RT Journal Article SR Electronic A1 Rizzo, Toni T1 Silent Atrial Fibrillation: When to Treat? JF MD Conference Express YR 2012 FD SAGE Publications VO 12 IS 8 SP 20 OP 21 DO 10.1177/155989771208010 UL http://mdc.sagepub.com/content/12/8/20.abstract AB Atrial fibrillation (AF) is the most common sustained cardiac rhythm disorder, affecting 3 million people in the United States and 35 million worldwide. Patients with AF have a substantial risk for mortality and morbidity from ischemic stroke, which occurs at 5 times the rate as in the general population. The risk of stroke in people with AF is about 5% per year and AF-related strokes tend to be more severe than strokes in patients without AF [Magnani JW et al. Circulation 2011]. This article discusses the diagnosis and treatment of silent AF.
