Autophagy contributes to the maintenance of intracellular homeostasis in most cells of
cardiovascular origin, including cardiomyocytes, endothelial cells, and arterial smooth
muscle cells. Mitophagy is an autophagic response that specifically targets damaged, and
hence potentially cytotoxic, mitochondria. As these organelles occupy a critical position in
the bioenergetics of the cardiovascular system, mitophagy is particularly important for

Autophagy contributes to the maintenance of intracellular homeostasis in most cells of cardiovascular origin, including cardiomyocytes, endothelial cells, and arterial smooth muscle cells. Mitophagy is an autophagic response that specifically targets damaged, and hence potentially cytotoxic, mitochondria. As these organelles occupy a critical position in the bioenergetics of the cardiovascular system, mitophagy is particularly important for cardiovascular homeostasis in health and disease. Consistent with this notion, genetic defects in autophagy or mitophagy have been shown to exacerbate the propensity of laboratory animals to spontaneously develop cardiodegenerative disorders. Moreover, pharmacological or genetic maneuvers that alter the autophagic or mitophagic flux have been shown to influence disease outcome in rodent models of several cardiovascular conditions, such as myocardial infarction, various types of cardiomyopathy, and atherosclerosis. In this review, we discuss the intimate connection between autophagy, mitophagy, and cardiovascular disorders.
