Heart fat scans could unlock new heart failure treatments
NCT ID NCT07178145
First seen Jun 27, 2026 · Last updated Aug 12, 2026 · Updated 2 times
Summary
This study uses advanced MRI to measure the fat around the heart in people with a type of heart failure called HFpEF. Researchers want to see if the fat's composition, not just its amount, is linked to disease severity. They will also test if a diabetes drug called semaglutide changes this fat in a way that improves heart function. About 192 adults aged 18-90 with HFpEF risk factors will participate.
