目的：了解冠心病病因，同时了解冠状动脉病变部位、范围及程度，以指导临床对冠心病治疗并估计预后。方法：对我院８８例临床确诊为冠心病患者行冠状动脉造影（冠脉造影）。结果：冠脉狭窄≥５０％者７２例，占总数８２％；冠脉正常１６例，其中冠脉痉挛１０例，Ｘ综合征６例。老年组冠脉狭窄８９％，非老年组７４％（０．０２５＜Ｐ＜０．０５）。冠脉单支受累老年组２２％，非老年组５０％，冠脉双支、多支受累老年组７８％，非老年组５０％（０．００１＜Ｐ＜０．０２５）。结论：老年人冠心病病因以冠状动脉粥样硬化为主，冠脉病变以双支、多支受累多见，预后较差。非老年人冠心病病因常为多因素，冠脉病变以单支受累多见，预后较好。 Objective: To understand the etiology of coronary heart disease, at the same time to understand the location of coronary lesions, extent and extent to guide clinical treatment of coronary heart disease and prognosis. Methods: 88 cases of clinical diagnosis of coronary heart disease in our hospital coronary angiography (coronary angiography). Results: There were 72 cases (≥ 82%) of coronary stenosis, accounting for 82% of the total. Coronary artery was normal in 16 cases, including 10 cases of coronary spasm and 6 cases of syndrome X. Coronary stenosis was 89% in the elderly group and 74% in the non-elderly group (0.025
