Identifying high-risk patients remains a major challenge in coronary surgery. Sleep disordered breathing (SDB) is one of the most common chronic diseases (prevalence 50%) in patients with coronary artery disease. A growing body of evidence indicates that SDB increases the risk of major post-operative complications after abdominal and orthopedic surgery. A few studies have described an association between SDB and new-onset atrial fibrillation after coronary artery bypass graft surgery (CABG), but the impact of SDB on major cardiac, respiratory, cerebral, surgical and infectious post-operative complications following coronary surgery is still unclear Here, we prospectively examined post-operative recovery in patients with stable coronary artery disease who underwent elective CABG. Our aims were 1) to evaluate whether SDB enhances postoperative morbidity, mortality and resource use; and 2) to identify specific SDB-related post-operative complications.
