NCT ID NCT07422246
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study watches 100 heart surgery patients to learn why some develop serious gut issues. Researchers will track patients from hospital arrival to discharge, looking for early warning signs and risk factors. No new treatments are given—the goal is simply to better predict and diagnose these complications.
