摘要:

心肌缺血-再灌注损伤(ischemia reperfusion injury,IRI)是指在缺血心肌恢复血流灌注后,细胞代谢功能障碍和结构破坏反而加重的现象,并且伴随有以炎症细胞浸润和细胞因子产生为特征的炎症反应。已经证实,再灌注诱发的炎症反应及其介质可加重心肌缺血-再灌注损伤,而调控炎症反应则可减轻心肌缺血-再灌注损伤。本文就炎症反应在心肌缺血-再灌注损伤发生机制中的作用进行综述。

Abstract:

Myocardial ischemia reperfusion injury (IRI) is defined as myocardial injury caused by the restoration of coronary blood flow after an ischemic epsiode, which leads to severe myocyte metabolic derangements and ultrastructural impairment. The injury also triggers the activation of an inflammatory cascade evidenced by neutrophils accumulating and inflammatory mediators releasing. It has been identified that reperfusion-induced inflammation and excessive production of cytokines can promote myocardial damage during ischemia and reperfusion. Thus modulating the inflammatory response at the onset of reperfusion may represent a potent therapeutic strategy to attenuate the myocardial IRI. Here, we review current advances that the inflammatory response plays an important role in myocardial IRI.

Key words: ischemia reperfusion injury; inflammatory response; reactive oxygen species; cytokines
