Objective
Despite the improved procedural outcomes with advences in ablation techniques, postablation atrial fibrillation recurrence has continued to be a major clinical problem after pulmonary vein isolation, occuring in 25% to 50% of patients during follow-up. We aimed to determine whether the precense of a pre and postablative inflammatory state, determined using known clinical parameters and conventional markers of inflammation, including high-sensitivity C-reactive protein (CRP),neutrophil lymphocyte ratio (NLR) and RDW, could be associated with atrial fibrillation recurrence after cryoablation.
Methods
İn the present prospective and observational study, we enrolled 48 consecutive patients who had undergone pulmonary vein isolation with the cryoballoon technique for documented atrial fibrillation from september 2012 to january 2014. Follow-up examinations were performed 1, 3 and 6 months after the procedure and every 6 months thereafter. Late recurrence was defined as the detection of atrial fibrillation (at least 30-second duration assessed with the electrocardiographic monitoring) >3 months after the atrial fibrillation ablation.
