1 137例急性心肌梗死患者临床表现及超声心动图特点

目的探讨急性心肌梗死患者临床表现及超声心动图特点。方法对1993年1月至2005年5月首都医科大学宣武医院收治的1 137例急性心肌梗死患者的临床表现、超声心动图检查结果进行分析。结果年轻急性心肌梗死患者(年龄<40岁)男性多于女性,超声心动图显示心腔大小改变不明显,大部分患者心功能正常。高龄急性心肌梗死患者(年龄≥75岁)男性与女性发病率基本一致,症状多不典型,超声心动图示左心室重构者较多,心功能多降低。40~74岁心肌梗死患者临床表现介于两者之间。结论年轻急性心肌梗死患者心脏功能及结构改变不明显,预后较好。高龄急性心肌梗死患者心脏功能及结构改变明显,预后较差。

Clinical and Echocardiographic Characteristics in 1 137 Patients with Acute Myocardial Infarction

Objective To investigate clinical and echocardiographic characteristics in patients with acute myocardial infarction(AMI).Methods 1 137 patients with AMI were analyzed in clinical terms of characteristics and echocardiographic menifestations.Results Left ventricular remolding and impaired cardiac function were found less compared with elderly patients in young patients with AMI,and more males than females in this group.Male patients with AMI were about equal to female in elderly patients with AMI.Symptoms of elderly patients with AMI were not typical.And high incidence in left ventricular remolding and left ventricular dysfunction was discovered in elderly patients with AMI.Symptoms in 40~74 years old group displayed between young and elder patients with AMI in clinic.Conclusion Young patients with AMI have good prognosis.Severe abnormalities in cardiac structure and function are observed in elderly patients with AMI.Elderly patients with AMI have poor prognosis.
