BACKGROUND: This study evaluated the impact of decreasing renal function on short-term outcomes in patients undergoing primary coronary artery bypass grafting (CABG).

METHODS: The study period was from February 1999 to February 2009. Data on 4050 patients undergoing primary CABG were prospectively collected and analyzed retrospectively. The study population was divided into 3 groups: the CABG:N group, patients with preoperative serum creatinine levels <2 mg/dL (n = 3947); the CABG:RF group, patients with preoperative creatinine levels >2 mg/dL (n = 87); and the CABG:D group, patients on dialysis (n = 16).

RESULTS: The significant differences between the groups (CABG:D > CABG:RF > CABG:N) in short-term outcomes were with respect to blood product use (P < .001), postoperative acute myocardial infarction (P < .001), pulmonary complications (P .001), infection (P < .001), and death (P < .001). The risk of short-term death (30 days) in the CABG:D group (4/16, 25%) was 25 times greater than that in the CABG:N group (38/3947, 0.96%).

CONCLUSION: CABG in the presence of renal failure is associated with significant morbidity and mortality.
