Official title
Sleep and Circadian Mechanisms Contributing to Nocturnal Non-dipping Blood Pressure
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will be the first to distinguish the relative contributions of sleep, circadian and behavioral mechanisms to the non-dipping BP profile in Black adults and will lay the groundwork for optimizing therapies dependent on mechanisms, such as targeting sleep, targeting circadian rhythmicity, or targeting behaviors, and raising the possibility that ideal therapy for hypertension (HTN) may differ by race. This research will ultimately help to improve health and survival in black populations with HTN.
