Summary

This trial is looking at how a ketone drink can impact exercise capacity and other heart-related factors in patients with heart failure. Patients with heart failure often struggle with fatigue and shortness of breath, limiting

Who is the study for?
This trial is for people with heart failure who have a reduced ability of the heart to pump blood (ejection fraction of 45% or less) and experience moderate symptoms like getting tired or short of breath easily. They should be on stable heart medication for at least two weeks.
What is being tested?
The study is testing if a ketone drink, considered safe by the FDA but not yet approved for this use, can help improve exercise capacity and other heart-related functions in patients with heart failure.
What are the potential side effects?
Since the ketone ester drink has 'generally regarded as safe' status, significant side effects are not expected. However, potential risks may include gastrointestinal discomfort or allergic reactions.
