Abstrakt: Background: It is known that the association between LDL-cholesterol (LDL-C) and cardiovascular morbidity and mortality in the elderly is controversial. The aim of this study was to investigate this issue using carotid intima-media thickness as a marker of cardiovascular disease.
Methods: Women aged 35-79 years were consecutively enrolled in the study. They underwent a questionnaire to assess cardiovascular disease, a clinical examination to assess blood pressure and anthropometric variables, a biochemical evaluation of lipid profile and glucose, and an ultrasound evaluation of carotid arteries. The study population was divided into two age groups (≤65 years and >65 years), and each group was then divided into two subgroups according to LDL-C level (normal and high). A Student's t-test was used to compare mean values between groups, and a chi square test was used to compare the prevalence of carotid atherosclerosis.
Results: A lack of association between LDL-C and carotid intima-media thickness was observed in subjects aged >65 years, with the intima-media thickness average being similar between those with and without high LDL-C. Conversely, a significant difference in carotid intima-media thickness was observed among adults with and without high LDL-C level.
Conclusions: Our findings, similar to those obtained in other epidemiological studies, provide the rationale for revising the use of statins in elderly women without cardiovascular disease.
