Heart radiation: a new hope for failing hearts?
NCT ID NCT06661876
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if a single low-dose radiation treatment to the whole heart can improve heart function in people with advanced heart failure. About 40 adults with severe heart failure who are not eligible for a heart transplant will receive this treatment. The goal is to see if it can boost the heart's pumping ability by at least 5% over six months, while keeping side effects low.
