Heart hormone genes may explain diabetes risk in some people
NCT ID NCT05216042
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at how a heart hormone called atrial natriuretic peptide (ANP) affects metabolism and heart health. Researchers will test 200 adults with different genetic versions of ANP to see how their bodies respond to exercise and sugar. The goal is to understand why some people have lower ANP levels and higher risk for diabetes and heart disease.

- If successful, this study could reveal why some people are more prone to diabetes and heart disease, pointing toward personalized prevention strategies.
- What could go wrong
- This is an observational study, not a treatment trial. It may not lead to direct therapies, and results might not apply to everyone.
