摘　　要：目的探讨不同年龄急性心肌梗死患者超声心动图表现与预后的关系。方法选择急性心肌梗死患者1 137例,按年龄分为<45岁组(44例)、45～74岁组(905例)、≥75岁组(188例)。根据超声心动图表现及临床心脏并发症进行分析。结果 <45岁组患者男性比例最高,随着年龄增加男性比例逐渐减少,3组间差异有统计学意义(P<0.05)。<45岁组患者有8例(18.2%)发生心脏严重并发症,45～74岁组患音有216例(23.9%)发生心脏严重并发症,≥75岁组患者有93例(49.5%)发生心脏严重并发症,3组间差异有统计学意义。结论≤45岁组急性心肌梗死患者心脏功能减低不明显,并发症少,预后较好。≥75岁组急性心肌梗死患者心脏功能减低明显,心脏并发症多,预后较差。Objective To explore relation between echocardiographic characteristics and prognosis in 1 137 patients with acute myocardial infarction（AMI）. Methods 1 137 patients with AMI were divided into 3 groups（〈45y, 45-74y, ≥75y）. They were analyzed according to echocardiographic manifestation and complication. Results The proportion of male patients was higher than that of female patients in 〈45y group,and the proportion of males was decreased with increasing age. The severe complications happened in 8 patients （18.2%） in 〈45y group, 216 patients（23.9%） in 45-74y group and 93 patients（49.5%） in ≥75y group. There was statistical difference among the three groups （P〈0.05）. Conclusion The patients with AMI in 〈45y group have good prognosis. However,severe abnormalities in left ventricular function and more complications are observed in ≥75y group patients with AMI,who have poor prognosis.
