ABSTRACT
This study aimed to evaluate the impact of the echocardiographic parameter ratio E/E' on the late recurrence of paroxysmal atrial fibrillation in patients after receiving radiofrequency catheter ablation.We retrospectively examined total of 288 paroxysmal atrial fibrillation (PAF) patients that underwent a preliminary radiofrequency catheter ablation (RFCA) in our hospital. During the first phase in this study, the patients were divided into 2 groups upon AF recurrence after RFCA Recurrent group, nâ=â67 patients with rapid trial arrhythmia that lasted for more than 30âseconds at 3 months after RFCA and the Nonrecurrent group, nâ=â221. The clinical conditions were compared between the 2 groups. During the second phase of this study, based on the results in the first phase, the patients were divided into another 2 groups according to whether the ratio of E/E' ≥13 .45 Higher ratio of E/E' group, nâ=â55 and Lower ratio of E/E' group nâ=â233. The late AF recurrent rates were also compared between the 2 groups.During the first phase, the univariate analysis indicated that the risk factors(Pâ<â.05)for PAF late recurrence included early recurrence, E', and the ratio E/E'. The Cox multivariate analysis showed that the ratio of E/E' and early recurrence were the independent predictors for late PAF recurrence. The ratio of E/E' that was cut off at 13.45 also predicted atrial tachyarrhythmia recurrence with 40.3% sensitivity and 87.3% specificity. In the second phase, after completing the 11 matching, the Kaplan-Meier analysis indicated that the ratio of E/E' ≥ 13.45 was associated with further recurrences after RFCA (log-rank Pâ=â.009), compared to the patients with a ratio of E/E' < 13.45. The univariate Cox analysis indicated that an elevated ratio of E/E'(≥13.45) was the independent predictor for late PAF recurrence (HRâ=â3.322, 95%CI 1.560-7.075, Pâ=â.002). However, the ratio of E/E' cut off at 13.25 predicted atrial tachyarrhythmia recurrence with 75% sensitivity and 62.2% specificity.The ratio of E/E' ≥ 13.25 is an important predictor of the late recurrence of paroxysmal atrial fibrillation (PAF) after radiofrequency catheter ablation (RFCA).
