1 概述缺血预处理现象在哺乳动物和人中广泛存在 ,预处理保护心肌的过程实际上是心肌细胞对继发性损伤耐受性的适应过程 ,它可以减少再灌注心律失常 ,减少心肌梗死面积 ,改善缺血后心肌的功能 ,减少心肌的能量消耗 ,延缓心肌超微结构的变化 ,减少血管内皮损伤。其如何对心肌产
1 Overview The phenomenon of ischemic preconditioning is widespread in mammals and humans. The process of preconditioning and protecting myocardium is in fact a process of cardiomyocyte adaptation to secondary injury tolerance, which can reduce reperfusion arrhythmia and reduce myocardial infarction Area, improve the function of ischemic myocardium, reduce the energy consumption of myocardium, delay the changes of myocardial ultrastructure and reduce the damage of vascular endothelial cells. How to produce myocardial
