Thromboembolic and Bleeding Risk Stratification in Patients With Non-valvular Atrial Fibrillation

Summary

The aim of the present prospective study is to further develop and validate a composite risk score predicting both ischemic and bleeding risk, based on epidemiologic, clinical, biological, and/or morphologic complementary data. First, the investigators will assess the predictive performance of current clinical risk scores. Second, the investigators will assess the potential predictive value of additional markers. Third, the investigators will aim to develop a new risk score.
