Read our Heart Failure research guide →Phase 2 — Testing in a bigger group (up to a few hundred people) to see if the treatment actually works and is still safe.
This trial is testing a new imaging scan called 18F-mFBG that takes pictures of how well the nerves in your heart are working. Researchers believe this scan could help doctors better understand which heart failure patients are at higher risk for serious heart rhythm problems. The medication uses a small amount of radioactive tracer injected into your bloodstream to create detailed images of your heart's nerve activity.
Current heart imaging tests for nerve function have limitations—they depend heavily on the equipment used, can be expensive, and don't give doctors precise measurements. This trial is exploring whether the new treatment offers clearer, more reliable pictures to help doctors predict which patients might have dangerous heart rhythms in the future.

You will receive two imaging scans on the same day: one standard cardiac scan (using ) and the new scan being tested (using 18F-mFBG). Each scan involves receiving a small injection of radioactive tracer through an IV and then lying still under a special camera that takes pictures of your heart. The entire process typically takes a few hours, and you will not need to stay overnight.
