|Abstract:||Osteoporosis and coronary heart disease (CHD) are very common conditions among elderly people, and both represent a public health concern due to their prognostic consequences. Osteoporosis and CHD share many risk factors and pathophysiological mechanisms, such as calcification pathways. Clinical evidence associates lower bone mass with cardiovascular diseases and endothelial dysfunction. Hence, this study aims to investigate whether bone mass density is associated with subclinical atherosclerosis and/or endothelial dysfunction in the very elderly. We performed a cross-sectional study of cohort enrolled individuals, ages 80 years or older (n = 208), who had never manifested cardiovascular diseases. Medical evaluation, blood tests, flow-mediated dilation (FMD), carotid intimal-media thickness (IMT), Dual Energy X-ray Absorptiometry (DEXA) and Coronary Calcium Score (CCS) were obtained. Odds Ratio (OR) was calculated by multivariate logistic regression models using CCS, FMD and IMT categories. Adjustments for covariates were done. Overall bone mass was independently and inversely associated with CCS categories [OR:1.68(1.16–8.85); p = 0.024] and IMT categories [OR:2.97(1.11–7.90); p = 0.030]. Conversely, overall bone mass was independent and directly associated with FMD categories [OR:2.73(1.36–70.39); p = 0.023]. This study indicates that overall bone mass is independently and inversely associated with subclinical atherosclerosis, endothelial dysfunction and thickness of carotid in the very elderly|
