Registry of patients with sleep apnea and daytime sleepiness

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to recruit 1000 patients suspected of having obstructive sleep apnea (OSA) who are referred to a sleep unit. Participants will undergo a sleep study for diagnosis, 24-hour ambulatory blood pressure monitoring, and complete quality of life questionnaires, including the Epworth test for daytime sleepiness. The study will evaluate OSA patients at baseline and follow up at 6, 12, and 24 months to assess treatment adherence, particularly for those using CPAP. Clinical variables and biological samples will also be collected to enhance understanding of the condition.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Patients who come to the sleep consultation for sleep study results for suspected OSA.
* Patients older than 18 years.
* Signature of the informed consent.

Exclusion Criteria:

* Psycho-physical inability to complete questionnaires.
* Presence of any previously diagnosed sleep disorder: narcolepsy, insomnia, sleep deprivation (less than 6h/day), regular use of medications hypnotics or sedatives (may be included if you only use a short-acting benzodiazepine or melatonin) and restless legs syndrome.
* Patients with \> 50% central apnea or presence of Cheyne-Stokes respiration (CSRsp).
* A medical history that may interfere with the objectives of the study or that in the judgment of the investigator compromises the conclusions.
* Any medical, social or geographical factor that may endanger the patient compliance. (eg, alcohol consumption (more than 80 g/day in men and more than 60 gr / day in women), absence of stable habitual residence, disorientation or non-compliance history).
* Any process, cardiovascular or not, that limits life expectancy to less than one year.
