OBJECTIVE: To test the hypothesis that @entity27 ( @entity27 ) is a risk factor for development of @entity955 ( @entity955 ) after cardiac surgery. DESIGN: Retrospective analysis. SETTING: Single-center university hospital @entity1 : Five hundred forty-five @entity1 in sinus rhythm preoperatively undergoing coronary artery bypass grafting (CABG), aortic valve replacement, mitral valve replacement/repair, or combined valve/CABG surgery from January 2008 to April 2011. INTERVENTIONS: Retrospective review of medical records. MEASUREMENTS AND MAIN RESULTS: Postoperative @entity955 was defined as @entity955 requiring therapeutic intervention. Of 545 cardiac surgical @entity1 , 226 (41%) @entity1 developed @entity955 . The risk was higher in 72 @entity27 @entity1 than 473 @entity1 without @entity27 (67% v 38%, adjusted hazard ratio 1.83 [95% CI: 1.30-2.58], p<0.001). Of the 32 @entity27 @entity1 who used home positive airway pressure (PAP) therapy, 18 (56%) developed @entity955 compared with 29 of 38 (76%) @entity1 who did not use PAP at home (unadjusted hazard ratio 0.63 [95% CI: 0.35-1.15], p = 0.13). CONCLUSION: @entity27 is significantly associated with @entity955 in cardiac surgery @entity1 . Further investigation is needed to determine whether or not use of positive airway pressure in @entity27 @entity1 reduces the risk of @entity955 .
