Atrial fibrillation (AF) is associated with approximately one-third of ischemic strokes, often debilitating or fatal. In up to 10%, AF is detected first at the time of stroke.1 Thromboprophylaxis with oral anticoagulant is very effective for prevention of cardioembolic stroke in AF,2 but screening strategies are needed to find clinically silent AF before stroke.
