INTRODUCTION: Although it has been recognised as a @entity65 factor, data on @entity25 screening before coronary artery bypass grafting (CABG) are scarce. This study sought to determine the prevalence, predictors and effects of @entity25 on re-admission in @entity1 undergoing CABG. METHOD: We prospectively recruited 152 @entity1 to undergo an overnight sleep study before CABG. Sleep apnoea was defined as an apnoea-hypopnoea index of >= 15 events per hour. Data on unscheduled re-admission due to cardiovascular events were collected. RESULTS: Among the 138 @entity1 who completed the sleep study, @entity25 was diagnosed in 69 (50%). The @entity1 who had @entity25 had a lower left ventricular ejection fraction (p  =  0.029), a larger left atrial diameter (p  =  0.014) and a larger left ventricular end-systolic dimension (p  =  0.019) than those who did not. Angiographic SYNTAX and Gensini scores were similar in @entity1 with and without @entity25 . The generalised structural equation model revealed that @entity101 , a high body mass index and @entity177 were independent predictors of @entity25 (p  <  0.05). After an average follow-up of 6      3 months, 12 @entity1 with @entity25 (17.3%) and three @entity1 without @entity25 (4.3%) were involved in unscheduled re-admission. @entity1 with @entity25 were almost five times more likely to have an unscheduled re-admission due to cardiovascular events (adjusted odds ratio: 4.63, 95% CI: 1.24-17.31, p  =  0.023) than those without @entity25 . CONCLUSIONS: Sleep apnoea was prevalent and predictive of unscheduled re-admissions in @entity1 scheduled for CABG.
