Is this trial a fit for you?

Likely a good fit

Ideal candidates include individuals diagnosed with heart failure with preserved ejection fraction and a BMI of 27.5 kg/m² or higher.

Probably not a fit

Patients with contraindications to MRI or those with severe heart conditions may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates how weight loss impacts individuals with heart failure with preserved ejection fraction (HFpEF) who are overweight or obese. Participants will be randomly assigned to either a diet intervention or a control group receiving standard care. The study will assess various outcomes, including heart function, quality of life, and exercise capacity through a series of measurements such as echocardiograms, MRIs, and questionnaires. The study aims to determine if weight loss can improve heart shape and pumping efficiency in this patient population.

Why it matters

Potential benefit: If successful, this study could lead to improved heart function and quality of life for patients with HFpEF who are overweight or obese.

How similar studies have gone: Other studies have shown promising results in weight loss interventions for heart failure patients, suggesting potential for success in this approach.
