Summary

This study looked at 100 people who recently had a major heart attack to better understand blood clots that can form in the heart's main pumping chamber. Using special PET/MR scans, researchers tracked clot activity in the heart and brain over several months. The goal was to learn how these clots form, change, and dissolve, which could lead to better ways to prevent strokes and other complications.
