摘要 应用核素心室造影测定了68例急性心肌梗塞患者的左心功能。结果表明:左室射血分数(LVEF)≤30%。半年内死亡率为31.3%,而LVEF>30%组患者半年内无一例死亡。所有死亡患者的左室局部室壁运动异常的节段数>14。心肌梗塞部位与预后也有密切关系,前壁心肌梗塞组LVEF为40%,死亡率为12.8%,下壁梗塞组LVEF为51.1%。无一例死亡。 In order to evaluate the correlation between left ventricular function and the prognosis of acute myocardial infarction(AMI), 68 AMI patients were studied by radionuclide ventriculography and followed up for 14-42 days. The results demonstrated that in patients with AMI, if left ventricular ejection fraction (LVEF) was<30%, the mortality was 31.3% within 6 months after AMI. However, no death occurred in patients with LVEF≥30%. If the segmental number of regional wall motion abnormalities was>14, the mortality was 21.1%. The location of myocardial infarction was also related to the prognosis of AMI. In 39 cases of anterior wall Infarction, the mortality was 12. 8% and LVEF was 40.0%. While in cases with inferior wall infarction, LVEF was 51.1% with no death. So radionuclide ventriculography provides important prognostic informtion for patients with AMI.
