Abstract

Objectives: This study sought to evaluate the efficacy and safety of long-term growth hormone (GH) replacement therapy in GH-deficient patients with chronic heart failure (CHF). Background: Recent evidence indicates that growth hormone deficiency (GHD) affects as many as 40% of patients with CHF, and short-term GH replacement causes functional benefit. Whether long-term GH replacement also affects CHF progression is unknown. Methods: The study is an extension of a previous randomized, controlled single-blind trial that screened 158 consecutive CHF patients (New York Heart Association classes II to IV) and identified 63 who had GHD by the growth hormone releasing hormone plus arginine test. Fifty-six patients were randomized to receive either GH therapy or standard CHF therapy. Patients were evaluated at baseline and after a 4-year follow-up. The primary endpoint was peak oxygen consumption (VO2). Secondary endpoints included left ventricular (LV) ejection fraction and volumes, serum amino terminal fragment of the pro-hormone brain-type natriuretic peptide, quality of life, and safety. Results: Seventeen patients in the GH group and 14 in the control group completed the study. In the GH group, peak VO2 improved over the 4-year follow-up. The treatment effect was 7.1 ± 0.7 ml/kg/min versus-1.8 ± 0.5 ml/kg/min in the GH and control groups, respectively. At 4 years, LV ejection fraction increased by 10 ± 3% in the GH group, whereas it decreased by 2 ± 5% in control patients. The treatment effect on LV end-systolic volume index was-22± 6 ml and 8 ± 3 ml/m2 in the GH and control groups, respectively (all p<0.001). No major adverse events were reported in the patients who received GH. Conclusions: Although this is a preliminary study, the finding suggests a new therapeutic approach to a large proportion of GHD patients with CHF.
