First seen Jan 09, 2026 · Last updated May 23, 2026 · Updated 18 times

Summary

This study looks at how low oxygen levels during sleep from obstructive sleep apnea (OSA) may damage tiny blood vessels in the heart. Researchers will follow 560 adults with suspected heart issues to see if sleep apnea patterns predict future heart problems better than standard tests. The goal is to understand the connection, not to test a treatment.
