Objective To explore the relationship between body mass index(BMI)and recurrence of catheter ablation in elderly patients with atrial fibrillation and its predictive value for recurrence of atrial fibrillation.Methods Using a retrospective analysis,219 elderly(≥60 years old)patients with atrial fibrillation who underwent catheter abla-tion at the Department of Cardiovascular,The First Affiliated Hospital of Anhui Medical University from January 2018 to December 2019 was collected as the study subjects.And general information,physical measurements,hematology,and cardiac ultrasound imaging were collected,and analyze the effect of BMI and recurrence of catheter ablation in elderly patients with atrial fibrillation,and the predictive value on the recurrence of postoperative atrial fibrillation.Results High BMI,type of atrial fibrillation with non-paroxysmal and high LAD were independent influence factors for recurrence after catheter ablation of atrial fibrillation.And BMI had a good predictive value for recurrence of catheter ablation in pa-tients with atrial fibrillation(AUC=0.595,95％CI:0.526-0.662,P=0.016).Conclusions High BMI is an inde-pendent factor influencing the recurrence of catheter ablation in elderly patients with atrial fibrillation,and it has some predictive value for the recurrence of catheter ablation in elderly patients with atrial fibrillation.
