OBJECTIVE: We aimed to identify the impact of re-exploration for bleeding after coronary artery bypass grafting (CABG) and the effect of time delay, re-exploration within 12h (or=12h). METHODS: Analyses of prospective clinical data on 3220 consecutive patients who underwent CABG between 2003 and 2005 were performed. Pearson chi(2) tests, Fisher s exact tests, Student s t-tests, Mann-Whitney U tests, or univariate logistic regression analysis were used to assess the effects of pre-operative and operative characteristics on re-exploration, and the effects of re-exploration and time delay on adverse outcomes. Predictors of re-exploration and its effect on adverse outcomes were further evaluated using multiple logistic regression analysis. RESULTS: One hundred ninety-one patients (5.9 ) underwent re-exploration for bleeding. Re-explored patients as a group in comparison to the non-re-explored group had increased postoperative blood loss, transfusion requirements, duration of mechanical ventilation, ICU stay, intra-aortic balloon pump (IABP) and haemofiltration support, and mortality (all por=12h group had shorter ICU stay (median 3 vs 8.5 days; por=12h group was significantly higher than the predicted EuroSCORE risks of 7.59 (p
