Abstract:
Objective To observe the value of left atrial strain combined with electrocardiogram(ECG)P-wave parameters for predicting recurrence of paroxysmal atrial fibrillation(PAF)after pulmonary vein isolation(PVI)using radiofrequency catheter.Methods Totally 88 PAF patients who planned to receive the first PVI were prospectively enrolled and divided into recurrence group(n=30)and non-recurrence group(n=58)according to results of ECG within 6 months after PVI.The patients'basic data,the transthoracic echocardiography(TTE)parameters,including left atrial reservoir strain(LASr),left atrial conduct strain(LAScd)and left atrial contraction strain(LASct),as well as ECG parameters including P-wave duration,PR interval and P/PR(the ratio of P-wave duration to PR interval)were compared between groups.Multivariate logistic regression analysis was performed of parameters being statistically different between groups to screen independent predictors for recurrence of PAF after PVI.The receiver operating characteristic curve and the area under the curve(AUC)were used to evaluate the predicting efficacy of individual independent predictors alone and their combination,and DeLong test was used for comparison.Results No significant difference of patients'basic data was found between groups(all P＞0.05).Compared with those in non-recurrence group,LASr and LAScd decreased while P/PR increased in recurrent group(all P＜0.05).LASr(OR=0.805),LAScd(OR=0.850)and P/PR(OR=1.119)were all independent predictors for recurrence of PAF after PVI(all P＜0.05),with AUC of 0.755,0.643 and 0.771,respectively,all lower than their combination(AUC=0.869)(all P＜0.05).Conclusion TTE and ECG parameters could be used to predict recurrence of PAF after PVI.The predicting efficacy of the combination of LASr,LAScd and P/PR was better than that of each alone.
