Association of LDL cholesterol and Carotid Atherosclerosis in Menopausal women affected by Metabolic Syndrome

Background and aim: The metabolic syndrome is a highly prevalent condition associated with cardiovascular disease. However, the contribution of LDL to cardiovascular risk is not estimated since it is not part of ATP III criteria. Methods and results: This is an observational study evaluating the association between metabolic syndrome and carotid atherosclerosis, according to LDL cholesterol levels. Two hundred and sixty-five menopausal women were consecutively enrolled, they all underwent clinical examination, biochemical characterization and ultrasound evaluation. In particular, carotid atherosclerosis, a well known marker of cardiovascular disease, was evaluated. Women affected by cardiovascular disease were excluded from the study. The metabolic syndrome was found strongly associated with carotid atherosclerosis in our study population. In individuals with normal or near normal LDL, the incidence of carotid atherosclerosis was significantly lower than in subject with high LDL. A high plasma LDL concentration was independently associated with carotid atherosclerosis (pZ0.026) among women with the metabolic syndrome. Conclusions: High LDL cholesterol levels are associated with carotid atherosclerosis in menopausal women with the metabolic syndrome.
