It remains unclear if the CHADS2 score or CHA2DS2-VASc score is more useful for the risk stratification of ischemic stroke/systemic thromboembolism in Japanese patients with non-valvular paroxysmal atrial fibrillation (NVPAF). We retrospectively investigated the incidence of ischemic stroke on the basis of CHADS2 and CHA2DS2-VASc scores in 332 NVPAF patients (224 men, mean age, 65 ± 13 years) who were not administered anticoagulation therapy before publication of the 2008 JCS guideline (mean follow-up period, 53 ± 35 months). Annual rates of ischemic stroke/ systemic thromboembolism underlying antiarrhythmic drug therapy were 0.2
