Rates of associated stroke and pre-stroke anticoagulation in patients with atrial fibrillation


  • Approximately 20–30% of strokes are associated with atrial fibrillation (AF), but anticoagulation therapy is only used in about 20% of patients with AF prior to a stroke.

Why this matters

    Population-level efforts to increase the rate of anticoagulation therapy among patients with AF could lower rates of incident stroke.
