NCT ID NCT03748082

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study was designed to test whether giving nitric oxide gas during heart surgery could help protect blood vessels in patients with pre-existing vessel problems. It was an add-on to a larger trial and planned to enroll adults having elective heart surgery with prolonged bypass. However, the study was withdrawn before any participants were enrolled, so no results are available.
