ABSTRACT
BACKGROUND/AIMS@#The optimal strategy for anticoagulation treatment in patients with atrial fibrillation (AF) and end-stage renal disease (ESRD) has not been established. We evaluated the efficacy and bleeding risk of warfarin and antiplatelet agents in patients with AF and ESRD.@*METHODS@#We retrospectively reviewed the medical records of 256 patients with AF and ESRD and included 158 patients (age, 63.7 ± 12.2 years; male sex, n = 103) with a CHA2DS2-VASc score ≥ 1 who were taking warfarin (n = 53) or an antiplatelet agent (n = 105).@*RESULTS@#During the follow-up period (31.0 ± 29.4 months), 10 ischemic events and 29 major bleeding events occurred. The thromboembolic event rate did not significantly differ between the warfarin and antiplatelet groups (1.9% and 8.6%, respectively; p = 0.166). However, the rate of major bleeding events was significantly higher in the warfarin group than it was in the antiplatelet group (32.1% and 11.4%, respectively; p = 0.002). Cox's regression analysis indicated that warfarin was related to an increased risk of major bleeding events (hazard ratio [HR], 3.44; 95% confidence interval [CI], 1.60–7.36; p = 0.001). Conversely, warfarin was not related to a decreased risk of thromboembolic events (HR, 0.34; 95% CI, 0.04–2.70; p = 0.306).@*CONCLUSIONS@#In patients with AF and ESRD, warfarin use was associated with an increased risk of bleeding events, compared with antiplatelet agents.
