Sleep Apnea, ObstructiveOSASNCT03075787
Cardiovascular Variability and Heart Rate Response Associated With Obstructive Sleep Apnea
An observational study of Sleep Apnea, Obstructive, run by Centre Hospitalier Universitaire de Saint Etienne at 1 site in France.
Trial summary
Obstructive sleep apnea is often associated with microarousals and a stimulation of the sympathetic nervous system. The knowledge of this autonomic activation may help understanding the increase of cardiac risk observed in elderly. Read more about this study

About this study
Obstructive sleep apnea is often associated with microarousals and a stimulation of the sympathetic nervous system. The knowledge of this autonomic activation may help understanding the increase of cardiac risk observed in elderly. The aim of the study is to evaluate the relationship between obstructive sleep apnea severity, age, gender and heart rate response associated with obstructive sleep apnea. Drug-free patients diagnosed with obstructive sleep apneas were included. Clinical data and 24-h polysomnography recordings were analyzed.

Questions about this trial
What is this clinical trial studying?
An observational study of Sleep Apnea, Obstructive, run by Centre Hospitalier Universitaire de Saint Etienne at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 6 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Amplitude of heart rate response associated with obstructive sleep apneas (time frame: At diagnosis). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Jul 2017.
