First seen Feb 18, 2026 · Last updated Jun 22, 2026 · Updated 18 times
Summary
This study tests whether relaxing before heart surgery using virtual reality, nature sounds, or binaural beats can reduce stress and prevent postoperative confusion (delirium) and memory decline. About 125 adults having elective heart surgery will be randomly assigned to one of these relaxation methods or standard care. The goal is to see if a simple, non-drug intervention can protect mental function after a major operation.
