Obstructive Sleep Apnea (OSA) and Metabolic Syndrome: Role of Oxidative Stress

NCT00177892 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 76

No results posted yet for this study

Summary

The purpose of this study is to define the mechanism(s) through which Obstructive Sleep Apnea/Hypopnea (OSAH) promotes abnormal metabolic processes which characterize the metabolic syndrome. The investigators hypothesize that the sleep fragmentation and intermittent sleep hypoxia which occur in OSAH patients promote oxidative stress and inflammation which in turn lead to insulin resistance, dyslipidemia, abnormal vascular reactivity and other processes which are consistent with the metabolic syndrome.
