title: Nonvalvular atrial fibrillation and stroke: a review.
abstract: Nonvalvular atrial fibrillation accounts for more than thirty percent of all strokes above the age of sixty years. The use of anticoagulants for the primary prevention of stroke has been a controversial issue for a long time. New data has emerged which clarifies some of these issues and helps in selecting patients who are at a higher risk of stroke.
