Background The importance of optimal postoperative glycemic control in cardiac patients remains unclear. Various glycemic targets have been prescribed to reduce wound infection and overall mortality rates. Aim of the work: To assess glucose control, as determined by time in range (TIR), in patients with glycemic targets of 6.0 to 8.1?mmol/L, and to determine factors related to poor control. Methods This prospective descriptive study evaluated 227 consecutive patients, 100 with and 127 without diabetes, after cardiac surgery. Patients received insulin to target glucose concentrations of 6.0 to 8.1?mmol/L. Data analyzed included patient age, gender, race, Euro score, cardiopulmonary bypass time (CPB), aortic cross clamp time (ACC), length of ventilation, stay in the intensive care unit (ICU) and stay in the hospital. Patients were divided into two groups, those who maintained--0% and--0% TIR. Outcome variables were compared in diabetics and non-diabetics. Results Patients with >80% and HbA1c)--% (p--.0001), and in patients taking dopamine (p--.04) and adrenaline (p--.05). Times of CPB and ACC, length of stay in the ICU and ventilation were significantly higher in patients with TIR 80%. Rates of hypoglycemia, acute kidney injury, and in-hospital mortality were similar in the two groups, although the incidence of wound infection was higher in patients with TIR Conclusion Patients with >80% TIR, whether or not diabetics, had better outcomes than those with
