老年人急性心肌梗死临床特点及近期预后的相关危险因素分析

目的 探讨老年人急性心肌梗死（AMI）临床特点及影响近期预后的相关危险因素。方法 回顾性分析122例老年AMI患者资料，年龄大于60岁，根据发病后4周内预后分为存活组和死亡组。对发病时的年龄、性别、吸烟史，是否合并高血压病、糖尿病、高脂血症及AMI发病后24h内TG、TC水平用t检验或χ^2检验方法，进行单因素分布；同时对影响老年人AMI预后的相关危险因素进行多元Logistic回归分析。结果 单因素分析表明：年龄、吸烟、糖尿病、高血压病和高脂血症在生存组和死亡组之间的差异有统计学意义。多因素分析发现年龄每增加1岁，其死亡危险性增加1．34倍；吸烟者死亡危险性是非吸烟者的6．02倍；有高脂血症史者死亡危险性是无高脂血症史者4、78倍。结论老年人AMI症状不典型，易漏诊误诊；年龄、吸烟史、糖尿病、高血压病和高脂血症史是影响老年人AMI近期预后的高危因素。

Analysis of related risk causes influencing early prognosis and clinical features in the aged patients with acute myocardial infarction

Objective To investigate clin ic al features and the risk causes of early prognosis in the aged patients with auc te myocardial infarction(AMI).Methods The data for analysis wer e collected from 72 cases of the elderly beyond 60 years old with AMI.They were divided into two groups(survival group and fatality group) according to the earl y prognosis(within four weeks).Mono-factor or multivariate Logistic regression was performed.Results Mono-factor analysis revealed that there were statistically significant differences in age,smoking,high plasma-choleste rol(TC) and the level triglyceride(TG) of AMI between those two groups.Multi-fa ctor analysis discovered that patients with increased fatality were characterize d by a cluster of risk factors such as age,smoking,history of high TC and TG of AMI.Conclusion Age,smoking,diabetes,high plasma-cholesterol(TC ) and the level of triglyceride(TG) of AMI were the high risk factors influencin g the early prognosis and aged patients with AMI.
