Mobile MRI vans hunt for silent heart failure in city dwellers
NCT ID NCT07185100
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will use a mobile MRI truck to screen 600 people in large German cities who have risk factors like diabetes, high blood pressure, or obesity but no heart failure symptoms. The goal is to find out how many have hidden (stage B) heart failure. Results will be compared to a similar rural study to see if city living makes a difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to a practical screening method to catch heart failure early in at-risk people, potentially preventing progression.
- What could go wrong
- This is an observational study, not a treatment trial. It will not directly improve health, and results may not apply to other populations or settings.
