中青年急性心肌梗死临床特点的探讨（附68例冠状动脉造影分析）

对26例＜50岁及61例＞60岁急性心肌梗死（AMI）患者进行对比观察，其中68例选择性冠状动脉造影，探讨中青年人AMI的临床特点。结果表明：老年组比中青年组具有更多的危险因素，老年组临床多有心绞痛；中青年组急性心力衰竭较老年组高，心肌梗死发作多有明显诱因，始大量饮酒，超负荷运动等；病死率两组相似。提示中青年人AMI的高危性应引起临床重视。

Clinical features of acute myocardial infarction in the young and middle-aged patients: analysis of 68 cases of coronary artery angiography]

OBJECTIVE: This study was to evaluate the clinical features of acute myocardial infarction (AMI) in young and middle-aged patients. METHODS: Eighty-seven patients were classified into two groups according to the age. Among them, 61 patients were 60 years old and above, 26 patients below 50 year old. Selective coronary artery angiography was performed on 68 cases and a scoring method which reflects the extent of narrowing of coronary artery was also used. RESULTS: The older group had more risk factors than the young group. The angina pectoris in the young group was less than the older group. The incidence of acute heart failure in the young group was higher than the older group. The mortality of both two groups had no significant differences. CONCLUSION: The high risk of AMI in the young and middle-aged patients should be paid more attention in the clinic.
