Sirtuin-1 and Advanced Glycation End-products in Postmenopausal Women With Coronary Disease

Higher consumption of fruits and vegetables promote greater availability of phenolic compounds and these compounds were associated with vascular health. Quercetin, a phenolic compound, is the most abundant natural antioxidant belonging to the group of flavonoids. Quercetin improved lipoprotein metabolism, had antioxidant capacity, produced vasodilating substances in the vascular endothelium and reduced platelet aggregability. Likewise, statins are medications known to reduce cardiovascular events in women with coronary disease by reducing serum LDL-cholesterol. Therefore, a number of metabolic pathways are responsible for vascular health. The serum concentration and gene expression of sirtuin 1 (Sirt1) and RAGE soluble (sRAGE) are directly associated with vascular protection. This study will analyse the influence of atorvastatin and quercetin on serum concentrations and gene expression of Sirt1 and sRAGE in postmenopausal women with stable coronary artery disease.
