Material and Methods
The Institutional Research Review Board approved this study and waived the need for patient consent.
Results
Between January 2003 and December 2007, 5352 patients underwent isolated CABG. Mortality data of 5320 patients (99.4%) were collected until March 31, 2008. After excluding patients with a history of AF or without sinus rhythm preoperatively, data of 5098 patients were used for the analysis. Postoperative AF was documented in 1122 patients (22.0%). Median length of hospital stay was 5 days (IQR, 3 to 6 days) in non-POAF patients and 6 days (IQR, 4 to 7 days) in POAF patients. Median follow-up
Comment
This study shows that the incidence of newly developed POAF after CABG in our population is 22%. This incidence is consistent with other studies [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]. POAF was an independent predictor for late but not for early mortality.
