目的 探讨冠状动脉造影影像正常的急性心肌梗死病例的临床特点。方法 在 34 9例诊断急性心肌梗死患者行选择性冠状动脉造影检查 ,其中有 17例冠状动脉影像正常 ,分析这 17例患者的性别、年龄、临床症状及预后。结果 冠状动脉影像正常的急性心肌梗死占 17/34 9(4 87% ) ,平均年龄 (4 3 6± 6 32 )岁 ,45岁以下者 15例 ,全部为男性 ,临床无心衰、休克及严重心律失常等并发症 ,预后好。结论 急性心肌梗死可以发生在正常的冠状动脉基础上 ,此种情况多发生在 45岁以下的男性患者 ,病前多健康 ,临床无严重并发症 ,预后好 ,预防冠状动脉痉挛是该病的主要策略
Objective To investigate the clinical features of acute myocardial infarction with normal coronary angiography. Methods Selective coronary angiography was performed in 34 9 patients with acute myocardial infarction. Among them, 17 patients had normal coronary arteries and their gender, age, clinical symptoms and prognosis were analyzed. Results Acute myocardial infarction with normal coronary arteries accounted for 17/34 9 (477%) with an average age of (436 ± 6 32) years. Among those 45 years of age and below, 15 were all male and had no clinical heart failure, shock and Serious arrhythmia and other complications, the prognosis is good. Conclusions Acute myocardial infarction can occur on the basis of normal coronary arteries. This condition occurs mostly in male subjects below 45 years of age. Pre-morbidities are more healthy and have no serious clinical complications. The prognosis is good and prevention of coronary artery spasm is the major cause of the disease Strategy
