Visceral Adiposity Index and Prognostic Nutritional Index in Predicting Atrial Fibrillation after On-Pump Coronary Artery Bypass Operations: a Prospective Study

Abstract 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.
