Heart MRI may help decide who needs a heart monitor after stroke
NCT ID NCT06047782
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether a special heart MRI can measure scarring in the left atrium, which might lead to atrial fibrillation. Researchers will enroll 100 people who had a stroke with no clear cause and who are already scheduled to get an implantable heart monitor. The goal is to see if the MRI results can predict who will actually develop atrial fibrillation, potentially reducing the need for monitors in some patients.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Cardiac MRI with contrast agent
- What this could lead to
- If successful, this could help doctors decide which stroke patients need an implantable heart monitor, potentially reducing unnecessary procedures and costs.
- What could go wrong
- This is a small pilot study with only 100 participants, so results may not apply to everyone. The MRI technique is still experimental and may not reliably predict atrial fibrillation.
