Comparison Among Clinical Predictors for Atrial Fibrillation Recurrence after Ablation in Patients Without Structural Heart Dis.pdf

1、Objective : Recurrence of atrial fibrillation (AF) is commonly observed after AF catheter ablation. We evaluated and compare the potential of clinical non-invasive approach to predict AF recurrence after ablation in indi

2、vidual without structural heart diseases. Methods and results : We studied 90 Patients (57 Male; 33 female) , age mean 60,39 ± 10,59, with AF, without structural heart disease, who had ablation procedure from June 2010 t

3、o March 2013 and had recurrence within 3 months after procedure. We collect all patient’s data from medical record and direct interview. From 90 patients observed, recurrence occurred in 26 patients (28,9％). P wave durat

4、ion mean on recurrence vs non recurrence patients 121,2 ± 16,3 ms vs 103,8 ± 26,5 ms ; p< 0,05. P wave dispersion mean 49,6 ± 8,2 vs 36,4 ± 5,0 ; p <0,05. Patients with P wave terminal force (PWTF)≥ 40ms (P<0,001) and in

5、terval between notch in lead II≥ 40ms (P<0,001) also have higher recurrence rate after ablation. Left atrial diameter (LAD) mean 37,3 ±2,3 vs 33,1 ±3,5 ; p < 0,05, HsCRP mean 4,9±6,8 vs 2,1±4,6 ; p<0,05. Conclusion : lon

6、ger P wave duration (≥ 125ms), bigger P wave dispersion( > 40 ms), Interval between notch in lead II≥ 40 ms, PWTF≥ 40 ms are good independent predictors for AF recurrence post ablation and so does larger LAD. HsCRP also
