Abstract: Entropy is a natural process that affects all living cells, including senescence, an irreversible
physiological process that impairs cell homeostasis. Age is a significant factor in disease
development, and the pathogenesis of endothelial cell aging is multifactorial. Autophagy dysfunction
accelerates endothelial cell aging and cell death, while autophagy preserves endothelial
cell youthfulness through intracellular homeostasis and gene expression regulation. Sirt,
mTORC1, and AMPK are youthfulness genes that induce autophagy by inhibiting mTOR and
upregulating FIP200/Atg13/ULK1. Aged endothelial cells have decreased levels of Lamin B1,
γH2AX, Ki67, BrdU, PCNA, and SA β-Gal. Maintaining healthy young endothelial cells can
prevent most cardiovascular diseases. Autophagy targeting is a potential future therapeutic strategy
to modify endothelial cell age and potentially slow or reverse the aging process. This article
provides state-of-the-art research on the role of autophagy in endothelial cell aging. Hypothesizing
that autophagy dysregulation is associated with early endothelial cell dysfunction and further
clinical sequelae, including atherosclerosis formation, leading to various cardiovascular diseases.
