Late heart attack intervention: helpful or not?
NCT ID NCT02445885
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 150 patients who had a heart attack 12 to 36 hours earlier. Researchers wanted to see if opening the blocked artery right away was better than waiting a few days. They used MRI scans to measure heart muscle damage and function.
