Diet and exercise combo may boost muscle in heart failure patients
NCT ID NCT07595809
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a high-protein DASH diet, resistance exercise, or both can help people with heart failure and reduced ejection fraction maintain or increase muscle mass. About 100 adults over age 30 with stable heart failure will take part. The goal is to see if these lifestyle changes improve muscle strength, exercise ability, and quality of life.
