Postoperative Outcomes in Obstructive Sleep Apnea Patients Undergoing Cardiac Surgery: A Systematic Review and Meta-analysis of Comparative Studies

Obstructive sleep apnea (OSA) is a common comorbidity in patients undergoing cardiac surgery and may predispose patients to postoperative complications. This meta-analysis determines the evidence of postoperative complications associated with OSA patients undergoing cardiac surgery and demonstrates that after cardiac surgery, major adverse cardiac or cerebrovascular events and newly documented postoperative atrial fibrillation had 33.3% and 18.1% higher odds in OSA versus non-OSA patients, respectively.
