The aim of the study is to compare the content of exosomes between two goups of 20 patients, with and without endothelial dysfucntion.~the endothelial function will be evaluated after polysomnography, on obese patients with OSA (AHI >15).
Evaluation of miRNA contained in exosomes in obese and OSA patients with endothelial dysfunction evaluated by digital plethysmography (ENDOPAT) compared to obese and OSA patients without endothelial dysfunction.
