摘　　要：目的分析不同年龄的老年心肌梗死（AMI）患者心脏超声特点。方法308例急性心肌梗死患者，按年龄分为A（60—69岁）、B（70～79岁）C（80岁以上）3组，分析各组患者一般资料及超声指标。结果随着年龄的增大，高血压、心力衰竭、心房颤动、后下壁心梗、再发心梗死亡及心源性死亡的患者显著增多（P〈0．05），各组患者LVEF以50％为节点、左心房内径以39mm为节点、左心室内径以50mm为节点差异均有统计学意义（P〈0．05）。冠状动脉狭窄≥70％3组之间差异有统计学意义。结论彩色多普勒超声对于70岁以上的高危AMI患者，具有重要的临床筛查诊疗意义，但对于血流动力学不稳定的患者及冠状动脉严重钙化等患者，还尚且有一定的局限。Objective To analyze echocardiographic finding characteristics of acute myocardial infarction （AMI） among different age elderly patients. Methods 308 cases of AMI were divided into group A（60 -69 years old） , group B （70 - 79 years old） and group C （80 or more years old）. The general information and echocardiographic indicators in each group were analyzed. Results The incidence of hypertension, heart failure, atrial fibrillation, rear inferior wall myocardial in- farction the death caused by recurrent myocardial infarction and cardiac death were increased significantly with the ages of patients（ P 〈 O. 05 ）,the differences of the above indicators among the three groups were observed at LVEF of 50% , left atrial diameter of 39ram,left ventricular internal diameter of 50 ram（ P 〈 0.05 ）. There were also significant difference in the proportion of coronary artery stenosis ≥70% among the three groups（ P 〈 O. 05 ）. Conclusion Echocardi0graphy has specific clinical significance of screening, diagnosis and treatment for high-risk AMI patients over 70 years, but there were still a certain limitations in the patients with hemodynamie instability and severe coronary calcification.
