对5 0例老年2型糖尿病合并急性心肌梗塞病人(DM -AMI组)和按一般情况及梗塞部位配对的无DM的AMI病人5 0例(NDM -AMI组)进行比较研究。结果显示:两组的肌酸磷酸肌酶(CPK)峰值、心电图QRS记分均无显著性差异。但DM -AMI组住院期间的死亡率及严重心脏事件的发生率均高于NDM -AMI组,梗塞后6个月时的左室舒张末容量(LVEDV)及收缩末容量(LVESV)均显著高于NDM -AMI组,而左室射血分数(LVEF)则明显低于NDM -AMI组,提示老年2型糖尿病合并急性心肌梗塞病人左心功能及心梗严重程度均较NDM -AMI者差,可能和合并DM性心肌病有关。
Fifty cases of elderly patients with type 2 diabetes mellitus complicated with acute myocardial infarction (DM-AMI group) and 50 cases of non-DM AMI patients (NDM-AMI group) paired with normal and infarcted patients were compared. The results showed that there was no significant difference between the two groups in peak creatine phosphokinase (CPK) and ECG QRS score. However, the in-hospital mortality and the incidence of serious cardiac events in DM-AMI group were significantly higher than those in NDM-AMI group. LVEDV and LVESV at 6 months after infarction were significantly higher In NDM-AMI group, and left ventricular ejection fraction (LVEF) was significantly lower than NDM-AMI group, suggesting that elderly patients with type 2 diabetes mellitus and acute myocardial infarction patients with left heart function and myocardial infarction severity were worse than NDM-AMI, May be associated with the merger of DM cardiomyopathy.
