Ketones in Heart Failure With Reduced Ejection Fraction
United States25 participantsStarted 2024-03-06
Plain-language summary
The purpose of this study is to understand the effects of a ketone drink on exercise capacity and other cardiovascular parameters in patients with heart failure. In heart failure, patients are limited in their ability to do all the things they want to do, and exercise as much as they would like, due to becoming tired and short of breath early. There may be several reasons why these symptoms occur. This study is assessing whether the ketone drink can improve these symptoms. This drink has been given status by Food and Drug Administration as "generally regarded as safe".
The use of DeltaG in this study is experimental. DeltaG has not been approved by the Food and Drug Administration (FDA) for the use being evaluated in this study.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria
. Stable cardiovascular medical therapy for 2 weeks
. Participants will be required to have heart failure with reduced ejection fraction (left ventricular EF \</= 45%) and New York Heart Association (NYHA) class II or III symptoms. In cases of ambiguity of functional status, reduced peak VO2 (\<85% predicted VO2) at the baseline visit can be used to confirm reduced exercise tolerance.
Exclusion criteria
. Intentional ketogenic diet in the last week
. Cirrhosis or significant alcohol consumption
. Contraindications to stress testing, conditions that limit exercise, and other clinically-significant causes of exertional limitation (claudication with peripheral artery disease, atrial fibrillation and heart rate \>110 at rest, systolic blood pressure\>180 mmHg or diastolic blood pressure\>110 mmHg, infiltrative/hypertrophic cardiomyopathy, clinically significant pericardial disease, joint or neuromuscular disease that precludes exercise, acute coronary syndrome within the last 2 months, estimated glomerular filtration rate\<20 mL/min/1.73 m2, and hemoglobin \< 9 mg/dL).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
