Could a simple scan unlock better heart treatment?
NCT ID NCT05776212
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new PET scan technique to better track heart damage in people with a condition called ATTR-CM, a progressive heart muscle disease. Researchers will scan 140 participants to see if the imaging can show how well treatments are working. The goal is to improve monitoring and help doctors choose the best therapies for each patient.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 18F-fluoride PET scan (imaging tracer)
- What this could lead to
- If successful, this imaging technique could help doctors see how well treatments are working for ATTR-CM heart disease, leading to more personalized and cost-effective care.
- What could go wrong
- This is an early-stage imaging study, not a treatment trial. The new scan method may not prove accurate enough to replace current monitoring, and results may not apply to all patients.
