AbstractFactors associated with an increased risk of thromboembolic events in patients with atrial fibrillation (AF) include increasing age, rheumatic heart disease, poor left ventricular function, previous myocardial infarction, hypertension and a past history of a thromboembolic event. Patients with AF should be considered for anticoagulation or antiplatelet therapy based on the patient's age, the presence of other risk factors for stroke and the risk of complications from anticoagulation. In general, patients with risk factors for stroke should receive warfarin anticoagulation, regardless of their age. In patients who are under age 65 and have no other risk factors for stroke, either aspirin therapy or no therapy at all is recommended. Aspirin or warfarin is recommended for use in patients between 65 and 75 years of age with no other risk factors, and warfarin is recommended for use in patients without risk factors who are older than 75 years of age.
