Postoperative atrial fibrillation (PoAF) is the most frequently encountered rhythm problem after coronary artery bypass graft (CABG) operations. This situation decreases the capacity of the patients for functional exercise and creates a risk of stroke. In this study, we aimed to determine the effect of coronary artery disease extensiveness and HATCH score on PoAF in patients undergoing CABG surgery with cardiopulmonary bypass.
Patients who underwent CABG between December 2014 and December 2018 were included in the study retrospectively. Preoperative demographic characteristics, laboratory parameters, and operative parameters of the patients were recorded retrospectively.
Of the 352 patients, 274 had HATCH scores ≤2 (71.1% male, mean age: 61.7 ± 12.4 years) and 78 had HATCH scores >2 (69.2% male, mean age: 65.9 ± 11.7 years). Significant differences were found between the two groups in terms of the age (p= 0.014), presence of hypertension (p=0.012), PoAF (p<0.001) and the SYNTAX score I (p=0.001). Having a HATCH score of > 2 and SYNTAX score I were identified as independent predictors of PoAF (OR: 1.022, 95% CI: 1.004-1.128, p=0.032 and OR: 1.098, 95% CI: 1.035-1.164, p=0.002, respectively). For predicting PoAF, the cut-off level in the ROC curve analysis was 19.7 for SYNTAX score (AUC: 0.647, 95% CI: 0.581-0.714, p<0.001, 72.2 % sensitivity and 66.4% specificity), the cut-off level for HATCH score was 2 (AUC: 0.656, 95% CI: 0.595-0.722, p<0.001, 69.4% sensitivity and 56.8% specificity) Conclusions: As conclusion, we could predict PoAF risk with the HATCH and SYNTAX scores.
