Ghrelin treatment improved left ventricular function, increased lean body mass, and improved exercise capacity in heart failure — addressing both the cardiac dysfunction and the dangerous wasting that accompanies it.
Heart + body fixedGhrelin simultaneously improved cardiac function (LVEF) and reversed muscle wasting (lean mass) — addressing both halves of the heart failure-cachexia spiral
What the researchers found
Ghrelin treatment improved LVEF, increased lean body mass, enhanced exercise capacity, and reduced neurohormonal activation in heart failure, simultaneously addressing cardiac dysfunction and cachexia.
Why it matters
Cardiac cachexia is a death sentence — patients who develop it have dramatically worse survival. Ghrelin is the first agent to simultaneously improve heart function AND reverse the wasting.
How the study worked
Review of ghrelin effects on cardiac function, body composition, exercise capacity, and neurohormonal status in heart failure models and early clinical studies.
What this study cannot tell us
Review of mostly small studies. Large randomized trials needed. Whether ghrelin benefits are sustained long-term is unknown.
How to read the evidence
Moderate evidence from a review covering preclinical and early clinical heart failure data with multiple complementary endpoints.
When this study was published
Published in 2003. Ghrelin's cardiac cachexia benefits have been confirmed in subsequent clinical studies.
The bigger picture
Heart failure treatment has focused on pumping function and neurohormones. Ghrelin adds muscle preservation and appetite improvement — the missing pieces for the sickest patients.
Questions still open
- Should ghrelin be given to all heart failure patients with cachexia?
- Does lean mass improvement predict survival benefit?
- Can ghrelin be combined with current heart failure drugs?
