[目的]探讨青年人(≤45岁)AMI的危险因素、诱发因素、临床特点、治疗状况、临床转归及冠状动脉造影结果,特别是探讨其危险因素以引起人们的重视,从而采取相应措施,降低发病风险。[方法]于2005年1月～2009年12月对收治的38例青年人急性心肌梗死和60例老年人急性心肌梗死患者,进行危险因素、诱发因素、临床表现、治疗状况、临床转归及冠状动脉造影结果对比分析。[结果]结果显示青年AMI和老年AMI的主要危险因素均有高血脂、高血压、糖尿病,且青年组患者的危险因素多于老年组(P﹤0.05)。青年组冠状动脉造影结果显示,单支病变比老年组多,双支病变、三支病变及以上者比老年组少。青年组均有典型心绞痛症状,故能及时就诊,进行静脉溶栓治疗的比例高,临床疗效好,并发症少,死亡率低。[结论]青年AMI患者临床表现典型,冠心病危险因素多,冠状动脉狭窄程度轻,并发症少,预后好。
[Objective] To explore the risk factors, predisposing factors, clinical features, treatment status, clinical outcome and coronary angiography findings of AMI in young people (≤ 45 years old), especially to explore the risk factors for AMI, and to take corresponding measures , Reduce the risk of onset. [Methods] From January 2005 to December 2009, 38 patients with acute myocardial infarction and 60 elderly patients with acute myocardial infarction were enrolled in the study. The risk factors, predisposing factors, clinical manifestations, treatment status, clinical outcome, Coronary angiography contrast analysis. [Results] The results showed that the main risk factors of AMI and AMI were hyperlipidemia, hypertension and diabetes mellitus. There were more risk factors in young patients than in elderly patients (P <0.05). Coronary angiography in young group showed that single-vessel lesion was more than that of the elderly group, with double-vessel disease, three-vessel disease and above less than the elderly group. Young people have typical symptoms of angina, it can be timely treatment, the proportion of intravenous thrombolytic therapy, clinical efficacy, fewer complications, low mortality. [Conclusion] The clinical manifestations of young AMI patients are typical, with many risk factors of coronary heart disease, light coronary stenosis, fewer complications and good prognosis.
