Hormonal Replacement Therapy in Heart Failure: Focus on Growth Hormone and Testosterone.

A growing body of evidence led to the hypothesis that heart failure (HF) could be considered a multiple hormone deficiency syndrome.

This article appraises the current evidence regarding growth hormone and testosterone deficiencies in HF and reviews novel findings about the treatment of these conditions in HF.
