青年人急性心肌梗死临床特点及冠脉造影结果分析

目的探讨青年急性心肌梗死（AMI）患者危险因素、临床特点、冠状动脉病变特点。方法对青年组56例（〈45岁）AMI患者、老年组156例（≥60岁）AMI患者的临床特点及冠脉造影结果进行对比分析。结果青年AMI组危险因素如吸烟、男性、超重、心血管病家族史、血脂异常明显多于老年组（P〈0.01或P〈0.05）,发病时症状较老年人典型（P〈0.01）,并发症明显少于老年患者（P〈0.01）。冠脉造影（CAG）显示青年患者冠脉病变以单支、局限性病变为主,而老年组则以多支病变多见（P〈0.05）。结论青年人AMI患者吸烟、男性、家族史、血脂异常是其发病的重要危险因素;发病时症状典型、并发症少;CAG显示冠脉正常者占有一定比例。

Anlysis of characters of young AMI

Objective To study and analyze risk factor,clinic characteristics and coronary lesions in young AMI.Methods The clinical data including results of coronary angiography of 56（45 years old） young and elderly（≥60 years old） AMI patients were retrospectively analyzed.Results Smoking,male,obesity,family history,and hihertriglyceride levels of cardiovascular disease were more common in young cases（P0.01 or P0.05）.The typical chest pain symptom often more in young group and complications less than eldly group（P0.01）.Focal and single-vessel appeared more in young group,while multi-vessel lesions more in elderly group（P0.05）.Conclusion Smoking,male,positive family history and hyperlipidemia were are risk factors for young AMI.Young AMI also had typical symptoms and fewer complications.Normal coronary artery is frequent in young patients.
