老年人急性心肌梗死108例临床观察

目的 提高对老年人急性心肌梗死的诊断率,减少误诊率和心肌梗死危险事件的发生.方法 急性心肌梗死所有急性心肌梗死病人分为正确诊断组和误诊两组,对两组的症状、心电图特点进行率的比较.结果 误诊组中胸闷和心电图非ST段抬高的发生率分别高于正确诊断组(P＜0.01,P＜0.05).结论 老年人急性心肌梗死以胸闷为主要症状和心电图非ST段抬高,要结合病史、动态心电图和心肌酶学监测结果综合分析,及时诊断,进行危险分层评估.

Acute myocardial infarction in the elderly ( clinical analysis of 108 cases)

Objective To improve the correct diagnostic rate of acute myocardial infarction in the elderly,to decrease the misdiagnostic rate and complications.Methods Symptoms and ECG characteristics of correct diagnostic group and misdiagnostic group were compared.Results Chest tightness and non-ST elevation myocardial infarction were more likely to occur in the misdiagnostic group than in the correct diagnostic group(P<0.01 and P<0.05,respectively).Conclusion The main symptoms of acute myocardial infarction in elderly patients are chest tightness with no ST elevation on ECG.We must comprehensively analyse the case history,dynamic electrocardiogram and myocardial enzyme results to make a timely diagnosis and risk stratification.
