Growth Hormone as Biomarker in Heart Failure.

The impairment of growth hormone (GH)/insulin growth factor-1(IGF-1) plays a crucial role in chronic heart failure (CHF). Several studies have shown that patients affected by this condition display a more aggressive disease, with impaired functional capacity and poor outcomes. Interestingly, GH replacement therapy represents a possible future therapeutic option in CHF. In this review, the authors focus on the assessment of the main abnormalities in GH/IGF-1 axis in CHF, the underlying molecular background, and their impact on disease progression and outcomes.
