Abstract

Abstract: 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.
