Increased epicardial adipose tissue volume in HIV-infected men and relationships to body composition and metabolic parameters

Abstract

Epicardial fat accumulation may have important clinical consequences, yet little is known regarding this depot in HIV patients. We compared epicardial fat volume in 78 HIV-infected men and 32 HIV-negative controls. Epicardial fat volume was higher in HIV-infected patients than that in controls (P = 0.04). In HIV patients, epicardial fat volume was strongly associated with visceral adipose tissue area (ρ = 0.76, P < 0.0001), fasting glucose (ρ = 0.41, P = 0.001) and insulin (ρ = 0.44, P = 0.0003). Relationships with glucose and insulin remained significant controlling for age, race, BMI, adiponectin, visceral adipose tissue and antiretroviral therapy. Epicardial fat may be an important fat depot in HIV-infected patients.
