Abstract

Objective Nonalcoholic fatty liver disease (NAFLD) is a well-known contributor for the development of cardiovascular disease (CVD). We examined the influence of NAFLD and metabolic syndrome (MetS) on markers of subclinical atherosclerosis, including carotid intima-media thickness (CIMT), brachial-ankle pulse wave velocity (baPWV) and ankle-brachial pressure index (ABI), after adjusting for cardiometabolic risk factors. Design A cross-sectional study. Patients and measurements The association between NAFLD, MetS and markers of subclinical atherosclerosis was assessed in 955 participants without CVD using multiple logistic regression analysis after adjusting for multiple cardiometabolic risk variables. Results After adjusting for age and sex, CIMT and baPWV were found to be significantly correlated with multiple cardiometabolic risk variables, whereas ABI was only associated with obesity parameters. The prevalence of NAFLD differed significantly according to the presence of subclinical atherosclerosis as defined by both CIMT and baPWV (P = 0·004 and P = 0·007, respectively). After adjusting for potential confounding factors, NAFLD or MetS was not associated with subclinical atherosclerosis as defined by CIMT and baPWV. However, individuals with both NAFLD and MetS had a significantly higher risk of subclinical atherosclerosis as defined by CIMT (OR = 2·06, 95% CI = 1·13-3·74) or baPWV (OR = 2·64, 95% CI = 1·46-4·76) compared to normal subjects, even after adjusting for potential confounders. Conclusions The results show that NAFLD and MetS have a synergistic impact on the subclinical atherosclerosis, which suggests that individuals with both NAFLD and MetS should be strongly advised to engage in CVD prevention strategies.
