Risk of stroke in people on oral anticoagulants for atrial fibrillation


  • People with atrial fibrillation (AF) who have a stroke despite oral anticoagulation have a higher risk for recurrent strokes than those without prior oral anticoagulation.

Why this matters

    Although oral anticoagulation can reduce the risk of stroke in people with AF, the optimal prevention strategy in this high risk group remains unclear. The findings help identify a group at high risk of a subsequent stroke who require better prevention strategies.
