摘要
缺血再灌注(ischemia reperfusion,IR)损伤是急性心肌梗死(acute myocardial infarction,AMI)重要的病理机制,是组织对缺血后血液灌注恢复的固有反应,增加了AMI的病死率和并发症。这是一个复杂的过程,包括在细胞内和细胞外环境中发生的多种机制,在这个过程中大部分机制是由活性氧(reactive oxygen species,ROS)介导的。对于IR损伤,寻找一个心脏保护剂和抗氧化剂来调节ROS浓度,进行预处理,对改善心脏功能和延缓心肌坏死具有非常重要的临床意义。本文就ROS在AMI再灌注损伤中的机制及信号靶点予以阐述,为临床防治心肌梗死再灌注损伤提供新的思路和方法。
