Massive US study reveals hidden bleeding complication after heart attacks
NCT ID NCT06162039
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This completed study looked at medical records from over 24,000 people across the United States who had a heart attack. The goal was to find out how often a specific complication called hemorrhagic myocardial infarction (bleeding inside the heart muscle) occurs. Researchers also tracked how many of these patients later developed heart failure or needed to be readmitted to the hospital. This is an observational study that does not test any new treatment.
