Brief Summary

Venous thromboembolism occurs with an incidence of about 1 per 1000 per year in adults . The main consequences are death, recurrence, post-thrombotic syndrome and major bleeding due to anticoagulation. Mortality rates are lower among patients with idiopathic venous thrombosis and higher among those in whom thrombosis occurs in the presence of cancer. The risk increases with the age for unclear reasons. There are also differences in the incidence according to ethnicity; however, data in subjects of European ancestry are scarce. Several studies have documented an association between thrombosis and ABO group. Specifically, non-O blood groups have a higher risk of myocardial infarction, angina, peripheral vascular disease, cerebral ischemia and venous thromboembolism than O. While there are numerous studies carried out in patients who have already shown thromboembolic events, data on the incidence of risk factors in the healthy population are completely inadequate. Understanding the risk factors for venous thrombosis is necessary to maximize the prevention of this disease in individuals and groups of high-risk patients . For this purpose a self-administered questionnaire will be used. Data obtained by blood donors on exposure to risk factors will be used to set up a clinical score to validate in future studies to carry out in patients with VTE.
