心肌缺血预适应对急性心肌梗塞的影响

分析急性前壁或前壁合并下壁，高侧壁心肌梗塞１０５例病人缺血预适应对心肌梗塞的影响。心肌梗塞前有预缺血者６１例，无预缺血者４４例。结果显示：Ｂ组患者心肌酶峰值，梗塞面积及左室功能，病死率明显高于Ａ组，差别均有显著性，提示心肌梗塞前缺血对心肌具有一定的保护作用。

The effect of ischemic preconditioning on acute myocardial infarction

we analyzed the clinical datd of 105 cases of acute anterior myocardial infarction or anterior with inferior,lateral infarction (78 male,36 female).Sixty-one cases (group A ) had ischemic manifestations perior to myocardial infarction,while forty four (group B) did not have.Our date showed that the clinical features in group B were quite different as compared with those in group A:Higher peak level of serum cardiac enzymes,larger infarct size (QRS scoring),poorer cardiac function and higher mortality rate in 4 weeks.The difference between the two groups is statistically significant.Ischemic preconditioning have a protective effect on myocardialum.
