Sleep apnea treatment may help blood pressure, especially in the very sleepy
NCT ID NCT07497412
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether treating obstructive sleep apnea (OSA) with a breathing device (CPAP) lowers blood pressure more in people who are very sleepy compared to those who are not. Researchers will analyze data from about 10,000 adults with OSA from previous studies. The goal is to understand how sleepiness affects the heart benefits of CPAP therapy.
