摘要: The CHADS2 score has been proposed for stratifying patients with nonvalvular atrial fibrillation (NVAF) according to the risk of thromboembolism in AHA/ACC/ESC guidelines. However, there is little information about its usefulness predicting long-term ischemic stroke Japanese paroxysmal AF. We retrospectively evaluated incidence and efficacy anticoagulant therapy AF on rhythm control who were stratified by their score. subjects 334 NVAF (229 men 105 women, mean age, 68 ± 12 years, follow-up period, 60 35 months) categorized into low (score 0), moderate (1 or 2), high (3 more) groups thromboembolism.The low, moderate, accounted 34%, 50%, 16% patients, respectively. Among 257 without warfarin therapy, annual rate symptomatic was 0.6% 0 group, 0.5% 1 3.1% 2 9.6% 3 more group. 77 treated (target PT-INR: 1.6-3.0), 0% 1.4% 6.6% 0.88% versus 2.67% those warfarin, a decrease 68% (P < 0.01). In AF, useful stroke. Anticoagulant needed prevent especially have more.
