Abstract：Objective To investigate the impact of chronic obstructive pulmonary disease(COPD)on the occurrence of thrombotic events and recurrence after radiofrequency ablation in patients with atrial fibrillation.Methods Totally 80 atrial fibrillation patients with COPD(COPD group)and 80 atrial fibrillation patients without COPD(control group)admitted to Qinghai Red Cross Hospital from January 2020 to January 2024 were selected.The occurrence of thrombotic events and the score of atrial fibrillation thrombosis risk-VASc(CHA2DS2-VASc)in the two groups were recorded.All patients underwent radiofrequency ablation.The patients were divided into recurrence group and non-recurrence group according to the recurrence of atrial fibrillation after radiofrequency ablation.The factors affecting the recurrence of atrial fibrillation after radiofrequency ablation were analyzed.Results The total incidence of thrombotic events,the proportion of CHA2DS2-VASc score ≥2,and the postoper-ative recurrence rate in the COPD group were higher than those in the control group[20.0％(16/80)vs 8.8％(7/80),22.5％(18/80)vs 10.0％(8/80),53.8％(43/80)vs 26.2％(21/80)](all P＜0.05).A total of 64 patients had recurrence and 96 patients had no recurrence.The body mass index,the proportion of type 2 diabetes mellitus and COPD in the recurrence group were higher than those in the non-recurrence group.The duration of atrial fibrillation and the left atrial anteroposterior diameter were longer than those in the non-recurrence group,and the left ventricular ejection fraction was lower in the recurrence group than that in the non-recurrence group(all P＜0.05).A longer course of atrial fibrillation and COPD were the risk factors for recurrence of atrial fibrilla-tion after radiofrequency ablation(odds ratio=3.762,2.656,both P＜0.001).Conclusions The incidence of thrombotic events and the recurrence rate after radiofrequency ablation of atrial fibrillation in patients with COPD are higher.COPD is a risk factor for the recurrence of atrial fibrillation after radiofrequency ablation.
