摘要：目的：探讨青年急性心肌梗死患者冠状动脉造影正常的发生率,并分析其临床特点。方法：回顾分析了1995年5 月至2005年10月436例AMI 患者冠状动脉造影结果及有关冠心病的危险因素。结果：436例中青年AMI冠脉造影正常者为8例,分析其临床特点,该组多无心绞痛、高血压病、糖尿病及血脂异常史,大量吸烟者居多。结论：在冠脉造影正常的青年AMI中，冠脉痉挛在心肌梗死的发病中可能起着十分重要的作用;急性血栓形成伴血栓自溶亦是其病理改变之一。

    Abstract：Objective：To investigate the morbidity rate and clinical characteristics of young acute myocardial infarction (AMI) with normal coronary angiograms (CAG). Method：The results of CAG and some correlated risk factors in 436 patients with AMI enrolled from May 1995 to Oct. 2005 were analysed. Result：The younger patients with AMI and normal CAG accounted for 8 patients , most of whom were somkers ,but free of angina pectoris , hypertension , diabetes millitus and hyperlipidemia. Conclusion：CAG negative is not infrequent in patients with AMI. The results indicate that coronary artery spasm play an important role in AMI with normal CAG, Acute thrombosis and auto -thromobolysis is also one of the pathologic changes. ......
