Dialysis Patients with Atrial Fibrillation: Warfarin and Risk of Stroke and Bleeding
MedicalResearch.com Interview with:
Louise Pilote, MD, MPH, PhD

MedicalResearch.com: What are the main findings of the study?
Dr. Pilote: Our study found that in patients with atrial fibrillation (AF) undergoing dialysis, warfarin use, compared to no-warfarin use, did not reduce the risk for stroke (adjusted hazard ratio (HR): 1.14, 95% confidence interval (CI): 0.78 to 1.67) but it was associated with a 44% higher risk for bleeding event (adjusted HR: 1.44, 95% CI: 1.13 to 1.85). However, warfarin use in non-dialysis patients with AF was associated with a 13% lower risk for stroke (adjusted HR: 0.87, 95% CI: 0.85 to 0.90) and only a 19% higher risk for bleeding event (adjusted HR: 1.19, 95% CI: 1.16 to 1.22).
