The Predictive Value of Two-Dimensional Speckle Tracking Echocardiography in Predicting Recurrence in Patients with Paroxysmal Atrial Fibrillation After First Transcatheter Radiofrequency Ablation
Objective:Exploring the clinical significance of two-dimensional spot tracking imaging for the recurrence of arrhythmia in patients with paroxysmal atrial fibrillation after the first radiofrequency ablation surgery. Methods:A total of 70 patients with paroxysmal atrial fibrillation who were admitted to the hospital from July 2022 to August 2023 were selected as the study subjects. All patients underwent transcatheter radiofrequency ablation treatment and were divided into two groups based on the recurrence of atrial fibrillation after treatment,with 35 patients in each group;The study selected 70 healthy individuals from the same period as the control group. Compared the left atrial structure and echocardiography parameters of three groups,and analyzed the predictive value of postoperative recurrence using ROC curve analysis. Results:After surgery,the values of LAAPD,LAUDD,LALRD,LAVmin,LAVmax,and LAVp in the non recurrent atrial fibrillation group were lower than those in the recurrent atrial fibrillation group,while LAEF/%,LAAEF/%,and LAPEF/% were higher than those in the recurrent atrial fibrillation group (P<0.05);Based on the results of Logistic regression analysis,a prediction model was established,and the calculated combined detection probabilities of left atrial structure and echocardiogram parameters were 0.882,0.833,and 0.757 under the ROC curve;The ROC asymptotic 95% confidence intervals for predicting the combined detection of left atrial structure and echocardiographic parameters were 0.794-0.971,0.733-0.934,and 0.645-0.871. Conclusion:The use of two-dimensional spot tracking imaging in the first radiofrequency ablation of paroxysmal atrial fibrillation patients can effectively improve the structure and function of the left atrium,thereby providing high predictive value for disease recurrence.
