Mitochondria, as the guardians of cells, have complex physiological functions in living organisms. Mitochondrial autophagy, as a selective autophagy method, plays a crucial role in clearing damaged mitochondria, maintaining the quantity and function of mitochondria, and so on. After myocardial infarction, myocardial cells undergo ischemia and reperfusion injury, accompanied by abnormal mitochondrial function and an increase in the number, leading to the formation of myocardial fibrosis. The activation of mitochondrial autophagy has potential therapeutic value for im-proving myocardial injury and fibrosis. This article will summarize the specific pathways through which mitochondrial autophagy improves myocardial fibrosis after myocardial infarction, and comprehensively elaborate on the research progress of traditional Chinese medicine intervention in mitochondrial autophagy, in order to provide more effective strategies for the clinical treatment of myocardial fibrosis after myocardial infarction

线粒体作为细胞"守护者"，在生物体中具有复杂的生理功能。线粒体自噬作为一种选择性的自噬方式，在清除损伤的线粒体、维持线粒体的数量及功能等方面起着关键的作用。心肌细胞在心肌梗死后会经历缺血和再灌注损伤，并伴随着线粒体功能的异常及数目的增多，导致心肌纤维化的形成。线粒体自噬的激活对于改善心肌损伤和心肌纤维化具有潜在的治疗价值。本文对线粒体自噬在改善心肌梗死后心肌纤维化具体通路的作用机制进行总结，以及中医药干预线粒体自噬的相关研究进展进行综合阐述，以期为心肌梗死后心肌纤维化的临床治疗提供更为有效的策略。
