Does warfarin reduce stroke risk or increase bleeding risk in patients with atrial fibrillation undergoing dialysis?
In patients with atrial fibrillation on dialysis, warfarin does not reduce stroke risk but significantly increases the risk of bleeding.
Our results suggest that warfarin use is not beneficial in reducing stroke risk, but it is associated with a higher bleeding risk in patients with AF undergoing dialysis.
Shah et al. (2014) studied this question.
