Determination of the value of glycated hemoglobin HbA and fructosamine in assessing the risk of perioperative complications after cardiac surgery in patients with type 2 diabetes.

Introduction: Patients with diabetes have a worse postoperative course and longer length of hospital stay after surgery. A good indicator of proper long-term (3 months) glycemic control is glycated hemoglobin (HbA), and fructosamine in the short term (2-3 weeks).

Aim: To determine the degree of glycemic control evaluated preoperatively by HbA and/or fructosamine influence on the postoperative course of patients with diabetes undergoing coronary artery bypass grafting (CABG) in 2014-2015.
