Abstract
Myocardial ischemia-reperfusion injury (MIRI) has a high incidence and is difficult to cure. Studies have shown that mitophagy is the key mechanism. This review systematically summarizes all documented herbal preparations and bioactive monomers targeting mitophagy for MIRI treatment, which may serve as a valuable reference for future research on herbal medicine-mediated mitophagy regulation. We conducted comprehensive literature searches in PubMed, Embase, Web of Science, and CNKI databases using the keywords "cardiovascular diseases," "mitophagy," "myocardial ischemia-reperfusion injury," "herbal medicine," "mechanism," and "therapeutic" for studies published within the last five years up to July 2025. Studies on herbal medicine interventions unrelated to mitophagy were excluded. Our analysis reveals that mitophagy plays a crucial role in attenuating the detrimental effects of MIRI. Furthermore, herbal medicine demonstrates therapeutic efficacy in maintaining homeostatic balance of mitophagy during MIRI. Herbal medicines can precisely regulate mitophagy via the PTEN-induced putative kinase 1 (PINK1)-parkin pathway, and modulate the expression of BCL2 interacting protein 3 (BNIP3), FUN14 domain-containing protein 1 (FUNDC1), NIP3-like protein X (NIX). Herbal medicines exert protective effects against MIRI through diverse mechanisms and signaling pathways by targeting mitophagy. While mitophagy represents a promising frontier for future cardiovascular research, current herbal medicine applications remain predominantly confined to animal and cellular models, with only limited clinical translation. The findings presented herein are anticipated to provide clinicians and cardiovascular researchers with valuable therapeutic strategies and novel research directions.
