Fluid intake options for patients with heart failure

Official title: Liberal or Restricted Fluid Intake in Patients With Heart Failure: a Non-inferiority Randomized Controlled Trial

Run by Region Stockholm · NCT05931614 · Data updated 2026-11-12

This study tests whether allowing heart failure patients to drink as much fluid as they want is better for their health and well-being than limiting their fluid intake.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are individuals diagnosed with heart failure who can physically and cognitively participate in the trial.

Probably not a fit

Patients with reversible causes of heart failure or significant comorbidities that require specific fluid management may not benefit from this study.

What this trial studies

This study investigates the effects of unlimited versus restricted fluid intake in patients diagnosed with heart failure. It aims to evaluate how different fluid intake strategies impact symptoms, quality of life, and physical capacity in these patients. Given the lack of strong evidence supporting fluid restriction as a self-care method, this trial seeks to provide clarity on the best approach for managing fluid intake in heart failure patients. Participants will be monitored for their ability to manage their fluid intake and the resulting effects on their health outcomes.

Why it matters

Potential benefit: If successful, this study could lead to improved management strategies for heart failure patients, enhancing their quality of life and reducing hospital readmissions.

How similar studies have gone: Other studies have indicated the need for more evidence on fluid management in heart failure, suggesting this approach is novel and underexplored.
