目的探讨急性ST段抬高性心肌梗死患者冠状动脉造影正常的病因并分析其临床特点。方法 31例患者均经股动脉或桡动脉途径行常规冠状动脉造影,经多体位、多角度投照,冠状动脉造影未见任何病变或仅见轻微病变者视为正常。结果 31例冠状动脉造影正常者多为年龄较轻、既往无心绞痛、高血压病、糖尿病及高血脂症等病史,大量吸烟者居多为其主要特征。结论冠脉造影正常的急性ST段抬高性心肌梗死患者年龄较小,多无心绞痛、高血压、糖尿病病史及血脂异常,且以大量吸烟者居多。提示冠脉痉挛和急性血栓形成并血栓自溶是其主要发病机制。
Objective To investigate the etiopathogenisis of coronary angiography in patients with acute ST-segment elevation myocardial infarction and to analyze its clinical features. Methods All 31 patients underwent routine coronary angiography via the femoral artery or radial artery. All patients underwent multi-position and multi-angle projection, no coronary angiography or only slight lesion was considered as normal. Results Of the 31 patients with normal coronary angiography, they were mostly younger and had no previous history of angina pectoris, hypertension, diabetes and hyperlipidemia. Most smokers were the main characteristics. Conclusions Patients with normal ST-segment elevation myocardial infarction with normal coronary angiography are younger and have no history of angina pectoris, hypertension, diabetes mellitus and dyslipidemia, and are predominantly smokers. Tip of coronary spasm and acute thrombosis and thrombolysis is the main pathogenesis.
