Efeitos de diferentes doses de rosuvastatina no metabolismo lipídico e dos carboidratos, morfometria do tecido adiposo e remodelamento cardíaco de camundongos C57BL/6 alimentados com dieta hiperlipídica

Abstract

There is a significant association between the prevalence of cardiovascular disease and metabolic syndrome. Evidence shows that obesity is associated with structural and functional changes in the heart. Statins can reduce the endogenous synthesis of cholesterol and are therefore used as an important tool against hypercholesterolemia in obese. The present work aims to study the effects of rosuvastatin in lipid and carbohydrate metabolism, adipose tissue morphometry and cardiac remodeling. In this work we studied the effects of rosuvastatin treatment on the body mass, insulin resistance, lipid profile, blood pressure, cardiac remodeling and structure and ultrastructural changes in the heart of the C57BL/6 male mice fed a high-fat diet. The rosuvastatin treatment reduced levels of blood lipids, improve insulin resistance, reduced blood pressure and body mass of high-fat mice. Furthermore, it attenuated cardiac remodelling, decreasing the interstitial and perivascular fibrosis, and maintained the integrity of mitochondrial morphology, with a lower production of UCP-2. Rosuvastatin had beneficial effects on cardiac changes induced by high-fat diet, as well as in mitochondrial morphology, thus controlled energy production to maintain cardiomyocyte integrity.
