The SINGLE-AF randomized trial found that direct oral anticoagulants reduced the risk of serious clinical events by 69% in atrial fibrillation patients with intermediate stroke risk. The primary benefit came from a significant reduction in ischemic strokes, while major bleeding rates did not increase compared to control groups.


This finding suggests that anticoagulation therapy may benefit a broader group of atrial fibrillation patients than currently treated, potentially preventing strokes in intermediate-risk patients who might otherwise go untreated. The lack of increased bleeding risk strengthens the safety profile for this patient population.


Direct oral anticoagulants cut the risk of serious clinical events by 69% in atrial fibrillation patients with an intermediate risk of stroke, according to the randomized SINGLE-AF trial. The benefit was driven mainly by fewer ischemic strokes, with no increase in major bleeding.
