本文介绍用多因素逐步回归法探讨影响急性心肌梗塞(AMI)病人预后的各种因素,从中筛选出对近期预后有显著影响的六项指标:心力衰竭;心源性休克;ST段抬高;房室传导阻滞;室内阻滞;严重室性心律失常。并建立了预测方程,经临床验证,存活与死亡预测符合率分别为95.35％和93.75％。作者认为应用多元预测式对判别AMI近期预后,简单、实用、准确。
This article describes the use of stepwise regression of multiple factors to explore the prognosis of acute myocardial infarction (AMI) patients with various factors, from which screening out the prognostic for the recent significant impact of the six indicators: heart failure; cardiogenic shock; ST elevation; Atrioventricular block; indoor block; severe ventricular arrhythmia. The prediction equation was established. The clinical validation showed that the coincidence rates of survival and death were 95.35% and 93.75% respectively. The authors believe that the application of multivariate predictive to determine the short-term prognosis of AMI, simple, practical and accurate.
