Prevention of atherothrombotic and thromboembolic events in atrial fibrillation In adult patients with atrial fibrillation who have at least one risk factor for vascular events, are not suitable for treatment with vitamin-K antagonists and who have a low bleeding risk, clopidogrel is indicated in combination with ASA for the prevention of atherothrombotic and thromboembolic events, including stroke.
