Comparison of inflammatory markers for the prediction of atrial fibrillation recurrence following cryoablation

Aim: The aim of this study is to investigate the value of inflammatory markers for atrial fibrillation (AF) recurrence prediction after cryo-balloon ablation (CA).Materials & methods: The study included 399 patients divided into two groups by AF recurrence after CA. Inflammatory markers including uric acid/albumin ratio (UAR), systemic immune inflammation index (SIII) and CRP/albumin ratio (CAR) were evaluated.Results: UAR, SIII, and CAR were independently associated with the risk of recurrence in AF patients following CA. In ROC curve analysis, CAR had a greater area under curve (AUC:0.73) value than either SIII (AUC:0.68) or UAR (AUC:0.64).Conclusion: Our study results indicate that CAR compared with SIII and UAR had a greater predictive value than others inflammatory markers in predicting AF recurrence post-CA.
