Conflicting trial results advise against routine GH use in HF; leaves open whether targeting GH resistance could improve outcomes.
Does growth hormone therapy improve cardiac function and exercise tolerance in patients with heart failure?
While the GH/IGF-1 axis plays a key role in cardiac regulation, clinical evidence for growth hormone supplementation in heart failure remains conflicting, highlighting the need to better understand GH resistance in this population.
