The incidence of sudden cardiac arrest (SCA) in Asians is lower than that seen in Western populations, but there are few available data on the incidence and associated cardiac etiology of SCA in Asians. From 2002 to 2013, patients with SCA were analyzed using a cohort from the South Korean National Health Insurance Service (NHIS) coded database. Sudden unexplained death syndrome (SUDS) was defined as cryptogenic arrest, excluding that of non-cardiac origin, coronary artery disease (CAD), cardiomyopathy (CM), and valvular heart disease. During the 12-year study period, 5,973 patients (0.53%) from the total cohort of 1,125,691 had a cardiac arrest code. The overall incidence of arrest was 48.7 per 100,000 person-years (95% CI 16.6–18.0). The incidence of primary SCA excluding those of non-cardiac origin was 16.1 per 100,000 person-years (95% CI 15.4–16.8). It was higher in males than in females (18.1 vs. 14.1 per 100,000 person-years). CAD was the most common cause of SCA (59.4%), and followed by CM (13.9%). SUDS accounted for 14.7% of SCA events. The risk of SCA had increased gradually from over 25 years old. Heart failure, atrial fibrillation and hypertension are major factors associated with SCA incidence. Our findings outline epidemiologic data for SCA and the proportion of associated cardiac etiology leads SCA in a large population.

亚洲人的心脏骤停（SCA）发生率低于西方人群，但是亚洲人中关于SCA的发生率和相关的心脏病因的可用数据很少。从2002年到2013年，使用来自韩国国民健康保险服务（NHIS）编码数据库的队列分析了SCA患者。突发性无法解释的死亡综合征（SUDS）被定义为隐源性逮捕，不包括非心脏起源，冠状动脉疾病（CAD），心肌病（CM）和瓣膜性心脏病。在为期12年的研究期间，总人数1125691中的5973名患者（占0.53％）的心脏骤停代码。逮捕的总发生率为每100,000人年48.7（95％CI 16.6–18.0）。不包括非心脏起源的主要SCA发生率为每100,000人年16.1（95％CI 15。4–16.8）。男性高于女性（每100,000人年18.1比14.1）。CAD是SCA的最常见原因（59.4％），其次是CM（13.9％）。SUDS占SCA事件的14.7％。SCA的风险从25岁以上开始逐渐增加。心力衰竭，心房纤颤和高血压是与SCA发病率相关的主要因素。我们的研究结果概述了SCA的流行病学数据，以及在大量人群中，相关心脏病因的比例导致SCA。房颤和高血压是与SCA发生率相关的主要因素。我们的研究结果概述了SCA的流行病学数据，以及在大量人群中，相关心脏病因的比例导致SCA。房颤和高血压是与SCA发生率相关的主要因素。我们的研究结果概述了SCA的流行病学数据，以及在大量人群中，相关心脏病因的比例导致SCA。
