Evidence supports the use of heparin in people following surgery who have a high risk of thrombosis to reduce the risk of DVTs; however, the effect on PEs or overall mortality is not known. In hospitalized non-surgical patients, mortality does not appear to change. It does not appear, however, to decrease the rate of symptomatic DVTs. Using both heparin and compression stockings appears better than either one alone in reducing the rate of DVT. In hospitalized people who have had a stroke and not had surgery, mechanical measures (compression stockings) resulted in skin damage and no clinical improvement. Data on the effectiveness of compression stockings among hospitalized non-surgical patients without stroke is scarce. The American College of Physicians (ACP) gave three strong recommendations with moderate quality evidence on<unk> E prevention in non-surgical patients: * that hospitalized patients be assessed for their risk of thromboembolism and bleeding before prophylaxis (prevention); * that heparin or a related drug is used if potential benefits are thought to outweigh potential harms; * and that graduated compression stockings not be used. As an ACP policy implication, the guideline stated a lack of support for any performance measures that incentivize physicians to apply universal prophylaxis without regard to the risks. Goldhaber recommends that people should be assessed at their hospital discharge for persistent high-risk of<unk>  and that people who adopt a heart-healthy lifestyle might lower their risk of<unk> . People who have cancer have a higher risk of<unk> E and may respond differently to anticoagulant preventative treatments and prevention measures. For people undergoing chemotherapy for cancer who are able to walk (ambulatory), low molecular weight heparins treatment (LMWH) decreases the risk of<unk> E. Due to potential concerns of bleeding its routine use is not recommended. For people who are having surgery for cancer, it is recommended that they receive anticoagulation therapy (preferably LMWH) in order to prevent a<unk> E. LMWH is recommended for at least 7–10 days following cancer surgery, and for one month following surgery for people who have a high risk of<unk> Es. In adults who have had their lower leg casted, braced, or otherwise immobilized for more than a week, LMWH may decrease the risk and severity of deep vein thrombosis, but does not have any effect on the incidence of pulmonary embolism . LMWH is recommended for adults not in hospital with an above-knee cast and a below-knee cast, and is safe for this indication. Following the completion of warfarin in those with prior<unk> E, the use of long-term aspirin has been show to be beneficial.
