Evaluation of the Effect of Preoperative HbA1c Value on Development of
Postoperative Atrial Fibrillation in Diabetic Patients with On-Pump
Coronary Artery Bypass Graft.
Abstract
Background: We aimed to determine the relationship between
HbA1c levels and the development of postoperative atrial fibrillation
(PoAF) . Methods: 288 patients diagnosed with diabet and
undergoing on-pump coronary bypass were included in the study. Those
with serum HbA1c levels between 5.5-7.0% were defined as Group 1, those
with serum HbA1c levels between 7.1-8.9% 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 found difference between groups in terms of development PoAF
(p=0.170). Presence of hypertension was determined as an independent
predictor for the development of PoAF (p=0.003) but not HbA1c levels
(p=0.134). There was 50.5% sensitivity and 61.1% specificity for HbA1c
values of 9.06% and above to predict PoAF (AUC: 0.571, p=0.049)
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.
