冠状动脉造影正常的急性心肌梗死患者临床特点的分析

Clinical Analysis of Normal Coronary Arteriography with Acute Myocardial Infarction

目的 :探讨急性心肌梗死 (AMI)患者行冠脉造影为正常者的发生率 ,并分析其临床特点。方法 :回顾分析 394例 AMI患者冠状动脉 (冠脉 )造影结果及有关冠心病的易患因素。结果 :394例 AMI患者中冠脉造影正常者为 30例 ,占7.6%。冠脉造影正常者的 AMI患者以年龄较轻 ,多无心绞痛病史、高血压病史、糖尿病史及血脂紊乱 ,吸烟者居多及发病前有过度劳累史为特点。结论 :AMI冠脉造影正常者 ,提示冠脉痉挛在心肌梗死的发病中起着十分重要的作用 。

Objective:To investigate the morbidity rate and clinical characteristics of acute myocardiol infarction (AMI)with normal coronary angiograms (CAG).Methods:The results of CAG and some correlated risk factors in 394 patients with AMI. Results: Normal CAG accounted for 30(7 6%)of 394 patients,most of whom were the younger and somkers,but free of angine pectoris,hypertension,diabetes millitus and hyperlipidemia (P<0 01).Conclusion:CAG negative is not infrequent in patients with AMI.The results indicate that coronary artery spasm play an important role in AMI,Acute thrombosis and auto-thromobolysis is also one of the pathologic changes.
