目的 观察冠状动脉造影正常年轻人心肌梗死的临床和血管造影特点。方法 1996年 1月～ 2 0 0 0年 3月 315例心肌梗死患者中 2 6例血管造影显示冠状动脉完全正常 ,其中 7例年龄 <45岁。回顾性分析患者的临床和冠状动脉造影特点。结果 7例患者均为男性 ,平均年龄 41岁。既往均无高血压、糖尿病、高血脂及冠心病家族史 ,前壁梗死 5例 ,下壁梗死 2例。 7例患者均有发病前大量吸烟、劳累和紧张等明确诱发因素 ,其中 4例于发病后 12小时内入院行静脉溶栓治疗 ,预后良好 ,另外 3例入院时间超过 12小时而行一般药物治疗 ,出院时留有不同程度心功能不全。结论 年轻人心肌梗死可发生在冠状动脉完全正常患者中 ,一般都有明确诱因 ,及时入院行溶栓治疗预后良好
Objective To observe the clinical and angiographic characteristics of myocardial infarction in normal young patients with coronary artery angiography. Methods Twenty-six of the 315 patients with myocardial infarction from January 1996 to March 2000 were examined by angiography. Coronary arteries were completely normal, of which 7 were 45 years old. Retrospective analysis of patients with clinical and coronary angiography features. Results All 7 patients were male, with an average age of 41 years. No previous history of hypertension, diabetes, hyperlipidemia and family history of coronary heart disease, anterior wall infarction in 5 cases, inferior wall infarction in 2 cases. All 7 patients had significant smoking, fatigue and nervous factors before onset, of which 4 were admitted to hospital within 12 hours after onset of intravenous thrombolytic therapy, the prognosis was good, the other 3 patients admitted to hospital for more than 12 hours while the general drug treatment , Leaving different degrees of cardiac insufficiency at discharge. Conclusion Young myocardial infarction may occur in patients with completely normal coronary arteries, generally have a clear incentive, timely admission thrombolytic therapy prognosis is good
