以往报道急性心肌梗塞(AMI)后心电图显示有左室肥厚(LVH)对于预报心性死亡是一项有价值的独立危险因素。然而,由于AMI后心电图显示有LVH的病人相对较少,或可能由于病人选择的偏差,其预后价值受到限制。作者对连续的4720例AMI进行前瞻性研究,以估价心电图显示有LVH的预后意义。方法研究对象为1981年7月～1983年8月13个医院的监护病房(CCU)中的AMI存
Previous reports of acute myocardial infarction (AMI) after electrocardiogram showed left ventricular hypertrophy (LVH) is a valuable independent risk factor for predicting cardiac death. However, the prognostic value of AMH is limited due to the relatively small number of patients with LVH after the electrocardiogram of the AMI, or possibly due to patient selection bias. The authors conducted a prospective study of 4720 consecutive AMIs to assess the prognostic significance of LVH with an electrocardiogram. Methods The subjects were AMI in an intensive care unit (CCU) at 13 hospitals between July 1981 and August 1983
