目的探讨心源性猝死案例的病因、诱发因素及法医病理学特点,以期为心源性猝死案件的法医病理诊断提供参考。方法收集法医病理检案中的心源性猝死案例,对其年龄、性别、死亡时间、死因、诱因及场所等流行病学特点进行回顾分析。结果 300例心源性猝死案例中男性多于女性,18-45岁发病最多;病因包括冠心病（129例）,心肌病（78例）,心肌炎（36例）等;应激为SCD最常见的诱发因素（157例）。结论 1应激和冠心病是心源性猝死的重要危险因素。2心源性猝死的法医学鉴定除了要进行系统的尸检及病理学检查外,还要对死者的相关资料如：基础疾病、诱因、死亡时间、死亡经过等进行全面系统的分析以明确死因。

Methods Cases of sudden was investigating the pathogeny, risk factors and forensic death in order to provide references for forensic pathological cardiac death were collected from Department of Forensic Medicine, Guiyang Medical College. Epidemiological features, such as age, gender, postmortem interval, cause of death, predisposition and scenes of the crime in cases of sudden cardiac death were retrospectively analyzed. Results In all the defuncts of 300 cases of sudden cardiac death cases , men was more than women. The peak incidence of age is 18 -45 years old.
