Summary

Chronic coronary syndrome (CCS) is the leading cause of death in women in the most developed regions of Brazil. The primary etiopathogenic mechanism is the process of atherosclerosis. A healthy diet rich in fruits and vegetables is associated with a lower incidence of CCS. The higher consumption of these foods promotes greater availability of phenolic compounds, and the higher intake of these compounds is one of the main hypotheses for vascular health. Quercetin, a phenolic compound, is the most abundant natural antioxidant belonging to the group of flavonoids. Quercetin improves lipoprotein metabolism, has an antioxidant capacity, produces vasodilating substances in the vascular endothelium, and reduces platelet aggregability. Likewise, statins are medications known to reduce cardiovascular events in women with CCS by reducing serum LDL-cholesterol levels and, to a lesser extent, by possible pleiotropic effects. In turn, SIRT1 is one of the 7 classes of proteins. It mediates various metabolic pathways in response to nutritional stimuli, particularly for caloric restriction and phenolic compounds, as well as coordinating the production and secretion of important hormones. However, the impact of quercetin supplementation and statin administration on serum endogenous estrogen levels is unknown
