NCT ID NCT06398964

First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time

Summary

This study tested whether a 2-week course of a ketone drink could improve how the heart uses energy in 12 people with chronic heart failure. Researchers used PET scans to measure heart fuel consumption and efficiency. The goal was to understand if ketones could be a better energy source for failing hearts. This is early research, not a proven treatment.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

3-hydroxybutyrate (a ketone body) taken as a drink

What this could lead to

If successful, this could point toward a new way to improve heart energy efficiency in heart failure patients.

What could go wrong

This is a very small, early study with only 12 participants. It is designed to measure effects, not to prove a treatment works. Results may not apply to all heart failure patients.
