青年男性ST段抬高急性心肌梗塞的特点及院内转归

Clinical Manifestations of Young Male Adults with ST Segment Elevation Acute Myocardial Infarction

目的探讨青年男性ST段抬高急性心肌梗塞(AMI)患者的危险因素、冠脉造影特点、临床特点及院内转归。方法对年龄≤44岁的青年男性AMI患者(61例,青年组)与同期同病同性别年龄≥65岁、<75岁(老年组)的AMI患者(61例)就其危险因素、冠脉造影、临床特点及院内转归进行对比分析。结果冠心病危险因素青年组高血压、糖尿病明显少于中年组;吸烟青年组高于老年组,低密度脂蛋白胆固醇、阳性家族史两组无明显差别;冠脉造影青年组单支病变多,累及回旋支(LCX)多,右冠状动脉(RCA)少;老年组双支及双支以上病变多,多累及LCX,RCA。与老年组相比,青年组住院天数、心肌酶、机械并发症及死亡构成差别无统计学意义。结论年轻心梗患者大量吸烟者多,单支病变多,有糖尿病、高血压病史者少,但年轻心梗患者院内转归与老年组相似。

Objective To compare and analyze risk factors and coronary angiography of young and older male adults with ST segment elevation acute myocardial infarction. Method During hospitalization period, 61 cases of an initial ST segment elevation acute myocardial infarction（AMI） who were admitted to our hospital and who were under or 44 years of age （young group） were compared to 61 patients who were over or 65 but under 75 admitted during the same time for same reason （older group）. Result Young group had fewer patients with hypertension and diabetes mellitus, and more have smoking habit, and had a higher prevalence of single-vessel disease and a higher incidence of left circumflex coronary artery and a lower incidence of right circumflex coronary artery. The length of hospitalization, maxCKMB, major complications and death in young group showed no differences from those of the older group. Conclusion Young group had more cigarette consumption, more single-vessel lesion. In-hospital outcome in young male ST-elevated AMI is comparable to that of older-age group.
