Context: A reduced activity of the GH/IGF-I axis in chronic heart failure (CHF) has been described by several independent groups and is associated with poor clinical status and outcome. Objective: The aim of the current study was to investigate the prevalence of GH deficiency in a patient population with CHF and evaluate the cardiovascular effects of GH replacement therapy. Design and Setting: The randomized, single-blind, controlled trial was conducted at the Federico II University. Participants: One hundred fifty-eight patients with CHF, New York Heart Association class II-IV, underwent a GH stimulation test. Sixty-three patients satisfied the criteria for GH deficiency, and 56 of them were enrolled in the trial. Intervention: The treated group (n = 28) received GH at a replacement dose of 0.012 mg/kg every second day (∼2.5 IU). Main Outcomes Measures: Changes in physical performance and various cardiovascular indexes were measured. Results: GH replacement therapy improved quality of life score (from 46 ± 5 to 38 ± 4; P <0.01), increased peak oxygen uptake and exercise duration (from 12.9±.9 to 14.5±1 ml/kg · min and from 520 ± 36 to 586 ± 43 sec, respectively; P <0.01), and flow-mediated vasodilation (from 8.8 ± 1.3 to 12.7±1.2%;P
