NCT ID NCT04766554
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether continuously measuring oxygen levels in the brain during heart bypass surgery can reduce memory and thinking problems after the operation. 326 older adults (age 60+) having planned heart surgery took part. Researchers compared standard care to care guided by a brain oxygen monitor to see if it improved cognitive recovery.
