Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The general objective is to evaluate the effect of continuous positive airway pressure (CPAP) treatment in patients with masked hypertension.

The secondary objectives are: i) To evaluate the prevalence of different circadian patterns of BP in ambulatory blood pressure monitoring (ABPM) (dipper / non-dipper); ii) To assess in these patients the relationship between compliance with CPAP treatment and the response to nocturnal BP; iii) To identify variables of the ABPM, and biomarkers that are related to the unfavourable pattern of nocturnal BP response in these patients treated with CPAP; iv) To evaluate the change in the profile of biomarkers with the treatment.

Methodology: Open, parallel, prospective, randomized and controlled study in which an ABPM will be performed in individuals with masked hypertension referred to the sleep unit and diagnosed of OSA (AHI≥ 30) without sleepiness (Epworth≤18).

A total of 64 subjects with OSA and masked hypertension will be recruited. It will be collected blood for the determination of biomarkers. Subsequently, they will be randomized to receive treatment with CPAP (32) or conservative treatment (32). After 3 months of initiation, ABPM and biological determinations will be repeated.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Recruitment: It will be recruited subjects with masked hypertension. For that, normotensive subjects (Blood pressure (BP)\<140/90mmHg in the office) referred to the sleep unit of the Hospital Santa Maria (Spain) who are diagnosed of severe OSA (AHI≥30) by a sleep study and who do not present significant somnolence (Epworth≤18) will be proposed to participate in the study. Then, it will be performed an ABPM during-24 hours, and those subjects with an abnormal ABPM results and normal BP in the office will be included, are those subjects called masked hypertensive.

Definition of the groups: Patients will be randomized to receive one of the following treatments:

1. CPAP: Patients who will receive CPAP treatment. The CPAP titration will be carried out with an automatic or manual CPAP according to usual clinical practice.
2. Conservative treatment: Patients who will receive conservative treatment based on hygienic-dietetic measures.

Randomization: It will be carried out with an automated platform

Duration of the treatment: All patients randomized to CPAP will begin treatment as soon as possible after randomization, and will continue treatment until the study ends (3 months).

Patients who interrupt treatment will be excluded from the study. ABPM and blood sample collection will be performed on all included patients at the beginning of the study and at 3 months under treatment (CPAP or conservative care).

Follow-up: All patients will be evaluated at the beginning of the study, at first month and at three months during the follow-up period.
