NCT ID NCT07315399

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

Summary

This study looks at how low oxygen levels during sleep (from obstructive sleep apnea) are connected to problems in the tiny blood vessels of the heart. Researchers will follow 560 adults with suspected heart issues to see if sleep apnea patterns can predict future heart events like heart attacks. The goal is to find better ways to identify heart risks early.
