通过对２０２例急性心肌梗塞患者的诊治和随访，应用ＣＯＸ回归模型的多因素生存分析的方法对其发生影响的多种变量进行分析。结果表明性别、房性早搏、舒张压和ＣＰＫ及ＭＢ的峰值是影响ＡＭＩ患者预后的独立变量。显示女性患者的预后较男性差；入院时的低舒张压和出现有房性早搏者预后差；低和高的ＣＰＫ及ＭＢ峰值的ＡＭＩ患者的预后差。认为通过早期对影响ＡＭＩ预后的独立变量因素的监测，对高危病人进行有效的综合处理，对改善ＡＭＩ患者的预后有益。
Through the diagnosis and follow-up of 202 patients with acute myocardial infarction, a variety of variables influencing them were analyzed by multivariate survival analysis of COX regression model. The results showed that gender, atrial premature beats, diastolic blood pressure and the peak of CPK and MB were the independent variables affecting the prognosis of patients with AMI. The prognosis of female patients was worse than that of men. The low diastolic blood pressure at admission was worse than that of patients with atrial premature beats. The prognosis of AMI patients with low and high CPK and MB was poor. It is believed that the effective comprehensive treatment of high-risk patients through the early monitoring of independent variable factors that affect the prognosis of AMI is beneficial to improve the prognosis of AMI patients.
