Evaluation of the effect of preoperative HbA1c value on development of postoperative atrial fibrillation in diabetic patients with on‐pump coronary artery bypass graft

Background We aimed to determine the relationship between hemoglobin A1c (HbA1c) levels and the development of postoperative atrial fibrillation (PoAF). Methods Two hundred and eighty‐eight patients diagnosed with diabetes mellitus and undergoing on‐pump coronary bypass were included in the study. T...

Description
Summary:	Background We aimed to determine the relationship between hemoglobin A1c (HbA1c) levels and the development of postoperative atrial fibrillation (PoAF). Methods Two hundred and eighty‐eight patients diagnosed with diabetes mellitus and undergoing on‐pump coronary bypass were included in the study. Those with serum HbA1c levels between 5.5% and 7.0% were defined as Group 1, those with serum HbA1c levels between 7.1% and 8.9% were defined as Group 2, while those with serum HbA1c levels 9.0% and above formed Group 3. Data between groups were compared. The predictive values of the independent variables for the development of PoAF were measured. Results We did not find a difference between groups in terms of development PoAF (p = .170). The presence of hypertension was determined as an independent predictor for the development of PoAF (p = .003), but not HbA1c levels (p = .134). There was 50.5% sensitivity and 61.1% specificity for HbA1c values of 9.06% and above to predict PoAF (area under curve: 0.571, p = .049). Conclusions HbA1c levels were not an independent predictor of PoAF development. However, we think that high HbA1c levels may be a risk factor for the development of PoAF.
