Background and Aims. Radiofrequency ablation is a commonly used treatment for paroxysmal atrial fibrillation (AF), but postoperative rehabilitation exercises are needed to reverse left ventricular structural and functional abnormalities. This meta-analysis aimed to evaluate the intervention effect of exercise training in patients with AF after radiofrequency ablation. Methods. A systematic literature search was conducted to identify articles in PubMed, MEDLINE, EMBASE, and the Cochrane Library from January 1, 2010 to December 1, 2021. The mean difference with 95% CI was pooled for continuous variables. We used Review Manager 5.3 for the standard meta-analysis. This study followed the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Results. Ten randomized controlled trials (RCTs) were included, with a total of 892 patients with AF. The quality of one study was grade A, and the rest were grade B. The results of the meta-analysis showed that the improvement of 6 min walking distance (MD = 34.42, 95% CI: 3.20 to 65.63, P = 0.03), peak oxygen uptake (MD = 1.96, 95% CI: 1.14 to 2.78, P < 0.001), left ventricular ejection fraction (LVEF) (MD = 0.09, 95% CI:0.01–0.17, P = 0.02), resting heart rate (MD = −4.50, 95% CI: −8.85 to −0.14, P = 0.04), and physical component summary (PCS) (MD = 3.00, 95% CI: 0.46 to 5.54, P = 0.02) in the experimental group was significantly better than that of the control group, and the difference was statistically significant. Conclusion. Exercise training can improve the level of exercise endurance and cardiac function in patients. However, the results were limited by the quantity and quality of the studies. Large samples and high-quality studies are still needed to verify its long-term efficacy. [ABSTRACT FROM AUTHOR]

The aim of this study was to grasp the current situation of fear of recurrence in patients after radiofrequency ablation of atrial fibrillation and to explore the application effect of cognitive-behavioral stress management in patients with fear of recurrence after radiofrequency ablation of atrial fibrillation. From July 2020 to July 2021, 150 patients with fear of recurrence of atrial fibrillation after radiofrequency ablation in our hospital were divided into a control group and an intervention group, with 75 cases in each group. Both groups received conventional nursing methods, and the intervention group received 8 weeks of cognitive-behavioral stress management. Before the intervention and after the intervention, the general situation questionnaire, the Chinese version of the Fear Disease Progression Simplified Scale (FoP-Q-SF), the Perceived Stress Scale (CPSS), and the Positive Psychological Capital Questionnaire (PPQ) were used for evaluation. Before the intervention, there were no significant differences in general data, degree of fear of recurrence, stress perception, and psychological capital scores between the two groups (P > 0.05). After 8 weeks of cognitive-behavioral stress management intervention, the fear recurrence, the total score of stress perception, and the scores of each dimension in the intervention group were significantly lower than those in the control group, and the psychological capital score was significantly higher than that in the control group, with statistically significant differences (P < 0.05). Cognitive-behavioral stress management method can significantly reduce the fear of recurrence and stress level of patients after radiofrequency ablation of atrial fibrillation, and improve their psychological capital level.
