Brief Summary:
Aim of the current study is to assess the cardiovascular effects of GH replacement therapy in patients with coexisting GHD and CHF

Condition or disease Intervention/treatment Phase
Heart Failure Growth Hormone Deficiency Drug: Human growth hormone Other: Placebo Phase 3

Detailed Description:

Multiple anabolic deficiencies are common in chronic heart failure (CHF) and identify subgroups of patients with higher mortality. Apart from CHF, GH deficiency (GHD) per se increases cardiovascular mortality in the general population and low IGF-1 levels in the general population predict the development of ischemic heart disease and CHF. GHD modifies cardiac size and function, through a reduction in both myocardial growth and cardiac performance. The investigators therefore completed 2 studies aimed at evaluating the clinical status, neurohormonal parameters, exercise capacity, vascular reactivity, and left ventricular architecture and function in patients with GHD and CHF, at baseline and after 6 months of GH replacement therapy. They subsequently extended the observation period up to 48 months. At 6-months, GH replacement therapy improved clinical status and exercise capacity, as shown by a significant reduction of the Minnesota living with heart failure questionnaire score, increased peak oxygen consumption and exercise duration, and flow mediated vasodilation of the brachial artery. No major adverse events were reported in the patients receiving GH.

However, the encouraging results of these studies are limited by the lack of a double-blind, placebo-controlled design, insofar as the investigators performed a randomized controlled, single-blind study.

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Treatment of Growth Hormone Deficiency Associated With Chronic Heart Failure: A Randomized, Double-Blind, Placebo-Controlled Study
Estimated Study Start Date : March 1, 2019
Estimated Primary Completion Date : March 1, 2022
Estimated Study Completion Date : March 1, 2022

Arm Intervention/treatment
Active Comparator: GHD Drug: Human growth hormone
Administration of growth hormone

Placebo Comparator: Placebo Other: Placebo
Administration of placebo

Primary Outcome Measures :
  1. Change of peak oxygen consumption (peak VO2) [ Time Frame: 1 year ]
    According to previous observations, the investigators set a target increase of peak VO2 in the treated arm at 3 ml/kg/min at the end of the study

Secondary Outcome Measures :
  1. Number of Hospitalizations [ Time Frame: 1 year ]
  2. End-systolic LV volumes [ Time Frame: 1 year ]
  3. NT-proBNP levels [ Time Frame: 1 year ]
  4. Quality of life score from the Minnesota Living with Heart Failure Questionnaire [ Time Frame: 1 year ]
    The questionnaire is comprised of 21 physical, emotional and socioeconomic questions that may adversely affect a patient's life. After receiving brief standardized instructions, the patient marks a 0 (lower valure) to 5 (upper value) scale to indicate how much each itemized adverse of heart failure has prevented the patient from living as he or she wanted to live during the past 4 weeks. The final score is calculated by sum.

  5. Evaluation of Endothelial function (flow-mediated vasodilation) [ Time Frame: 1 year ]
  6. Muscle strength (handgrip) [ Time Frame: 1 year ]
  7. Evaluation of the Levels of Endothelial Progenitor Cells (EPCs) [ Time Frame: 1 year ]
  8. Evaluation of the Levels of lymphocyte G protein-coupled receptor kinase (GRK)-2 [ Time Frame: 1 year ]
