无临床表现的冠心病猝死的病理学研究

Sudden death of coronary artery disease without clinical symptom:A pathological study of 6 cases

作者从冠心病的尸检例中选出死前无冠心病临床表现的6例猝死病例结合对照组进行分析。结果发现:2例左室前壁大范围心肌梗死,2例冠状动脉开口狭窄和闭塞,2例窦房结动脉管壁增厚、管腔狭窄和结细胞轻度变性。引起猝死的诱因多为过劳,精神紧张,过敏和上呼吸道感染等。

Autopsy of sudden death of coronary artery disease without chinical symptom before death were observed in 6 cases. The results showed that all cases had obvious coronary athoroscleroscerosis in many branches, of which 2 had greater part of myocardial infarction the front wall of left ventricle, and another 2 had narrow entrance of coronary artery; remaining 2 had thicker wall of sinoatrial artery, cavity became narrow; and nodal cell degenarated. Sudden death is directly related to coronary athorosclerosis, myocardial infarction, and narrow entrance of coronry artery. But diseases of conducting system of heart are of especial importance in sudden death.
