RecruitingDevice studyMicroRNAs as Biomarkers for Obstructive Sleep ApneaAlthough obstructive sleep apnea (OSA) is a common disorder, there are no blood biomarkers for identification and management of these patients. This project will study microRNAs in order to develop and validate blood biomarkers that are specific to OSA, useful for identification of cases with OSA, reflective of efficacy of therapy, and able to predict blood pressure response to treatment of OSA.
