Key result
Elevated preoperative HbA1c fails to predict PoAF.
Why the study?
The association between preoperative HbA1c levels and the occurrence of postoperative atrial fibrillation in diabetic patients undergoing isolated coronary artery bypass graft surgery was unclear.
Preoperative HbA1c lacks predictive value for PoAF after CABG in diabetics; leaves open role of glycemic control in arrhythmia risk.
The authors performed a detailed retrospective analysis of diabetic patients undergoing isolated coronary artery bypass graft surgery aiming to investigate the association of the preoperative glycosylated hemoglobin with occurrence of postoperative atrial fibrillation. Although statistical analysis showed a weak relationship between HbA1c values of 9.06% or above and postoperative atrial fibrillation (PoAF), they concluded that serum level of HbA1c could not be used as a predictor for the development of PoAF. But there are many questions to be asked and answers to be found.

Ali Baran Budak (2022) conducted a letter in diabetic patients undergoing isolated coronary artery bypass graft surgery. elevated preoperative HbA1c levels (≥9.06%) was evaluated on postoperative atrial fibrillation (PoAF). Preoperative HbA1c levels of 9.06% or above showed a weak relationship with postoperative atrial fibrillation and could not be used as a predictor for its development.
