Molecular Profile of Cardiovascular Risk in Obstructive Sleep Apnea Patients: Personalized Predictive Model.
April 5, 2019 updated by: Ferran Barbe, Sociedad Española de Neumología y Cirugía Torácica
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).

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.
