目的探讨青年心肌梗死患者的临床特点、冠状动脉病变特点及预后。方法 97例年龄≤44岁接受冠状动脉介入治疗的青年急性心肌梗死患者为青年组,抽取同期97例年龄≥60岁急性心肌梗死患者作为老年组。收集整理患者临床资料进行分析。结果青年组男性比例(96.9%)高于比老年组(75.3%)(P<0.01);青年组单支病变为58.8%,高于老年组的32.0%(P<0.01),罪犯血管多为前降支。传统危险因素中青年组吸烟为75.3%,高脂血症为64.9%,分别高于老年组的36.1%、28.9%(P<0.01)。青年组住院期间急性左心衰发生较少,无死亡病例。结论青年急性心肌梗死患者主要危险因素为男性、吸烟、高脂血症。冠状动脉病变以单支血管病变为主,血栓负荷重,常累及前降支;短期预后相对较好。
Objective To investigate the clinical characteristics of young patients with myocardial infarction, coronary artery lesions and prognosis. Methods Ninety-seven youth patients with acute myocardial infarction undergoing coronary intervention were enrolled in this study. Ninety-seven patients with acute myocardial infarction aged ≥60 years were enrolled as the elderly group. Collect and analyze the clinical data of patients for analysis. Results The proportion of male in youth group was significantly higher than that in elderly group (96.9%) (75.3%) (P <0.01). The single-vessel disease in youth group was 58.8%, higher than that in elderly group (32.0%, P <0.01) Before the descending branch. The traditional risk factors were 75.3% in young group and 64.9% in hyperlipidemia group, which were higher than those in elderly group (36.1%, 28.9%, P <0.01). Youth hospitalized during acute left heart failure occurred less, no deaths. Conclusion The main risk factors for young patients with acute myocardial infarction are male, smoking and hyperlipidemia. Coronary artery lesions to the main single vessel disease, thrombus load, often involving the anterior descending artery; short-term prognosis is relatively good.
