We performed a cross-sectional survey of stroke and acute myocardial infarction (AMI) in Okinawa, Japan with a census population of about 1.2 million. A total of 3,644 cases of first-ever stroke and 898 cases of initial acute myocardial infarction (AMI) were detected. The age-adjusted annual incidence rate for stroke was 105 per 100,000 standard population of Japan, and that of AMI was 26. The case-fatality rate of stroke within 28 days of onset was 12.8%, and that of AMI was 22.2%. Of the stroke cases, 51.4% were diagnosed as brain infarction, 38.7% as brain hemorrhage, and 9.3% as subarachnoid hemorrhage. The diagnosis of stroke subtypes were confirmed by computed tomography or magnetic resonance imaging in 98.4% of all stroke cases. In Okinawa, the incidence rate of AMI was still considerably lower than that in the Western population, and the rate of stroke was similar to that in the Western population.
我们对日本冲绳地区进行了一项横断面调查，该地区普查人口约120万。共检测出3644例首次发生的中风病例和898例初始急性心肌梗死（AMI）病例。按年龄调整后的中风年发病率为每10万日本标准人口105例，AMI为26例。中风发病28天内的病死率为12.8%，AMI为22.2%。在中风病例中，51.4%被诊断为脑梗死，38.7%为脑出血，9.3%为蛛网膜下腔出血。98.4%的中风病例通过计算机断层扫描或磁共振成像确诊为中风亚型。在冲绳，AMI的发病率仍远低于西方人群，中风发病率与西方人群相似。
