title: Determination of the value of glycated hemoglobin HbA1cand fructosamine in assessing the risk of perioperative complications after cardiac surgery in patients with type 2 diabetes.
abstract: BACKGROUND
  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 (HbA1c), and fructosamine in the short term (2-3 weeks).
  
  
  OBJECTIVE
  To determine the degree of glycemic control evaluated preoperatively by HbA1cand/or fructosamine influence on the postoperative course of patients with diabetes undergoing coronary artery bypass grafting (CABG) in 2014-2015.
  
  
  METHODS
  Before the operation HbA1c(N < 7.0) and fructosamine (N < 280 µmol/l) were measured and depending on the results the respondents were divided into 4 groups: group I (n= 46) - normal both parameters; group II (n= 22) - high both values; group III (n= 4) - normal fructosamine/HbA1chigh; group IV (n= 33) - high HbA1c/fructosamine normal. Statistical analysis was performed using thet-test assumingp< 0.05 to be statistically significant.
  
  
  RESULTS
  One hundred and five patients were treated by CABG/OPCAB (39 female, 66 males). The mean age was 65.7 ±7.3, HbA1c: 7.23 ±1.2%, fructosamine: 261.8 ±43.8. There was no difference in the incidence of other postoperative complications between the two groups.
  
  
  CONCLUSIONS
  Glycated hemoglobin and fructosamine levels to a similar extent define the risk of perioperative complications in patients undergoing cardiac surgery. In patients in whom there is a need to quickly compensate for elevated blood glucose consider enabling determination of fructosamine.
