About this study

Evaluation of anthropometric, clinical and biological profile in four groups that represents transversely the natural history of Obstructive Sleep Apnea (OSA) and its associated cardiovascular comorbidities: non-OSA, OSA without hypertension, OSA and with hypertension and OSA with a cardiovascular event (CVE).

Read the detailed description

Aims: The main objective of the study is to determine the risk profile associated with the development of cardiovascular (CV) disease in patients with OSA. To do this, by using genomic analysis tools, transcriptome and the analysis of protein markers are established the following objectives: 1) to determine differences in phenotypic profile (anthropometric, clinical, analytical and biological variables) from different populations: non-hypertensive patient with OSA, OSA hypertensive patient, OSA hypertensive patient who has developed a CV event and healthy subject. These four populations represent transversely the natural history of OSA. In this way the phenotype of the OSA patient and its relationship with risk of developing of CV disease will be defined. 2) To define the changes produced in these profiles after effective treatment with continuous positive airway pressure (CPAP). This approach allows to evaluate the different pathogenic pathways related to CV risk in patients with OSA. 3) To define a predictive model of cardiovascular risk and response to CPAP treatment, in patients with OSA. 4) To phenotype and define the different and segregated clusters of OSA patients whose recognition may improve prognostic predictions and guide therapeutic strategies Methodology: For ethical reasons a longitudinal study cannot be carried out to know history natural the disease (can not leave without treatment patients with OSA long term). We propose a transversal study in which will be include four populations that representing transversally the natural history of OSA (non-OSA individuals, non-hypertensive OSA patients, OSA patients with hypertension and hypertensive OSA patients who have developed a CV event). All the patients will be performed a general analysis, lipid profile and polysomnography. The expression profile of microRNAs associated with cardiovascular risk will be assessed in addition to the gene expression profile associated with arterial hypertension. The measurements are made at baseline and 6 months after effective treatment with CPAP. This methodological approach will contribute in the identification of OSA phenotype which could develop cardiovascular disease.

What is being measured

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

  1. Modeling the cardiovascular (CV) disease risk in patients with obstructive sleep apnea (OSA) through the analysis of the number and specific biomarkers.

    Anthropometric, clinical, analytical and biological variables characterization from different populations:non-OSA, OSA without hypertension, OSA with hypertension and OSA with a CV event. The evaluation of these variables will permit the characterization of the profile associated with CV disease in patients with OSA.

    Measured: Baseline

Secondary outcomes (2)
  1. Modeling the effect of the treatment with continuous positive airway pressure (CPAP) in patients with OSA with and without cardiovascular disease, through the analysis of the number and specific biomarkers.

    Anthropometric, clinical, analytical and biological variables characterization from different populations:non-OSA, OSA without hypertension, OSA with hypertension and OSA with a CV event. The evaluation of these variables changes after CPAP treatment will allow to characterize the effect of this treatment in biomarker related with CV disease

    Measured: After 6 months of follow-up

  2. Predictive model of cardiovascular risk

    Define a predictive model of cardiovascular risk and response to CPAP treatment, in patients with OSA.

    Measured: After 6 months of follow-up

Questions about this trial

What is this clinical trial studying?

An observational study of Obstructive Sleep Apnea and Hypertension, run by Sociedad Española de Neumología y Cirugía Torácica at 1 site in Spain.

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 2 inclusion and 4 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: finished, as of the sponsor's last update on 8 Apr 2019. 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 Spain. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Modeling the cardiovascular (CV) disease risk in patients with obstructive sleep apnea (OSA) through the analysis of the number and specific biomarkers. (time frame: Baseline). 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 8 Apr 2019.
