The most common sources of pulmonary<unk>  (PE) are proximal leg deep venous thromboses (DVTs) or pelvic vein thromboses; therefore, any risk factor for DVT also increases the risk of PE.  Approximately 15% of patients with a DVT will develop a PE.  In these chapters on venous thromboembolism (VTE), the word risk factors refers to those epidemiologic and genetic variables that expose someone to a higher risk of developing venous thrombosis.  The word triggers refer to those factors in the patients immediate history or environment that may have lead to the occurrence of the venous thrombosis.  The risk factors for VTE are a constellation of predisposing conditions which stem from the three principles of Virchow's triad: stasis of the blood flow, damage to the vascular endothelial cells, and hypercoagulability.  Approximately 5 to 8% of the U.S. population has one of several genetic risk factors, also known as inherited thrombophilias in which a genetic defect can be identified that increases the risk for thrombosis. The risk factors for VTE can be classified as temporary, modifiable and non-modifiable.  It is suggested that venous thrombosis also shares risk factors with arterial thrombosis, such as obesity, hypertension, smoking, and diabetes mellitus.
