The Prevalence of Risk Factors for Thromboembolic and Hemorrhagic Complications among Patients with Atrial Fibrillation

V.I. Tseluyko, N.A. Opolonskaya


The paper presents the results of a study on prevalence of risk factors for thromboembolic and hemorrhagic complications in patients with non-valvular atrial fibrillation during long-term follow-up for 2 years. A detailed analysis of specific risk factors has been carried out in patients using scales CHADS2, CHA2DS2-VASc and HAS-BLED. Depending on baseline risk, we determined the incidence of endpoints (stroke, TIA, hemorrhagic complications or death from cardiovascular causes or a combination of outcomes). We established the dependence between prevalence of thromboembolic and hemorrhagic complications and the number of points by scales CHA2DS2-VASc and HAS-BLED.
