Six-months of recombinant human GH therapy in patients with ischemic cardiac failure.

Growth hormone therapy in patients with idiopathic dilated cardiomyopathy and ischemic cardiac failure has revealed varying effects on systolic function, probably related to the response in serum insulin-like growth factor I (IGF-I) levels. As diastolic function has not been studied thoroughly, we studied the effects of 6 months of recombinant human growth hormone (rh GH) treatment on systolic and diastolic function in patients with ischemic cardiac failure, using cardiovascular magnetic resonance (MR) imaging. Nineteen patients with ischemic cardiac failure (left ventricular ejection fraction (LVEF), <40%) were studied in a randomized trial. Nine patients received 6 months treatment with growth hormone (2 IU/day). Systolic and diastolic function were assessed at baseline and after 26 weeks by cardiovascular MR imaging. No differences were found in systolic and diastolic function between rh GH treated patients and controls. No change was observed in left ventricular mass index (LVMI), end-diastolic volume, end-systolic-volume and ejection fraction. The treated patients showed no clinical improvement. Six months of treatment with growth hormone therapy in ischemic cardiac failure has no favorable effects on LVMI, on systolic and diastolic function.
