缺血预适应与非Q波心肌梗塞的关系(附78例分析)

对78例心肌梗塞患者按梗塞前有无心肌缺血性心绞痛分为缺血预适应组（IP）和无缺血预适应组（P）两组。并根据病程中有无异常Q波发生，心肌酶谱峰值均值作对照分析。结果表明：P组Q波心肌梗塞的发生率明显高于IP组；心肌酶谱峰值均值IP组则明显低于P组。故认为心肌缺血预适应作用限制了梗塞面积的扩大、非Q波心肌梗塞发生率高，心肌酶谱峰值均值偏低，临床经过相对轻缓。

NON-Q WAVE MYOCARDIAL INFARCTION AND ISCHEMIA PRECONDITIONING

To investigate the clinical influence of ischemia preconditioning to acute myocardial infarction, 78 patients with acute myocardial infarction were divided into two groups (IP and P) based onwhether they had angina of myocardial ischemia before AMI or not - The average value of the peak of myocardial enzyme and the incidence of abnormal Q wave, left ventricular failure and disrhythmia were compared between IP and P groups. In group IP the incidence (70 % ) of NQMI was much higher than that ingroup P (18. 75 % ), and in general the clinical manifestations were more moderate than those in group P.There are two aspects showing the effect of ischemia preconditioning on AMI: to restrict the area extensionof AMI and to modify the clinical process of AMI.
