There are roughly 10 million cases of<unk> s<unk> r year. In the United States,<unk> s are the primary cause of at least 10,000 to 12,000 deaths<unk> r year and a contributing cause in at least 30,000 to 40,000 deaths<unk> r year. True incidence involving<unk> s is unknown because they often go undiagnosed or unnoticed until autopsy. From 1993 to 2012, there have been an increased number of admissions in hospitals due to<unk> s, jumping from 23 cases<unk> r 100,000<unk> ople to 65 cases<unk> r 100,000<unk> ople. Despite this increase, there has been a decrease in mortality during that same time<unk> riod due to medical advances that have occurred. Venous thromboembolism (VTE), a common risk factor, is present at much higher rates in those over the age of 70 (three times higher compared to those aged 45 to 69). This is likely due to there being a generally lower level of activity among the elderly, resulting in higher rates of immobility and obesity. VTE has a large, and continuously rising, case fatality rate. This rate is roughly 10% after 30 days, 15% after three months and up to 20% after one year.<unk> s alone (when resulting in hospitalizations) have a case fatality rate of about 5% to 10% so VTE can play a large factor in the severity of the<unk> s. When looking at all cases, the rate of fatal<unk>  emboli has declined from 6% to 2% over the last 25 years in the United States. In Europe, an average of approximately 40,000 deaths<unk> r year with<unk>  as the primary cause were reported between 2013 and 2015, a conservative estimate because of potential underdiagnosis.
