Background. Glycemic control in the perioperative period decreases mortality and morbidity, but data are scarce with regard to the effects of glucose control approaches on survival. We assessed long-term survival in patients treated with 2 strategies of glucose control after first-time isolated coronary artery bypass graft. Methods. In a previously published trial, patients were prospectively randomized to strict (90-120 mg/dL) or liberal (121-180 mg/dL) glucose control protocols. The aim of this study was to assess long-term data on survival and health-related quality of life based on the original prospective randomized study population. Results. No differences were found in cumulative survival between the strict (95.5%) and liberal (93.5%) target range groups (log-rank = 0.32, p = 0.57) over a mean follow-up of 40.0 +/- 4.4 months. Physical health-related quality of life significantly improved in all patients from baseline to 6 months after surgery (F = 17.73, p < 0.001), and there were no differences in improvement of health-related quality of life between the 2 target range groups (F = 0.15, p = 0.70). Conclusions. These results support our previous findings and indicate that a liberal glycemic control strategy after coronary artery bypass leads to survival rates and improvements in health-related quality of life that are similar to those achieved with a strict target range. In addition, the liberal strategy is superior in glucose control and target range management. (C) 2014 by The Society of Thoracic Surgeons
