Major depressive disorder is associated with an increased risk for coronary artery disease. As epicardial adipose tissue (EAT), a metabolically active visceral fat depot, has been implicated in the pathogenesis of coronary artery disease, we hypothesize that EAT is increased in patients with major depression. Fat volumes were quantified by MRI and compared between groups. EAT was significantly elevated in patients with major depression and highest in a subgroup of patients with chronic depression. Therefore, increased EAT may contribute to the higher cardiovascular morbidity in depressed patients and particularly in the chronic form of this disease.
