Heart rate changes during sleep in severe sleep apnea
Part of Brain & nervous system, Lungs & breathing clinical trials.
This study looks at how your heart rate changes during sleep in people with severe sleep apnea compared to healthy people. It uses a simple overnight recording to measure your nervous system activity.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must either have severe sleep apnea (AHI > 30) or be a healthy person with no sleep problems.
- If you are healthy, you cannot have any sleep disorder, and you must score low on sleepiness and sleep quality tests.
- You cannot have a heart rhythm problem or a brain/psychiatric condition that affects your nervous system.
- You must be willing to have a sleep study (polysomnography) that records your heart and brain activity.
- You must be able to understand the study and give your consent.

This study will collect information from people with suspected sleep apnea who feel very sleepy during the day. If you are 18 or older and about to have a sleep study, you may be able to help researchers learn more about this condition.
This study looks at how sleep apnea affects your heart and blood vessels over time. It uses a sleep study and heart tests to see if certain measurements can predict heart health changes.
This trial uses a specialized brain scan (MRI) to study people with severe obstructive sleep apnea who are not using CPAP. It also compares them with people who do not have sleep apnea to understand how brain function differs.
This study is looking at a specific sleep-related condition (obstructive sleep apnea) in adults whose blood pressure is not high, and how their blood pressure rhythm changes over the day. If you have sleep apnea, participating could help researchers understand patterns that may affect long-term health.
This study tests whether a simple heart-rate measurement can help detect obstructive sleep apnea (a breathing condition during sleep) in people with high blood pressure. The goal is to find an easier way to screen for sleep apnea, which often goes undiagnosed but can worsen heart health.
This study looks for a biological marker of severe daytime sleepiness in people with severe obstructive sleep apnea who haven't started breathing machine treatment yet. It may help doctors better understand and treat sleepiness in the future.
