1137例不同年龄急性心肌梗死患者心脏功能与预后关系的分析

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。

Relation between cardiac function and prognosis in 1 137 patients with acute myocardial infarction

Objective To explore relation between ecbocardiographic 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.
