Background and aim: We sought to evaluate the long-term impact of post-cardiac surgery atrial fibrillation on the risk of stroke and survival. Methods: Patients undergoing isolated CABG surgery from April 1, 1995 to March 31, 2007 were identified (n = 8058). Long-term stroke data were compiled using Cox modeling adjusted for clinical characteristics comparing patients with new-onset atrial fibrillation (NwAfib) and those without. Results: NwAfib developed in 2214 patients (27.5%). Overall in-hospital mortality was 2.4% and was not different between groups. Unadjusted in-hospital outcomes suggest patients with NwAfib were more likely to suffer a permanent stroke (1% vs 2.5%; p
