About this study

Official title: Management of Sleep Apnoea Syndrome (SAS) in Patients With Vasovagal Syncope (VVS): a Protocol for the VVS-SAS Registry Study

This is a multi-centre, registry-based study whose primary objective is to evaluate the effect of treatment for sleep apnoea syndrome (SAS) on the number of syncope/malaise episodes in a population suffering from both idiopathic, recurrent vasovagal syncope/malaises and SAS.

Read the detailed description

Treatment for sleep apnoea syndrome includes continuous positive airway pressure (CPAP) or a mandibular advancement device (MAD). Additional routine follow-up includes 24 hour holter monitoring on a yearly basis, polysomnography on a yearly basis, multiple sleep latency tests, table tilt tests.

Being tested
Sleep apnea treatment
Medical subject headings
Syncope, Vasovagal, Sleep Apnea Syndromes

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Sleep apnea treatmentOther

    Sleep apnea treatment as decided according to routine practice. This may be Continuous positive airway pressure (CPAP) or wearing a mandibular advancement device (MAD).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in 6-month syncope rate

    Day 0 refers to the initiation of sleep apnea treatment. The baseline syncope rate refers to syncope events occurring between month -6 and day 0 (S_before). The post-treatment syncope rate refers to syncope events occurring between months +6 and +12(S_after). The change is rates is S_before minus S_after.

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?

Contact Vincent Puel, MD (+33 557810587, vpuel001@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in 6-month syncope rate (time frame: Month -6 to Day 0 versus Months +6 to +12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04294524, which also lists 1 linked publication.

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.
