The aim of this investigation is to compare the postoperative renal outcomes after on-pump beating- heart versus conventional cardioplegic arrest coronary artery bypass grafting (CABG). Between January 2010 and December 2012, 254 patients who underwent isolated CABG were enrolled. The primary outcome was postoperative acute kidney injury (AKI) within 7 days [defined by the Kidney Disease Improving Global Outcome (KDIGO) Clinical Practice Guideline] and loss of kidney function at 1 year (defined as > 20% loss in estimated glomerular filtration rate from baseline preoperative creatinine level). There was less AKI found for the on-pump beating-heart CABG (30.2% versus 46.3%; p = 0.010) group; with significant less stage I AKI (17.6% versus 29.5%; p = 0.035); a trend of less stage II AKI (4.4% versus 10.5%; p = 0.088) and no significant difference in stage III AKI (8.2% versus 6.3%; p = 0.587). The on-pump beating-heart group also had less patients who have lost their kidney function at 1 year (24.8% versus 41.2%; p = 0.021). Furthermore, multivariate analysis identified conventional arrest CABG is an independent risk factor for postoperative AKI and loss of kidney function at 1 year. On-pump beating-heart CABG has superior short-term and mid-term renal outcomes than conventional cardioplegic arrest CABG.
