Among patients undergoing coronary artery bypass graft (CABG) surgery, little is known about how often glucose control is achieved in community practice and what predicts better or worse glucose control.
We studied 2,305 patients undergoing CABG or CABG+valve surgery at 55 U.S. hospitals participating in the Contemporary Analysis of Perioperative Cardiovascular Surgical Care (CAPS–Care) registry. In–range glucose control was defined as glucose levels between 70 and 180 mg/dL during the first 24 hours after surgery.
Overall, 701/2,305 patients (30.4%) had their glucose managed in–range during the initial 24–hour postoperative period. Of those not controlled, 87.0% had hyperglycemia only, 5.1% had hypoglycemia only, and 7.9% had both hyper– and hypoglycemia. Factors associated with better glucose control are shown in the table. Patients with in–range glucose control had significantly lower composite rates of mortality and major complications (reoperations, mediastinitis, stroke, renal insufficiency, or prolonged mechanical ventilation) (adjusted OR 0.70, 95% CI 0.56-0.87, P = 0.002).
Less than one–third of CABG patients in community practice achieved in–range postoperative glucose control during the first 24 hours after surgery. Considerable opportunity exists to improve glucose control in patients undergoing CABG surgery, potentially improving clinical outcomes.
