dilated cardiomyopathy and severe functional mitral regurgitation presented with general fatigue and dyspnea. Auscultation revealed a systolic regurgitant murmur with a minimized second heart sound due to a low output. On the other hand, the third heart sound was ultimately enhanced, being visible and palpable as a pulsatile knock of the precordium. Phonocardiography and echocardiography successfully confirmed early-diastolic rapid distension of the left ventricle along with rapid ventricular filling and abrupt deceleration of the atrioventricular blood flow to be the precise etiology of the ultimate third heart sound, indicating critically deteriorated hemodynamics due to massive mitral regurgitation combined with a low output.

Third heart sound

It has also been termed a ventricular gallop or a protodiastolic gallop because of its place in early diastole. It is a type of gallop rhythm by virtue of having an extra sound; the other gallop rhythm is called S4. The two are quite different, but they may sometimes occur together forming a quadruple gallop. If the heart rate is also very fast (tachycardia), it can become difficult to distinguish between S3 and S4 thus producing a single sound called a summation gallop. S3 is a dull, low-pitched sound best heard with the bell placed over the cardiac apex with the patient lying in the left lateral decubitus position. This heart sound when present in a child or young adult implies the presence of a supple ventricle that can undergo rapid filling. Conversely, when heard in a middle-aged or older adult, an S3 is often a sign of disease, indicating increased ventricular filling due to congestive heart failure or severe mitral or tricuspid regurgitation.

Cardiac pearls.

Most diagnoses of cardiovascular disease are made in the office or at the bedside. For example, in pulsus alternans of the radial pulse, observed when first greeting a patient, alteration of intensity of the second sound and systolic murmur and a ventricular (S3) gallop are clinical pearls--often subtle--that diagnose cardiac decompensation. A faint gallop, ventricular (S3) or atrial (S4), might be overlooked in a patient who has an emphysematous chest and an increase in anteroposterior diameter if one listens over the usual areas of the precordium. However, the gallop might be detected easily by listening over the xiphoid or epigastric area. How do you tell the difference between an S4, a split first sound, and an ejection sound? The S4 is eliminated with pressure on the stethoscope, but pressure does not eliminate the ejection sound or the splitting of S1. The atrial sound (S4) is most frequently found in patients who have coronary heart disease, and it is a constant finding in patients who have hypertension. It does not denote heart failure, as does the S3 (ventricular) gallop. In some patients, both atrial (S4) and ventricular (S3) diastolic gallops may be present. This occurrence is common in patients with cardiac decompensation associated with coronary heart disease, hypertensive heart disease, and dilated cardiomyopathy. When these diastolic filling sounds occur in close proximity, a short rumbling murmur may be heard, which causes confusion of this sound with that of a valvular or congenital lesion. When both sounds occur exactly simultaneously, a single sound results. Often, this sound is louder than either the first or second sound and can be misinterpreted as either a valvular or congenital lesion. This, however, is a summation gallop, which is rare. For the most accurate timing of heart sounds and murmurs, the simple technique called "inching" is the best. Keeping the second sound in mind as a reference, the physician moves (inches) the stethoscope from the aortic area to the apex. An extra sound may be noted to occur in systole before the second sound, thereby diagnosing a systolic click. If the sound occurs after the second sound, however, it is an S3 or ventricular diastolic gallop. If a murmur appears before S2, it is a systolic murmur; if it appears after S2, it is a diastolic murmur. When the Austin-Flint murmur is heard, significant aortic regurgitation exists.(ABSTRACT TRUNCATED AT 400 WORDS)

Valvular heart disease

Medical signs of aortic regurgitation include increased pulse pressure by increased systolic and decreased diastolic blood pressure, but these findings may not be significant if acute. The patient may have a diastolic decrescendo murmur best heard at left sternal border, water hammer pulse, Austin Flint murmur, and a displaced apex beat down and to the left. A third heart sound may be present Mitral stenosis Patients with mitral stenosis may present with heart failure symptoms, such as dyspnea on exertion, orthopnea and paroxysmal nocturnal dyspnea, palpitations, chest pain, hemoptysis, thromboembolism, or ascites and edema (if right-sided heart failure develops). Symptoms of mitral stenosis increase with exercise and pregnancy

Heart sounds

Murmurs can be heard in many situations in adults without major congenital heart abnormalities: Regurgitation through the mitral valve is by far the most commonly heard murmur, producing a pansystolic/holosystolic murmur which is sometimes fairly loud to a practiced ear, even though the volume of regurgitant blood flow may be quite small. Yet, though obvious using echocardiography visualization, probably about 20% of cases of mitral regurgitation do not produce an audible murmur. Stenosis of the aortic valve is typically the next most common heart murmur, a systolic ejection murmur. This is more common in older adults or in those individuals having a two-leaflet, not a three-leaflet, aortic valve.

Phonoechocardiography and intracardiac phonocardiography in hypertrophic cardiomyopathy.

The salient phonoechocardiographic features of patients having hypertrophic cardiomyopathy (HCM) with or without left ventricular outflow tract (LVOT) gradients are reviewed. Intracardiac sound and pressure recordings from high fidelity catheter-tipped micromanometers have documented that the precordial murmur is the summation of both the systolic ejection murmur (SEM) arising from the LVOT, as well as the mitral regurgitant murmur recorded from the left atrium. The intensity of the precordial murmur varies directly with the LVOT gradient, which in turn is determined primarily by the contractility and loading conditions of the left ventricle. Reversed splitting of the second heart sound (S2) with paradoxical respiratory movement is a common finding in HCM, and when present, almost always denotes a significant LVOT gradient. It is due to marked lengthening of the left ventricular ejection time secondary to prolongation of the contraction and relaxation phases of left ventricular systole. The presence of a fourth heart sound (S4) is the rule in HCM when normal sinus rhythm is present, and is a reflection of a forceful left atrial contraction into a hypertrophied noncompliant left ventricle. A third heart sound (S3) is also common in HCM, and often the initial vibrations occur before the 0 point of the apexcardiogram (ACG) and continue giving the auscultatory impression of a diastolic rumble. When associated with a loud S1, which is frequently present, the clinical presentation may mimic mitral stenosis. This is particularly true when the patient has chronic atrial fibrillation. Careful attention to evidence of marked left ventricular hypertrophy as well as the typical echocardiographic findings of HCM preclude this diagnosis. In conclusion, phonoechocardiography is a simple non-invasive technique which almost always makes the definitive diagnosis of HCM.

Mitral regurgitation

Findings on clinical examination depend on the severity and duration of MR. The mitral component of the first heart sound is usually soft and with a laterally displaced apex beat, often with heave. The first heart sound is followed by a high-pitched holosystolic murmur at the apex, radiating to the back or clavicular area. Its duration is, as the name suggests, the whole of systole. The loudness of the murmur does not correlate well with the severity of regurgitation. It may be followed by a loud, palpable P2, heard best when lying on the left side. A third heart sound is commonly heard. Patients with mitral valve prolapse may have a holosystolic murmur or often a mid-to-late systolic click and a late systolic murmur. Cases with a late systolic regurgitant murmur may still be associated with significant hemodynamic consequences. Mitral regurgitation as a result of papillary muscle damage or rupture may be a complication of a heart attack and lead to cardiogenic shock. Cause

Valvular heart disease

On auscultation of a patient with mitral stenosis, there may be a holosystolic murmur at the apex, radiating to the back or clavicular area, a third heart sound, and a loud, palpable P2, heard best when lying on the left side. Patients also commonly have atrial fibrillation. Patients may have a laterally displaced apex beat, often with heave In acute cases, the murmur and tachycardia may be only distinctive signs. Tricuspid regurgitation Patients with tricuspid regurgitation may experience symptoms of right-sided heart failure, such as ascites, hepatomegaly, edema and jugular venous distension.

[Traumatic mitral insufficiency: a case report].

A 25-year-old man was admitted to Juntendo University Hospital with chief complaints of nocturnal dyspnea and shortness of breath on Sept. 22, 1983. He had no history of rheumatic fever or bacterial endocarditis. He was violently kicked in the chest while practicing Shorinji-Kempo (Karate) in July 1977. His heart murmur was first noticed in April 1978, but he was asymptomatic for six years after the accident until transient nocturnal dyspnea developed January 1983. Physical examination on admission revealed a grade 4/6 apical holosystolic murmur, a markedly accentuated third sound, and hepatomegaly of two finger breadth in the right midclavicular line. An electrocardiogram revealed sinus tachycardia (100/min), left atrial overload and left ventricular hypertrophy. Chest radiography showed slight cardiac enlargement with a cardiothoracic ratio of 55%, and slightly increased pulmonary vascular markings. Two-dimensional echocardiography showed a markedly prolapsed posterior mitral leaflet and fluttering in diastole. Cardiac catheterization showed elevated pressure of pulmonary capillaries (a: 16, v: 30, mean: 19 mmHg), the pulmonary artery and the right ventricle. Left ventriculography revealed grade four (Sellers) mitral regurgitation. Mitral valve replacement was performed on October 13, 1983. A chorda tendinae supporting the posterior leaflet of the mitral valve was found to be ruptured just above its origin from the posterior papillary muscle. Histological examination of the resected valve showed increased spongiosa tissue which mimicked so-called myxomatous changes, but it seemed preferable to interpret this as a "secondary change due to increased hemodynamic stress" rather than the "primary change".

[Phonocardiographic and Doppler echocardiographic study on the mechanism of the presystolic murmur in mitral stenosis, especially the relationship to mitral inflow dynamics].

The cause of the "presystolic murmur" in mitral stenosis was investigated by phonocardiography and continuous wave Doppler echocardiography in 31 patients with mitral stenosis and sinus rhythm classified into two groups: 18 patients with and 13 without "presystolic murmur". 1. The "presystolic murmur" group demonstrated high frequency vibrations preceding the first heart sound coinciding with the initial low frequency component of the first heart sound recorded at the apex in both groups. 2. There were two types of "presystolic murmur": The first type observed in three of the 18 patients occurred during the accelerated phase of the atrial (A) wave of mitral inflow signals and lasted until the first heart sound. The A wave velocity in mitral inflow signals was high at the onset and peak, and rapidly decreased after the peak. The second type observed in 15 patients occurred during the decelerated phase of the A wave and lasted until the first heart sound. The A wave velocity in mitral inflow signals was low at the onset, but high at the peak and rapidly decreased after the peak. 3. The mitral orifice area tended to be smaller in all patients with "presystolic murmur". The peak flow velocity, deceleration rate of the A wave, and maximal pressure gradient across the mitral valve during atrial contraction were significantly increased in all patients with "presystolic murmur". 4. Five patients with newly developed "presystolic murmur" after amyl nitrite inhalation had an increased initial low frequency component of the first heart sound coinciding with the latter half of "presystolic murmur". The rate of increase in the peak flow velocity and the deceleration rate of the A wave were significantly larger and the maximal atrioventricular pressure gradient during atrial contraction tended to be larger in these five patients than those in five who did not develop "presystolic murmur". 5. The peak flow velocity, deceleration rate of the A wave and the maximal atrioventricular pressure gradient during atrial contraction had increased 1 year later compared with those immediately after cardioversion of atrial fibrillation, and newly developed "presystolic murmur" appeared according to the recovery of left atrial mechanical function. These results suggest that the latter half of "presystolic murmur" originates from augmentation and prolongation of the initial low frequency component of the first heart sound up to the audible range caused by the sudden deceleration of mitral inflow velocity due to left ventricular contraction, and that the early half of "presystolic murmur" is the atriosystolic murmur produced by the increase in mitral inflow velocity during atrial contraction.

Heart murmur

Mitral regurgitation typically is a holosystolic (pansystolic) murmur heard best at the apex, and may radiate to the axilla or precordium. A systolic click may be heard if there is associated mitral valve prolapse. Valsalva maneuver in mitral regurgitation associated with mitral valve prolapse will decrease left ventricular preload and move the murmur onset closer to S1, and isometric handgrip, which increases left ventricular afterload, will increase murmur intensity. In acute severe mitral regurgitation, a holosystolic (pansystolic) murmur may not be heard. Pulmonary valve stenosis typically is a crescendo-decrescendo systolic murmur heard best at the left upper sternal border, associated with a systolic ejection click that increases with inspiration (due to increased venous return to the right side of the heart) and sometimes radiates to the left clavicle.

[Mitral valvular disease secondary to mitral ring calcification: a clinicopathologic study].

Fifteen cases with mitral valvular disease caused by mitral ring calcification (MRC) were observed among 2,800 consecutive autopsy patients more than 60 years of age. They consisted of one man and 14 women whose average age was 86.4 years. All had been diagnosed as having mitral valvular disease during life. For this clinicopathologic study, the cases were categorized as nine cases with mitral regurgitation (MR Group) and six with mitral stenosis (MS Group). Among the 15 cases, phonocardiograms were obtained in 14 and echocardiograms in 6. In addition, 122 cases with MRC, the length of which was 5 mm or more, were selected from 900 recent consecutive autopsies of senile patients, to evaluate the site of calcification and to analyze the ratio of calcification length to mitral valve ring circumference. The following conclusions were obtained: The prevalence of mitral valvular disease due to MRC in the aged was 15/2,800 (0.5%). MR was observed in nine cases and MS in six. Phonocardiograms of the MR Group revealed a holosystolic murmur in seven cases, a late systolic murmur in one, a third heart sound in four and a fourth heart sound in five. In the MS Group, a holosystolic murmur was found in four, a presystolic murmur in four, a diastolic rumble in one, but no opening snap in any case. A diamond-shaped systolic murmur was found in nine cases with MS or MR, suggesting an ejection systolic murmur caused by an associated calcified aortic valve. Echocardiograms showed markedly decreased DDR in five cases and increased echo intensity of the aortic valve in four. Pathologic findings revealed that the mean length of MRC was 36.6 mm in the MR Group and 58.0 mm in the MS Group. The calcification ring ratio (CRR = MRC/MVR X 100) was 50.3% in the MR Group and 69.8% in the MS Group. In the MR Group, MRC involved the anterolateral commissure in three, posteromedial commissure in five, and both in one. In five of six cases with MS, both commissures were involved by MRC. The study of 122 cases with MRC length greater than or equal to 5 mm suggested that MRC occurred first in the middle scallop of the posterior mitral leaflet, and extended to the posterior scallop, subsequently extending up to the anterior scallop, and finally involved the anterior mitral leaflet beyond the commissures.(ABSTRACT TRUNCATED AT 400 WORDS)

[Various etiologies of systolic murmurs radiating from the apex of the heart to the neck].

The authors studied systolic murmurs in 89 cases, 50 of aortic stenosis, 14 cases of obstructive cardiomyopathy and 20 cases of mitral incompetence. This systolic murmur is characterised by its exceptional intensity, its raspy character at the base, becoming softer at the apex and in the axilla, the presence of a thrill and irradiation into the neck in 50 to 75% of cases. The etiological diagnosis was ensured precisely by 1) pharmaco-dynamic tests: amyl nitrite accentuates the systolic ejection murmurs and attenuates murmurs due to mitral regurgitation. 2) careful analysis of diastole: a systolic murmur extending into early diastole, a third sound or an opening snap and a low-pitched diastolic murmur, suggest mitral incompetence. A high-pitched diastolic murmur is in favour of aortic stenosis. 3) the carotid arteriogram and catheterisation show the characteristic abnormalities of the carotid arteriogram found in aortic valve disease and the existence of a trans-aortic or intra-ventricular pressure gradient, when there is an obstruction to left ventricular jection. The F wave of the apex cardiogram or left atrial reflux of the contrast medium during cineangiocardiography, confirm mitral incompetence. The main phono-hemodynamic and phono-anatomical correlations have been emphasized: 1. The intensity of the systolic murmur is directly proportional to the degree of obstructive cardiomyopathy or mitral incompetence, but does not parallel the degree of the sub-valvular apparatus. 3. The maximum intensity of the murmur occurs all the later when the stenosis is tight, whilst it is earlier in severe obstructive cardio-myopathy. 4. The lozange shape of the murmur of mitral incompetence on phono-cardiography is, above all, due to those cases with lesions of the sub-valvular apparatus. Finally, a study of the sound recorded by the Allard-Laurens micromanometer permitted us to determine the mechanism of this irradiating systolic murmur.

Valvular heart disease

Tricuspid regurgitation Patients with tricuspid regurgitation may experience symptoms of right-sided heart failure, such as ascites, hepatomegaly, edema and jugular venous distension. Signs of tricuspid regurgitation include pulsatile liver, prominent V waves and rapid y descents in jugular venous pressure. Auscultatory findings include inspiratory third heart sound at left lower sternal border (LLSB) and a blowing holosystolic murmur at LLSB, intensifying with inspiration, and decreasing with expiration and Valsalva maneuver. Patients may have a parasternal heave along LLSB. Atrial fibrillation is usually present in patients with tricuspid regurgitation Causes

Heart murmur

Mitral stenosis typically presents as a diastolic low-pitched decrescendo murmur best heard at the cardiac apex in the left lateral decubitus position. It may be associated with an opening snap. Increasing severity will shorten the time between S2(A2) and the opening snap. (i.e. In severe MS the opening snap will occur earlier after A2) Tricuspid valve stenosis presents as a diastolic decrescendo murmur at the left lower sternal border, and signs of right heart failure may be seen on exam. Pulmonary valve regurgitation presents as a diastolic decrescendo murmur at the left lower sternal border. A palpable S2 in the second left intercostal space correlates with pulmonary hypertension due to mitral stenosis. Continuous and Combined Systolic/Diastolic Patent ductus arteriosus may present as a continuous murmur radiating to the back.

Valvular heart disease

On auscultation of a patient with mitral stenosis, typically the most prominent sign is a loud S1. Another finding is an opening snap followed by a low-pitched diastolic rumble with presystolic accentuation. The opening snap follows closer to the S2 heart tone with worsening stenosis. The murmur is heard best with the bell of the stethoscope lying on the left side and its duration increases with worsening disease. Advanced disease may present with signs of right-sided heart failure such as parasternal heave, jugular venous distension, hepatomegaly, ascites and/or pulmonary hypertension (presenting with a loud P2). Signs increase with exercise and pregnancy. Mitral regurgitation Patients with mitral regurgitation may present with heart failure symptoms, such as dyspnea on exertion, orthopnea and paroxysmal nocturnal dyspnea, palpitations, or pulmonary edema.

Heart sounds

"ta-lub-dub" or "a-stiff-wall" It is a sign of a pathologic state, usually a failing or hypertrophic left ventricle, as in systemic hypertension, severe valvular aortic stenosis, and hypertrophic cardiomyopathy. The sound occurs just after atrial contraction at the end of diastole and immediately before S1, producing a rhythm sometimes referred to as the "Tennessee" gallop where S4 represents the "Ten-" syllable. It is best heard at the cardiac apex with the patient in the left lateral decubitus position and holding his breath. The combined presence of S3 and S4 is a quadruple gallop, also known as the "Hello-Goodbye" gallop. At rapid heart rates, S3 and S4 may merge to produce a summation gallop, sometimes referred to as S7. Atrial contraction must be present for production of an S4. It is absent in atrial fibrillation and in other rhythms in which atrial contraction does not precede ventricular contraction. Murmurs

Cardiovascular examination

For the best cardiac examination, it is important to have the patient both sit up and lay down at a 30-45˚ angle. Tapping with the fingertips (also known as percussion) can be used to estimate the size of the heart, though palpation is more accurate. From the left side of the chest, the doctor can tap the spaces between the ribs with the tips of their middle finger to listen for the dullness that will be present over the heart. Listening with a stethoscope (also known as auscultation) to all four areas of the heart: aortic, pulmonic, tricuspid and mitral. Any murmurs, rubs or gallops should be noted. Gallops are also known as a third (S3) or fourth (S4) heart sound. The absence of abnormalities (normal) may be recorded as "no m/r/g". The ACC and the AHA have called cardiac auscultation "the most widely used method of screening for valvular heart disease." Because of its importance to the cardiac examination, cardiac auscultation has been covered in-depth elsewhere.

Mitral Valve Insufficiency -- History and Physical

The majority of patients suffering from chronic MR are asymptomatic, but serial quantitative assessment and follow-up of a patient with asymptomatic MR have shown a significant impact on the survival and clinical outcome. [28] Due to the insidious and slowly progressive nature of chronic MR, patients may not report any specific symptoms and may not notice a progressive decline in functional status during the early phase of the disease by gradual modification of their activities. Bedside evaluation for valvular heart disease is very important as management highly depends on symptoms as well as the severity of valvular lesions. Patients with MR are usually referred due to symptoms of chest pain, shortness of breath, palpitations, leg swelling, or just incidental finding of systolic murmur on physical examination. A thorough history of prior bacterial or viral infections, rheumatic fever, trauma, ischemic events, invasive cardiac/noncardiac procedures and family history with a comprehensive review of systems should be obtained. A detailed physical examination with particular attention to the cardiovascular system, including pulse, apical impulse, jugular veins, edema, signs of congestive heart failure, and assessment of characteristic systolic murmur with other pertinent findings should be documented. [29] [3] A characteristic holosystolic murmur present at the apex and radiating to the left axilla can be present most of the time except in cases of MVP where the murmur appears in mid-late systole with or without midsystolic click. The murmur should not be confused with other systolic murmurs such as aortic stenosis, tricuspid regurgitation, pulmonic stenosis, ventricular septal defect, benign flow murmurs, and other cardiac disorders in the spectrum. [30]

Heart click

With newer, non-invasive imaging techniques, the origin of other, so-called adventitial sounds or heart clicks has been appreciated. These are short, high-pitched sounds. The mitral valve in cases of mitral stenosis may open with an opening snap on the beginning of diastole. Patients with mitral valve prolapse may have a mid-systolic click along with a murmur, referred to as apical late systolic murmur. Early systolic clicks may also be present in some patients. Aortic and pulmonary stenosis may cause an ejection click immediately after S1. References Symptoms and signs: Cardiac Audible medical signs

The maverick heart sound.

An asymptomatic 29-year-old woman presented for prenatal counselling. She had a history of a heart murmur since childhood and a previous echocardiogram suggesting 'enlargement of the heart'. Physical exam revealed normal jugular venous pressure and contour. Precordial palpation was unremarkable. Auscultation, however, was abnormal; findings on inspiration and expiration are presented in Figure 1, sound clip. Based on the phonocardiogram and online supplementary audio clip, which of the following is correct? An early diastolic filling sound (S3) is heard, indicating increased right ventricular filling pressures.An ejection click without respiratory variation and a systolic ejection murmur are heard, consistent with bicuspid aortic valve stenosis.An ejection click with respiratory variation and a systolic ejection murmur are heard, consistent with pulmonic valve stenosis.A holosystolic murmur with inspiratory augmentation is heard, indicating tricuspid regurgitation.

Mitral Regurgitation -- History and Physical -- Chronic Mitral Regurgitation [27]

Patients often remain asymptomatic until late in the course. Clinical findings common to all etiologies include fatigue, dyspnea on exertion, orthopnea, paroxysmal nocturnal dyspnea, weight gain, widening of pulse pressure, apical holosystolic murmur with radiation to the axilla, dependent edema, displaced apical impulse, and jugular venous distension. In more advanced cases, there may also be syncope or near syncope, cyanosis, clubbing of digits, gross anasarca, hepatomegaly, evidence of ascites with a fluid wave, or shifting dullness, and evidence of pleural or pericardial effusions. These latter findings are reflective of the development of pulmonary hypertension and resultant right ventricular systolic dysfunction from chronic pressure overload. The differential diagnosis is also considerably broader, and specific clinical findings are dependent on the etiology.

NEW THORACIC MURMURS, WITH TWO NEW INSTRUMENTS, THE REFRACTOSCOPE AND THE PARTIAL STETHOSCOPE.

1. An understanding of the physics of sound is essential for a better comprehension of refined auscultation, tone analysis, and the use of these instruments. 2. The detection of variations of the third heart sound should prove a valuable aid in predicting mitral disease. 3. The variations of the outflow sound should prove a valuable aid in determining early aortic lesions with the type of accompanying intimal changes. 4. The character of chamber timbre as distinct from loudness heard as the first and second heart sounds denotes more often the condition of heart muscle, and must not be confounded with valvular disease. 5. The full significance of sound shadows is uncertain. Cardiac sound shadows appear normally in the right axilla and below the left clavicle. Their mode of production is quite clear. 6. Both the third heart sound and the outflow sound may be heard with the ordinary stethoscope.

Auscultation In patients with severe AR, the aortic valve closure sound (A2) is usually absent. A systolic ejection sound is audible in patients with BAV disease, and occasionally an S4 also may be heard. The murmur of chronic AR is typically a high-pitched, blowing, decrescendo diastolic murmur, heard best in the third intercostal space along the left sternal border (see Fig. 267-5B). In patients with mild AR, this murmur is brief, but as the severity increases, it generally becomes louder and longer, indeed holodiastolic. When the murmur is soft, it can be heard best with the diaphragm of the stethoscope and with the patient sitting up, leaning forward, and with the breath held in forced expiration. In patients in whom the AR is caused by primary valvular disease, the diastolic murmur is usually louder along the left than the right sternal border. However, when the murmur is heard best along the right sternal border, it suggests that the AR is caused by aneurysmal dilation of the

When does a fourth sound become an atrial gallop?

A study of the fourth sound was conducted on 100 normal subjects (ages 1-88 years) and 42 clinical cases with either aortic stenosis, systemic hypertension or coronary heart disease. This study was based on the graphic recognition of a presystolic sound when the tracing was taken with the use of one or more of 5 different high pass filters. Attention was paid to the existence of the fourth sound, its magnitude, and its vibrational frequency. In general it was accepted that a magnitude of 1/2 of the first heart sound or a frequency of 30 Hz denoted a pathologic fourth sound. However, exceptions were found among normal subjects, so that only the combination of the two criteria could be considered highly significant for a pathologic phenomenon (gallop). Patients with aortic stenosis presented an increase in magnitude of the fourth sound but incidence and vibrational frequency were similar to those of controls. Patients with hypertension had a greater incidence of fourth sounds, especially in middle age (100%); middle age patients usually had a greater magnitude while older patients had more often an increase in vibrational frequency. Patients with coronary heart disease (evidence of old infarcts) had an increase in the incidence, magnitude, and vibrational frequency in comparison with controls. These data and the cause of the fourth sound are discussed. The fourth sound has been repeatedly studied in the past, both as an auscultatory finding and a graphic phenomenon. Attempts were made for separating the normal fourth sound from that denoting a pathological phenomenon but, so far, no clear cut criteria for the differentiation have been obtained. We thought, therefore, that a new study was indicated.

Gallavardin phenomenon

The Gallavardin phenomenon is a clinical sign found in patients with aortic stenosis. It is described as the dissociation between the noisy and musical components of the systolic murmur heard in aortic stenosis. The harsh noisy component is best heard at the upper right sternal border radiating to the neck due to the high velocity jet in the ascending aorta. The musical high frequency component is best heard at the cardiac apex. The presence of a murmur at the apex can be misinterpreted as mitral regurgitation. However, the apical murmur of the Gallavardin phenomenon does not radiate to the left axilla and is accentuated by a slowing of the heart rate (such as a compensatory pause after a premature beat) whereas the mitral regurgitation murmur does not change. The sign is named after Louis Gallavardin, having been described by Gallavardin and Ravault in 1925. References Symptoms and signs: Cardiac

"Presystolic" augmentation of diastolic heart sounds in atrial fibrillation.

In the presence of atrial fibrillation, the diastolic murmur of mitral stenosis can appear augmented during early systole before the mitral valve closure sound. This phenomenon has previously been thought to be due to increased blood flow velocity across the narrowing mitral valve orifice. We have observed patients in whom the third heart sound (S3) gallop, the diastolic flow murmur of atrial septal defect and mitral insufficiency and the initial muscular component of the first heart sound become more intense during this period with short, critically timed cycle lengths. This phenomenon appears to be neither peculiar to nor indicative of mitral stenosis and is probably a direct result of the initial muscular contraction of an underfilled ventricle. Either the contraction itself or the sudden deceleration of the rapidly moving flow of blood across the atrioventricular orifice may produce the sound.

Implications of third heart sounds in patients with valvular heart disease. The Veterans Affairs Cooperative Study on Valvular Heart Disease.

The presence of third heart sounds in patients with valvular heart disease is often regarded as a sign of heart failure, but it may also depend on the type of valvular disease. We assessed the prevalence of third heart sounds and the relation between third heart sounds and cardiac function in 1281 patients with six types of valvular heart disease. The prevalence of third heart sounds was higher in patients with mitral regurgitation (46 percent) or aortic regurgitation (28 percent) than in those with aortic stenosis (11 percent) or mitral stenosis (8 percent). The left ventricular ejection fraction was significantly lower (P less than 0.001) when a third heart sound was detected in patients with aortic stenosis (0.38, vs. 0.56 in those without third heart sounds) or mixed aortic valve disease (0.40 vs. 0.55). However, the ejection fraction was only slightly lower in patients with mitral regurgitation and third heart sounds (0.51 vs. 0.57, P = 0.03). The pulmonary-capillary wedge pressure was higher (P less than 0.001) when a third heart sound was detected in patients with aortic stenosis (18.6 mm Hg, vs. 12.1 mm Hg in those without third heart sounds). There was no association between the wedge pressure and third heart sounds in patients with mitral regurgitation. The prevalence of third heart sounds increased with the severity of mitral regurgitation. In patients with mitral regurgitation, third heart sounds are common but do not necessarily reflect left ventricular systolic dysfunction or increased filling pressure. In patients with aortic stenosis, third heart sounds are uncommon but usually indicate the presence of systolic dysfunction and elevated filling pressure.

Heart failure

Additional signs indicating left ventricular failure include a laterally displaced apex beat (which occurs if the heart is enlarged) and a gallop rhythm (additional heart sounds) may be heard as a marker of increased blood flow or increased intracardiac pressure. Heart murmurs may indicate the presence of valvular heart disease, either as a cause (e.g. aortic stenosis) or as a result (e.g. mitral regurgitation) of heart failure.
