Abstract: Background Although exercise rehabilitation has been proven to be safe and effective for cardiovascular patients, adherence is not optimistic. Whether exercise produce sustained benefits was closely associated with adherence, but current studies failed to depict the relationship between exercise adherence and recurrence of atrial fibrillation in patients undergoing radiofrequency ablation procedure.Aim Exploring the influencing factors on recurrence of atrial fibrillation (AF) in patients undergoing radiofrequency ablation procedure. Methods A total of 246 atrial fibrillation patients who underwent radiofrequency ablation surgery in a tertiary hospital in Nanjing from May to November 2020 were selected as the study subjects. Statistical analysis was conducted on the relevant data of 151 patients who participated in all five phases of the investigation, including adherence to exercise rehabilitation (including intensity-time adherence and frequency adherence), Patient activation measure13, Cardiac Rehabilitation Inventory, and general information. The generalized estimating equation was used to explore the influencing factors on post-ablation recurrence in atrial fibrillation patients.Results This study had a total of 23 patients who experienced recurrence. The results from the generalized estimating equation showed that BMI, smoking, type of atrial fibrillation, activation level, process anxiety, outcome anxiety and intensity-time adherence were all factors influencing the recurrence situation. Conclusions The adherence to home-based exercise rehabilitation in patients with atrial fibrillation after radiofrequency ablation changes progressively. It is recommended that healthcare professionals pay attention to guiding and supervising exercise intensity, take targeted measures to reduce process anxiety and outcome anxiety, in order to effectively improve patient prognosis through exercise rehabilitation.
