New Approach in the Study of the Autonomic Nervous System Through Cardiac Variability in Sleep Apnea Syndrome.
This study aims to understand how severe sleep apnea impacts the natural changes in your heart's rhythm, particularly while you're asleep. We're comparing people who have severe sleep apnea with healthy individuals who don't have sleep problems. Our main goal is to find a new and simpler way to spot sleep apnea early on. We'll be looking carefully at heart rhythm during different stages of sleep, especially during REM sleep, when sleep apnea can be at its worst. By using smart computer programs (artificial intelligence), we hope to develop a reliable test that can be used more easily outside of a hospital setting, making it quicker and more convenient to diagnose sleep apnea.
At a glance
What is this study about?
This research is all about exploring how sleep apnea, a condition where your breathing repeatedly stops and starts during sleep, affects your heart. Your heart doesn't beat at a perfectly steady rate; it constantly adjusts, and these tiny changes are called 'cardiac variability' or 'heart rate variability'. Scientists believe that sleep apnea can disrupt these normal heart rhythm changes.
The main aim of this study is to compare these heart rhythm changes between two groups of people: those with severe sleep apnea and healthy individuals. We'll be using a special technique developed by the CIC-IT research group to measure these changes. We're particularly interested in what happens during REM sleep, as this can be a time when sleep apnea is most severe and puts the most stress on your body. After looking at REM sleep, we'll examine other sleep stages too.
Ultimately, the results of this study could lead to a brand new way of detecting sleep apnea. We hope to develop a reliable and easy-to-use screening method that uses artificial intelligence. This could mean that diagnosing sleep apnea might become simpler and more widely available, perhaps even allowing for testing outside of traditional sleep clinics. This could help more people get diagnosed and treated sooner.
Key takeaways
- Researchers are looking for a new way to spot sleep apnea early.
- The study focuses on how sleep apnea affects your heart's rhythm during sleep.
- It compares people with severe sleep apnea to healthy sleepers.
- Artificial intelligence will be used to develop a potential new test.
- The aim is a simpler, more accessible screening method for sleep apnea.
Who may be eligible?
To join this study, you need to be between 18 and 64 years old, and be able to give your informed consent. The study is open to both men and women.
There are two main groups of people we are looking for. One group includes healthy individuals who do not have any sleep problems. For this group, we're looking for people who generally sleep well and don't show signs of sleep disorders when answering questionnaires.
The second group is for people who have been diagnosed with severe obstructive sleep apnea, meaning their breathing effort repeatedly stops and starts over 30 times an hour during sleep. Individuals will not be able to participate if they have certain heart rhythm problems, neurological (brain or nerve) or psychiatric (mental health) conditions that might affect their body's automatic functions, or if they have other sleep disorders in addition to severe sleep apnea. Also, if you can't commit to the whole study or don't have social security coverage, you won't be able to take part.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you between 18 and 64 years old?
- Do you have severe sleep apnea OR are you a healthy person with no sleep problems?
- Do you NOT have heart rhythm problems, or certain brain/mental health conditions?
- Can you commit to taking part in the full study?
- Do you have social security coverage?
What does participation involve?
We don't have all the details about what your participation will involve in this summary, as the study description is brief. However, typically, studies like this often involve at least one night of sleep monitoring, which might include wearing sensors that track your brain activity, breathing, and heart rhythm while you sleep. You would likely visit a clinic for these assessments. There are no medications involved in this study. The total duration of your involvement isn't specified, but it often involves initial screening, the sleep study itself, and possibly follow-up to discuss results.

Common questions
What is sleep apnea?
Sleep apnea is a common condition where your breathing repeatedly stops and starts while you're asleep, usually for short periods.
What does 'cardiac variability' mean?
Cardiac variability refers to the natural, small changes in the time between your heartbeats. It's a sign of how well your heart can adapt.
What is REM sleep?
REM sleep is a stage of sleep when you dream most vividly. Breathing and heart rate can be more irregular during REM sleep than other stages.
Will I have to take any new medicines?
No, this study is about measuring your body's responses, not testing new medications.
How will this study help people?
By finding new ways to quickly and easily identify sleep apnea, this study could help more people get diagnosed and treated earlier.
