Dabigatran versus warfarin in atrial fibrillation: Multicenter experience in Turkey

Abstract

Safety issues have been raised about dabigatran. We aimed to investigate the occurrence of safety outcomes in patients who had atrial fibrillation and a risk of stroke. We analyzed 439 patients prescribed dabigatran (n = 220) or warfarin (n = 219). Ischemic stroke occurred in 15 (6.8%) patients in the warfarin group versus 5 (5.2%) patients in the 110-mg group versus 1 (0.8%) patient in the 150-mg dabigatran group (P =.015). Intracranial hemorrhage occurred in 6 (2.7%) patients in the warfarin group versus 3 (2.4%) patients in the 150-mg dabigatran group (P =.104). Death from any cause occurred in 10 (4.6%) patients in the warfarin group versus 1 (1.0%) patient in the 110-mg dabigatran group (P =.005). Dabigatran was associated with less ischemic stroke and death from any cause than warfarin. Dabigatran may be a better option for stroke prophylaxis, where recommended monitoring with warfarin is suboptimal. © SAGE Publications.
