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。
Objective To improve the diagnosis of acute myocardial infarction in the elderly and reduce the incidence of misdiagnosis and risk of myocardial infarction. Methods All acute myocardial infarction patients with acute myocardial infarction were divided into the correct diagnosis group and misdiagnosed two groups, the two groups of symptoms, ECG characteristics were compared. Results The incidences of chest distress and non-ST-segment elevation in the misdiagnosis group were higher than those in the correct diagnosis group (P <0.01, P <0.05). Conclusion The main symptoms of chest tightness and non-ST-segment elevation of electrocardiogram in elderly patients with acute myocardial infarction should be based on comprehensive analysis of the history, the dynamic electrocardiogram and the myocardial enzymology monitoring results, and timely diagnosis and risk stratification assessment.
