Apixaban versus Aspirin for Embolic StrokeIn a trial of 352 patients with embolic stroke of undetermined source, 5 mg of apixaban administered twice daily was compared with 100 mg of aspirin administered once daily for the prevention of recurrent ischemic strokes. At 12 months, 13.6% of patients given apixaban had new ischemic lesions on magnetic resonance imaging compared with 16.0% of patients given aspirin, and the rates of clinically relevant bleeding were also comparable.
