摘要

Ischemia-reperfusion injury (IR injury), produced by initial interruption and subsequent restoration of organ blood flow, is an important clinical dilemma accompanied by various cardiac reperfusion strategies following acute myocardial infarction (AMI). Although the restored blood flow is necessary for oxygen and nutrient supply, reperfusion often results in pathological sequelae leading to elevated ischemic damage. Among various theories postulated for IR injury including vascular leakage, oxidative stress, leukocyte entrapment, inflammation and apoptosis, mitochondrial dysfunction plays an essential role in mediating pathophysiological processes with recent evidence depicting a pivotal role for impaired mitophagy in mitochondrial injury. Given the critical role for mitophagy in mitochondrial quality control and the recent reports supporting a tie between mitophagy and IR injury, this review will revisit the contemporary understanding of mitophagy in the regulation of cardiac homeostasis and update recent progresses with regards to mitophagy and cardiac IR injury. We hope to establish a role for mitophagy as a potential therapeutic target in the management of IR injury.
