What this trial studies

This study investigates the physiological effects of ketone esters on patients with heart failure by utilizing cardiac MRI for detailed imaging. Participants will be randomly assigned to receive either ketone esters or a placebo over a 12-week period. The primary goal is to assess changes in heart function and structure through advanced imaging techniques. This approach aims to provide insights into the potential therapeutic benefits of ketone esters in managing heart failure.

Who should consider this trial

Good fit: Ideal candidates for this study are patients diagnosed with heart failure and an ejection fraction of less than 40%.

Not a fit: Patients with claustrophobia or those with contraindicated implanted devices will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new dietary or therapeutic strategies for improving heart function in patients with heart failure.

How similar studies have performed: While the use of ketone esters in heart failure is a relatively novel approach, preliminary studies in related areas suggest potential benefits, though this specific application is less explored.
