Abstract: Epicardial Adipose Tissue (EAT) has been associated with adverse cardiovascular events in the general population. We studied the association of general adiposity measures (body mass index, waist circumference) and ectopic adipose tissue [visceral adipose tissue (VAT); liver fat (LF); EAT) with prevalent cardiovascular disease (CVD) (prior myocardial infarction, coronary revascularization, stroke, peripheral vascular disease] in 583 HIV-infected men. VAT, EAT, and LF (liver/spleen attenuation ratio < 1.1) were measured by computed tomography. Patients' mean age was 48.5 ± 8.1 years, prior CVD was present in 33 (5.7%) patients. Factors independently associated with CVD on multivariable analyses were age [incidence-rate ratio (IRR) = 1.07, 95% confidence interval (CI): 1.02 to 1.12], smoking (IRR = 2.70, 95% CI: 1.22 to 6.01), Center for Disease Control group C (IRR = 3.09, 95% CI: 1.41 to 6.76), EAT (IRR = 1.13, 95% CI: 1.04 to 1.24, per 10 cm3), LF (IRR = 1.17, 95% CI: 1.04 to 1.32), and VAT (IRR = 1.05, 95% CI: 1.00 to 1.10, per 10 cm3). Ectopic fat but not general adiposity measures were associated with prevalent CVD in men with HIV.
