Diet and exercise plan to help people with heart failure and preserved heart function.

Official title: Dietary Intervention and Physical Activity in Patients With Heart Failure and Reduced Ejection Fraction

Run by Medical University of Silesia · NCT07595809 · Data updated 2026-11-12

This study tests whether a DASH-style, high-protein diet, resistance exercise, or both can help build muscle and improve fitness and quality of life in people with heart failure and reduced ejection fraction.

Is this trial a fit for you?

Likely a good fit

Adults over 30 with chronic heart failure, NYHA I–III, and left ventricular ejection fraction below 40%.

Probably not a fit

Patients with NYHA IV heart failure or significant comorbidities that limit participation may see little to no benefit.

What this trial studies

This randomized trial will evaluate the effects of dietary intervention based on the DASH diet with higher protein content, resistance training, and their combination on skeletal muscle mass, functional capacity, heart imaging, biomarkers, and quality of life in adults with heart failure and reduced ejection fraction. Participants will be assigned to one of the intervention arms to see which approach, or combination, yields the best improvements. The study is conducted at two sites in Poland and aims to provide evidence for non-drug strategies to support patients beyond standard medical therapy.

Why it matters

Potential benefit: If successful, participants may experience improved muscle mass, better exercise tolerance, and enhanced quality of life.

How similar studies have gone: Prior research suggests that nutrition and resistance exercise can positively affect muscle and function in heart failure, but results vary and this study adds randomized, combined-therapy data.
