Official Title

Role of Growth Hormone in the Pathogenesis and Treatment of Cardiac Steatosis and Diastolic Dysfunction in HIV

Brief Summary

      Cardiac steatosis is increased among individuals with HIV, and may predispose to cardiac
      mechanical dysfunction and subsequent heart failure. The pathogenesis and treatment of
      cardiac steatosis is not well understood. The investigators have previously shown that
      perturbed growth hormone (GH) secretion in HIV contributes to ectopic fat accumulation in the
      viscera and the liver. Moreover, the investigators have found that augmentation of endogenous
      GH secretion with the FDA-approved medication tesamorelin reduces visceral and hepatic fat.
      In this longitudinal observational study, the investigators will examine patients with HIV
      and abdominal fat accumulation who either plan or do not plan to initiate tesamorelin
      prescribed clinically. The investigators hypothesize that blunted GH secretion in HIV is
      associated with cardiac steatosis. The investigators also hypothesize that use of tesamorelin
      for 6 months is associated with a reduction in intramyocardial fat and preserved cardiac
      function.
