Background and aims: Familial hypercholesterolemia (FH) is a common genetic disorder characterized by elevated blood cholesterol, increased prevalence of subclinical atherosclerosis and high risk of premature coronary heart disease. However, this risk is not explained solely by elevated LDL-cholesterol concentrations, and other factors may influence atherosclerosis development. There is evidence that increased adiposity may predispose to atherosclerosis in FH. Epicardial fat has been associated with subclinical coronary atherosclerosis in the general population. This study evaluated the association of epicardial fat (EFV) volume with the presence and extent of subclinical coronary atherosclerosis detected by computed tomography angiography in FH patients. Methods: Ninety-seven FH subjects (35% male, mean age 45 +/- 13 years, LDL-C 281 +/- 56 mg/dL, 67% with proven molecular defects) underwent computed tomography angiography and coronary artery calcium (CAC) scoring. EFV was measured in non-contrast images using a semi-automated method. Segment-stenosis score (SSS) and segment-involvement score (SIS) were calculated. Multivariate Poisson regression was utilized to assess an independent association of EFV with coronary atherosclerotic burden. Results: EFV was positively associated with age, body mass index, waist circumference, blood glucose, the presence of the metabolic syndrome components, but not with LDL-C. After adjusting for confounders and abdominal circumference, an independent association (shown as beta coefficients and 95% confidence intervals) of EVF with CAC scores [beta = 0.263 (0.234; 0.292), p = 0.000], SIS [beta = 0.304 (0.141; 0.465) p = 0.000] and SSS [beta = 0.296 (0.121; 0.471), p = 0.001] was found. Conclusions: In FH, EFV was independently associated with coronary atherosclerotic presence and severity. (C) 2016 Elsevier Ireland Ltd. All rights reserved.
