Abstract

Cardiovascular disease, (CVD) the leading cause of death worldwide, encompasses various heart and vascular disorders that significantly elevate morbidity and mortality rates. Sirtuin 1 (SIRT1), a NAD + dependent deacetylase, plays a key role in cardiovascular health and pathology by regulating fundamental processes such as endothelial function, oxidative stress, inflammation, senescence, metabolism, cardiac hypertrophy, and heart failure. Through these mechanisms, SIRT1 emerges as critical factor in the pathophysiology of CVDs, including heart failure, atherosclerosis, hypertension, and myocardial infarction. SIRT1 modulates several cellular pathways to regulate complex cellular processes associated with…
