猝死是缺血性心脏病的重要问题,病因学诊断主要靠尸检。如果急性心肌梗塞已发展至坏死期,诊断比较容易;死于数小时内者,由于无统一的病理诊断标准,故诊断较为困难。本文根据世界卫生组织的方案,重点研究新近心肌梗塞与各种冠状动脉病变和死亡过程的关系。方法:对24小时内死亡的151例作尸检,其中男性114例(38～83岁),女性37例(44～90岁)。摘录死前28天内的前驱症状,并从患者用药情况判断死前病情。吸烟习惯按程度分类。先作冠状动脉造影以显示病变,然后纵行切开仔细检查,根据各支冠 Sudden death is an important issue of ischemic heart disease, etiological diagnosis mainly by autopsy. If acute myocardial infarction has been developed to necrosis, the diagnosis is relatively easy; died within a few hours, due to no uniform pathological diagnostic criteria, so the diagnosis is more difficult. This article, based on the WHO program, focuses on the relationship between recent myocardial infarction and various coronary artery disease and death processes. Methods: One hundred and fifteen patients died within 24 hours were autopsy, including 114 males (38-83 years) and 37 females (44-90 years). Extract the prodromal symptoms within 28 days before death and judge the antecedent condition from the patient’s medication. Smoking habits are categorized by degree. Coronary angiography for the first show lesions, and then carefully examined longitudinal incision, according to the crown
