GH-releasing peptides improved cardiac dysfunction, reversed cachexia (muscle wasting), suppressed stress hormones, and reduced cardiomyocyte apoptosis in heart failure — demonstrating quadruple cardiac benefit.
Key findingGH-releasing peptides in heart failure models improved cardiac contractility, reversed cachexia, suppressed stress hormones (norepinephrine, cortisol)
What the researchers found
GH-releasing peptides in heart failure models improved cardiac contractility, reversed cachexia, suppressed stress hormones (norepinephrine, cortisol), and reduced cardiomyocyte apoptosis — quadruple mechanism benefit addressing four major heart failure components.
