NCT03062748

Brief Summary

The purpose of the study is to compare the relative contribution of systemic inflammation vs. Obstructive Sleep Apnea (OSA) severity (as measured by Apnea Hypopnea Index) in predicting cardiovascular and metabolic aberrations associated with mild-to-moderate obstructive sleep apnea.

Primary Outcomes (3)

  • Presence of the metabolic syndrome

    At least 3 of the following 5 risk factors must be met in order to have the metabolic syndrome: 1. Elevated waist measurement (≥102 cm for men or ≥89 cm for women) 2. Elevated triglycerides (≥150 mg/dL or use of medication) 3. Low HDL cholesterol (\<50 mg/dL for women or \<40 mg/dL for men or use of medication) 4. Elevated blood pressure (≥130 mmHg systolic or ≥ 85 mmHg diastolic or use of medication) 5. Elevated fasting blood sugar (≥100 mg/dL or use of medication) Source: https://www.nhlbi.nih.gov/health/health-topics/topics/ms
