Summary

This article discusses results from a European study, demonstrating that although the management of patients with atrial fibrillation (AF) has changed based on updated guidelines, many continue to experience symptoms, highlighting the need to improve the management of this patient population. The Prevention of Thromboembolic Events - European Registry in Atrial Fibrillation [PREFER in AF] is a multicenter study conducted across seven countries in Europe, comprising a prospective, observational disease registry. The study was designed to determine the extent to which publication of the 2010 European Society of Cardiology guidelines has affected clinical behavior in Europe.
