Newly Detected Atrial Fibrillation and Compliance With Antithrombotic Guidelines

Abstract
Stroke is a devastating complication of atrial fibrillation (AF), occurring when blood clots formed in the atria embolize to the brain. Results of several randomized controlled trials have demonstrated that warfarin treatment significantly decreases the risk of stroke in patients with AF1-9 and that the rate of stroke is modified by existing cardiovascular disease (CVD) risk factors.4,10-13 The American College of Chest Physicians (ACCP) and the American College of Cardiology (ACC) recommend antithrombotic therapy for most patients with AF, with the selection of antithrombotic agent individualized to the patient's level of CVD risk.14,15
