0044 The Circadian System Modulates Cardiovascular Responses To Standing Differently In People With Obstructive Sleep Apnea Compared To Healthy Controls.

[摘要] IntroductionAdverse cardiovascular (CV) events occur most commonly at ~9 AM in the general population, but ~3 AM in people with obstructive sleep apnea (OSA). Standing up after a night of sleep generates changes in blood pressure (BP) and heart rate (HR) and autonomic activation. We tested whether the CV reactivity to standing is different in OSA versus healthy controls (HC) across all phases of the circadian cycle.
