冠状动脉造影正常的急性心肌梗死患者的临床特点

The clinical features of the patients of acute myocardial infarction with normal coronary arteriography.

目的 :探讨冠状动脉造影 (CAG)正常的急性心肌梗死 (AMI)患者的发生机制及临床特点。方法 :分析 2 0 0 0年 6月至 2 0 0 1年 10月86例AMI患者的CAG结果及冠心病相关危险因素。结果 :86例中CAG正常者 8例 ,年龄 ( 39+11 4 ) ( 2 5～ 52 )岁 ;多无心绞痛史、高血压史、糖尿病史、血脂异常史及家族史 ;以情绪波动、精神压抑、大量吸烟、饮酒史者居多。结论 :冠状动脉痉挛、血栓自溶或溶栓治疗后血栓消失是其主要发生机制 ;冠状动脉正常的AMI患者其貌似正常 ,实属高危人群 。

Objective:To investigate the pathogenic mechanism of acute myocardial infarction(AMI)with normal coronary arteriography(CAG)and the clinical features.Methods:The CAG results of 86 patients with AMI from June in 2000 to October in 2001 and the related risk factors of coronary heart disease were analyzed.Results:In 8 of 86 patients had normal CAG,these patients aged(39±11\^4).Most of them free of angina pectoris,hypertension,diabetes mellitus\,hyperlipidemia and family history,but emotional lability,mental depression,heavy smoke and drinking history were significant features of these patients(P<0\^05).Conclusions:The primary mechanism of AMI with normal CAG were coronary artery spasm\,auto-thrombolysis or disappearance of thrombus after thrombolytic therapy;The AMI patients with normal CAG look like normal,but they are the high risk group in fact,high degree of attention should be paid to these patients.
