NCT ID NCT04914663
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether a novel exercise program using both arms and legs can help protect the heart in women undergoing chemotherapy for breast cancer. Researchers will measure heart function and blood vessel health in 68 participants. The goal is to find a safe, practical way to prevent heart damage during cancer treatment.
