Can a diabetes drug boost heart fuel? new study investigates
NCT ID NCT06229678
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how SGLT2 inhibitors, a type of diabetes medicine, change energy levels in the heart and muscles. Researchers will measure key energy molecules in 71 adults with type 2 diabetes and heart failure. The goal is to understand how these drugs work, not to test a new treatment.
