What are the recommendations for antithrombotic therapy for patients with nonvalvular AF?
The 2012 American College of Chest Physicians evidence-based suggested that patients with nonrheumatic AF at low stroke risk (ie, CHADS2 =0) be treated with no therapy rather than any antithrombotic agent (American College of Chest Physicians grade 2B; ie, weak recommendation, moderate evidence); for those patients preferring antithrombotic treatment, aspirin rather than anticoagulation was recommended (grade 2B).
