徳島県における急性心筋梗塞症に対する治療の現状 : 多施設合同研究結果

Although considerable information is available regarding the prognosis after acute myocardial infarction (AMI) in urban populations, little is known about the local subjects in Japan. The purpose of this study was to assess short-term mortality and reperfusion therapy after AMI in Japan. From October 1999 to October 2000, 256 patients with AMI from 16 hospitals in Tokushima Prefecture were studied. Mean age of AMI in Tokushima was elder than another country (men : 65.0 yrs, women : 71.6 yrs). Although, patients of in-hospital death were twenty-three (9.0%). Two patients were cardiopulmonary arrest on arrival. Reperfusion therapy performed for 82.8% of all patients. Only one patient treated by CABG (coronary artery bypass grafting). Hospital admission within 6 hours of symptom onset was 61.6% of all patients. These data suggest that short-term mortality was reasonable by adequate reperfusion therapy. Earlier reperfusion therapy will improve clinical outcome in Tokushima.
