Mitophagy in cardiovascular diseases: molecular mechanisms, pathogenesis, and treatment

Trends Mol Med. 2022 Oct;28(10):836-849. doi: 10.1016/j.molmed.2022.06.007. Epub 2022 Jul 22.


With the growing prevalence of cardiovascular disease (CVD), there is an urgent need to explore non-conventional therapeutic measures to alleviate the burden of CVD on global healthcare. Mitochondrial injury plays a cardinal role in the pathogenesis of CVD. Mitochondrial dynamics and mitophagy are essential machineries that govern mitochondrial health in cardiomyocytes in physiological and pathophysiological settings. However, with the onset and progression of CVD, homeostasis of mitophagy is disturbed through largely unknown pathological mechanisms, causing mitochondrial damage and ultimately cardiomyocyte death. In this review we decipher the dual regulatory role of mitophagy in CVD pathogenesis, summarize controversies in mitophagy, and highlight recently identified compounds capable of modulating mitophagy. We share our perspectives on future mitophagy research directions in the context of CVD.

Keywords: cardiovascular disease; heart failure; mitophagy; mitophagy inducers; myocardial infarction; therapeutics.
