Introduction
In this study, we aimed to investigate the relationship between postoperative
mortality, morbidity, hospital stay and development of postoperative
complications with the glycosylated hemoglobin (HbA1c) level and low left
ventricular ejection fraction (LVEF) in diabetic and non-diabetic patients
who underwent elective coronary artery bypass (CABG) surgery.
Methods
The medical records of patients who underwent CABG at our clinic between
January 2015 and December 2019 were retrospectively analyzed. All patients
were divided into two groups according to their diabetes mellitus (DM)
diagnosis. Diabetic patients were also divided into two groups according to
their HbA1c levels. The HbA1c threshold value was 7%. All patients were
divided into two groups in terms of LVEF. The LVEF threshold value was
40%.
Results
We analyzed 393 patients, of which 304 (77.4%) were male and 177 (45.04%)
patients were diabetic. For lower LVEF and HbA1c values, we found no
relationship between postoperative mortality, prolonged intensive care unit
(ICU) stay and development of postoperative complications. Deep surgical
site infection (DSSI) was found to be more common in diabetic patients who
had a higher HbA1c value. Length of hospital stay was longer in diabetic
patients with HbA1c levels <7%.
Conclusion
No statistically significant relationship was found between LVEF and HbA1c
levels and postoperative mortality, prolonged ICU stay and postoperative
complications.
