Sitagliptin for Hyperglycemia in Patients With T2DM Undergoing Cardiac Surgery

The purpose of this study is to determine whether treatment with sitagliptin reduces the
frequency and severity of high blood sugar (hyperglycemia) and the need for continuous
intravenous insulin infusion (CII) in the intensive care unit (ICU) in patients with type 2
diabetes (T2D) undergoing coronary artery bypass graft (CABG) surgery. In addition, the study
seeks to determine whether treatment with sitagliptin is effective in maintaining glycemic
control and in preventing the need for subcutaneous (SC) insulin therapy in patients with T2D
during the transition from intensive care unit (ICU) to regular floor in cardiac surgery
patients with T2D.
