Karabacak et al.[17] and Aksoy et al.[18], in their studies to predict new-onset atrialfibrillation after CABG, showed that CAR indicates a higher inflammatory state andis better than CRP and albumin alone at detecting postoperative atrial fibrillation.Furthermore, CAR has been shown to be an independent predictor of saphenous veingraft disease and to have an association with atherosclerosis[19,20]. Here, CRP is linked to atrial fibrillation.
