U.S., Nov. 4 -- ClinicalTrials.gov registry received information related to the study (NCT07913269) titled 'Heart and Brain Blood Flow in Obstructive Sleep Apnea' on Oct. 28.
Brief Summary: Obstructive sleep apnea causes repeated pauses in breathing during sleep. Breathing efforts against an occluded airway may change how blood flows through the heart and how blood drains from the brain.
This study will examine these changes in 25 adults with severe obstructive sleep apnea and 25 adults without sleep apnea, aged 18 to 65 years. Participants will attend a screening visit and one magnetic resonance imaging (MRI) visit. MRI will measure blood flow in major vessels in the chest, neck and brain at rest and during brief, standardized breathing ...
