title: Risk factors for post coronary artery bypass graft atrial fibrillation: role of obstructive sleep apnea.
abstract: In this chapter, we start by discussing coronary artery bypass grafting and the most common complication after surgery  post coronary artery bypass grafting atrial fibrillation (PCAF). We then discuss the major risk factors for PCAF, and subsequently conduct an in-depth discussion of obstructive sleep apnea as a risk factor. In this endeavor, we outline how obstructive sleep apnea is diagnosed, its pathophysiological relationship to PCAF, and recent clinical studies investigating the association between obstructive sleep apnea and PCAF. We conclude with prevention and treatment strategies for PCAF, and a discussion of future research recommendations.
