Sponsor's own description

Sleep apnea is a prevalent disorder in patients with coronary artery disease. Previous studies suggested sleep apnea was associated with coronary plaque burden and future adverse cardiovascular events after percutaneous coronary intervention. In the SABOT study, the investigators used a FDA-approved portable sleep device to diagnose sleep apnea, and evaluate the relationship between sleep apnea and cardiovascular outcomes after non-urgent coronary artery bypass surgery.
