About this trial
Hypoglossal nerve stimulation (HGNS) is an implantable therapy that treats obstructive sleep apnea.
The study will evaluate the effect of this treatment on cardiovascular and metabolism-related measures to see if it affects patients' risk of medical problems associated with obstructive sleep apnea (OSA).
