Growth Hormone Deficiency in Chronic Heart Failure: A Preliminary Trial
|Heart Failure Growth Hormone Deficiency Ischemic Heart Disease||Drug: Somatotropin||Phase 2|
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Investigator)
Primary Purpose: Treatment
|Official Title:||Correction of Growth Hormone Deficiency in Patients With Chronic Heart Failure: a Randomized, Controlled, Single-blind Study|
- Peak VO2 [ Time Frame: 6 months ]changes in peak VO2
|Study Start Date:||December 2004|
|Study Completion Date:||November 2007|
|Primary Completion Date:||November 2007 (Final data collection date for primary outcome measure)|
Patients will receive 6 months of substitutive somatotropin (growth hormone) therapy at a dose of 0.012 mg/kg every second day, added to their background optimized CHF therapy
Subcutaneous Somatotropin (recombinant human Growth Hormone) 0.012 mg/kg every second day for 6 months
No Intervention: Placebo
PLacebo will be admistred with the same devices of GH, also on top of Optimal CHF treatment
To date, a wide range of alterations in the GH/IGF-1 axis have been described in patients with chronic heart failure (CHF): reductions in GH levels, reductions in IGF-1 and a pattern of peripheral resistance to GH, in particular in patients with severe heart failure and cardiac cachexia. Unpublished experience of our group support the concept that a considerable amount of CHF-patients have a coexisting Growth Hormone Deficiency (GHD), defined by current guidelines(GH stimulation test).
Our study hypothesis is that correction of GH deficiency in patients with chronic heart failure may exert a beneficial effect on their cardiac function and remodeling, performance status and quality-of-life.
Since this was a preliminary study, no sample size calculation was performed; treatment effects from were sought in left ventricular function (as assessed by cardiac MRI), cardiopulmonary exercise performance, clinical status, vascular reactivity, biochemistry and neurohumoral markers of disease (NT-proBNP).
