Atrial fibrillation (AF) is a common arrhythmia in the adult population. It is associated with up to a 5-fold increased risk of stroke and contributes to a higher morbidity and mortality compared with non–AF-related strokes. 1 The current prevalence of AF in the adult population, estimated at 1% to 2%, is expected to increase by up to 5 times by 2050, which will in turn increase the overall burden of ischemic stroke in the aging population. 2, 3 Various stroke risk stratification schemes have been developed to quantify stroke risk in patients with AF and guide preventive treatment decisions for the clinician. The most widely used has been the CHADS2 score, which estimates risk based on the presence of congestive heart failure, hypertension, age 75 years or greater, diabetes mellitus, and prior stroke or transient ischemic attack (TIA). 4A revision of the CHADS2 scheme has been developed for use in stroke risk assessment in AF. It dichotomizes age and incorporates vascular disease and female sex, to create the CHA2DS2-VASc (VA, vascular disease; Sc, sex category) score5 (Table 1). Compared with CHADS2, this stroke risk stratification scheme is better able to discriminate among individuals at lowest risk. 6–8 For example, in patients with a CHADS2 score of 0, the 1-year stroke and embolic event rates range from 0.84%(CHA2DS2-VASc score of 0) to 3.2%(CHA2DS2-VASc score of 3). 8 By both risk stratification schemes, those patients who score≥ 1 are recommended to receive oral anticoagulant therapy unless major contraindications are present. Only those who are< 65 years of age and
