Özet

Aim: We aimed to investigate the relationship between the recurrence of AF and P wave duration index (PWDI) in patients with nonvalvular PAF. Methods: We included 114 patients who underwent cryoballoon catheter ablation with the diagnosis of paroxysmal atrial fibrillation (PAF) (55 male, 59 female; mean age 55.5 +/- 10,9 years). PWDI was calculated by dividing the Pwd by the PR interval in DII lead of 1201ead ECG. Patients had regular follow-up visits with 12-lead ECG, medical history and clinical evaluation. 24 h Holter ECG monitoring had been recorded at least 12 months after ablation. Results: AF recurrence was detected in 24 patients after 1 year. Patients were divided into two groups according to the AF recurrence. All parameters were compared between the two groups. Age, DM, HT frequency, ACEI-ARB use, CHA2DS2VASc and HAS-BLED score, HsCRP, LA diameter, LA volume, LA volume index, Pwd and PWDI were related to AF recurrence. In binary logistic regression analysis, PWDI (OR = 1.143, p = 0.001) and HT (OR = 0.194, p = 0.020) were found to be independent parameters for predicting AF recurrence. Every 0,01 unit increase in PWDI was found to be associated with 14.3% increase in the risk of AF recurrence. The cut-off value of PWDI obtained by ROC curve analysis was 59,9 for prediction of AF recurrence (sensitivity: 75.0%, specificity: 69.0%). The area under the curve (AUC) was 0.760 (p < 0.001). Conclusion: Increased PWDI may help to identify those patients in whom electrical remodeling has already occurred and who will get less benefit from cryoablation. (C) 2017 Elsevier Inc.
