First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether giving inhaled nitric oxide during heart surgery can prevent acute kidney injury (AKI) in high-risk patients. AKI is a common and serious complication after heart surgery with no approved prevention. The trial will include 330 adults undergoing elective heart surgery with a heart-lung machine. Participants will receive either nitric oxide gas or a placebo through their breathing circuit during surgery, and kidney function will be monitored for 90 days after.
