New scan peers inside heart cells to spot early trouble
NCT ID NCT03549559
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new imaging tracer called 11C-Martinostat that lights up a specific enzyme (histone deacetylase) in the heart during a PET-MRI scan. Researchers will compare enzyme activity in people with aortic stenosis or diabetes to healthy volunteers. The goal is to see if this scan can reveal early changes in heart muscle that might lead to better diagnosis of heart conditions.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 11C-Martinostat (a radioactive imaging tracer)
- What this could lead to
- If successful, this could lead to a new way to detect early heart disease by imaging enzyme activity, potentially improving diagnosis and monitoring.
- What could go wrong
- This is an early imaging study, not a treatment trial. The tracer may not reliably distinguish between groups, and results may not translate to clinical practice.
