HealthDay -- In atrial fibrillation patients, dabigatran may reduce the risk of stroke or systemic embolism more effectively than warfarin, according to a study published online Aug. 30 in the New England Journal of Medicine and presented at the European Society of Cardiology Congress 2009, held from Aug. 29 to Sept. 2 in Barcelona, Spain. Another study, published Aug. 27 in the Journal of the American Society of Nephrology, concludes that warfarin may increase the risk of stroke in atrial fibrillation patients who also have end-stage renal disease.
