冠状动脉造影正常的青年人患急性心肌梗死13例临床分析

Clinical analysis of acute myocardial infarction in youth with normal coronary arteriography

目的:探讨冠状动脉造影(CAG)正常的青年人患急性心肌梗死(AMI)的临床特点。方法:回顾性分析486例接受CAG检查的AMI患者,探讨CAG正常的青年人患AMI的临床特点。结果:在486例中,青年AMICAG正常者13例(2.67%),分析其临床特点,本组患者多无梗死前心绞痛、高血压病、血脂异常、糖尿病及冠心病家族史。吸烟者较多,多在应激、超量吸烟情况下发病。结论:在冠状动脉造影正常的青年人患AMI中,心肌梗死可能与冠状动脉痉挛、血栓形成、冠状动脉栓塞等因素有关,这些患者预后良好。

Objective ： To investigate the morbidity and clinical characteristics of acute myocardial infarction （AMI） in youth with normal coronary angiography （CAG）. Methods：We analyzed the results of CAG and some correlated risk factors in 486 patients with AMI and investigated their clinical characteristics. Results：Of the total number of AMI patients, 13 （2.67%） were young ones with normal CAG, most of whom were smokers but free of angina pectoris, hypertension, diabetes mellitus and hyperlipidemia. Conclusion：AMI in youth with normal CAG is associated with coronary artery spasm and/or thrombus formation, generally with better prognosis than in those with coronary stenosis.
