Stroke risk scores for prediction of mortality and hemorrhages in atrial fibrillation patients

Abstract

Background: Atrial fibrillation (AF) is an emerging epidemic worldwide, responsible for a twofold increase in mortality, independent of other risk factors. Stroke prevention is the cornerstone of AF management. However, oral anticoagulation imposes an increased risk of bleeding. Several risk scores have been developed for estimating both the thromboembolic and the bleeding risks. The aim of the study was to determine the usefulness of different stroke risk scores as predictors of mortality and hemorrhagic events in AF patients.
