冠状动脉造影正常的急性心肌梗死(附36例临床分析)

目的观察冠状动脉正常的急性心肌梗死(AMI)患者的临床和血管造影特点。方法2000-08～2004-10间,435例AMI患者中36例血管造影显示冠状动脉完全正常,分析患者的临床和冠状动脉造影特点及有关冠心病的危险因素。结果435例AMI患者中冠脉造影正造常者为36例,占8.2%。分析其特点:该组患者中多年龄较年轻,无心绞痛史、高血压史、糖尿病史及血脂异常,大量吸烟者居多为特征。结论AMI患者中冠脉造影正常者并非少见,提示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是其病理改变之一。

Clinical Analysis on Acute Myocardial Infarction in Normal Angiography of Coronary Artery

Objective To observe the clinical manifestation and angiography characteristics of normal angiography of coronary artery on AMI. Methods The clinical materials of 36 of 435 cases of such patient and their risk factors were analyzed retrospectively from August 2000 to October 2004. Results There were 36 cases of normal angiography among 435 AMI patient (8.2%). Their age was young, who smoke without past history such as hypertension, diabetes. Conclusion It was not rare for AMI with normal angiography. The coronary artery spasm might play important role in AMI and acute embolism be mechanism of self solution as pathology.
