Introduction Rhythm problems are the most observed complications following coronary artery bypass grafting (CABG), the most common being postoperative atrial fibrillation (PoAF), with an incidence reaching 50% of the patients. In this study, we aimed to investigate the predictive importance of prognostic nutritional index (PNI) and visceral adiposity index (VAI) in predicting PoAF, which occurs after CABG accompanied by cardiopulmonary bypass. Methods Patients who underwent isolated CABG with cardiopulmonary bypass between June 15 and October 15, 2019, were prospectively included in the study. Patients who did not develop in-hospital PoAF were identified as Group 1, and those who did constituted Group 2. Results PoAF developed in 55 (27.6%) patients (Group 2). The mean age of the 144 patients included in Group 1 and 55 patients in Group 2 were 56.9±8.7 and 64.3±10.2 years, respectively ( P <0.001). In multivariate analysis Model 1, age (odds ratio [OR]: 1.084, confidence interval [CI]: 1.010-1.176, P =0.009), chronic obstructive pulmonary disease (OR: 0.798, CI: 0.664-0.928, P =0.048), and PNI (OR: 1.052, CI: 1.015-1.379, P =0.011) were determined as independent predictors for PoAF. In Model 2, age (OR: 1.078, CI: 1.008-1.194, P =0.012), lymphocyte counts (OR: 0.412, CI: 0.374-0.778, P =0.032), and VAI (OR: 1.516, CI: 1.314-2.154, P <0.001) were determined as independent predictors for PoAF. Conclusion In this study, we determined that low PNI, a simply calculable and cheap parameter, along with high VAI were risk factors for PoAF.

Backround: Postoperative atrial fibrillation (PoAF), the most common arrythmia observed in 18-40% of patients following coronary artery bypass surgery, may cause hemodynamic disturbances and increase embolism risk. The aim of this study was to investigate the relationship of HATCH score with PoAF in patients who underwent off-pump coronary artery bypass grafting (OPCABG) and evaluate the effect of preoperatively calculated neutrophil-to-lymphocyte ratio (NLR) on PoAF. Methods: Patients who underwent OPCABG between January 2014 and January 2019 were included in the study. Preoperative and postoperative data retrospectively were obtained. Patients who did not develop PoAF during the postoperative hospitalization period constituted Group 1; those who did were classified as Group 2. Results: Ninety-seven patients (69 males and 28 females) with a mean age of 54.4 ± 11.1 years constituted Group 1, and 26 patients (17 males and 9 females) with a mean age of 61±12.6 years constituted Group 2. Significant differences were observed between the 2 groups, in terms of age and HATCH scores (P = .025 and P < .001, respectively). NLR, number of distal anastomoses, intensive care unit (ICU) stay times, and total hospitalization times were significantly higher in Group 2 (P = .021, P = .021, P < .001, P < .001, respectively). HATCH score was identified as an independent predictor of AF development following OPCABG surgery (OR: 2.125, 95 % CI: 1.296–3.482, P = .003). Conclusion: In light of our study, HATCH scores of all patients preoperatively may be calculated so that preventive precautions are taken for high-risk patients.

Objective: Postoperative atrial fibrillation (PoAF) is the most frequently encountered rhythm problem after coronary artery bypass graft (CABG) surgery. This situation decreases the capacity of the patients with respect to functional exercise and creates a risk for 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. Subjects and Methods: Patients who underwent CABG between December 2014 and December 2018 were included retrospectively. Preoperative demographic characteristics, laboratory parameters, and operative parameters of the patients were recorded retrospectively. Results: 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 2 groups in terms of the age (p = 0.014), presence of hypertension (p = 0.012), PoAF (p < 0.001), and SYNTAX (synergy between percutaneous coronary intervention with taxus and cardiac surgery) score I (p = 0.001). A HATCH score >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 cutoff 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), and the cutoff 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: HATCH and SYNTAX scores are predictors of PoAF.
