Abstract：Objective To investigate the association between chronic renal insufficiency and recurrence after catheter ablation in patients with atrial fibrillation(AF).Methods We selected 279 non-valvular AF patients who received radio frequency catheter ablation(RFCA).The patients were allocated to the recurrence group and non-recurrence group accord-ing to the AF recurrence or not.Age,sex,body mass index(BMI),TIA or stroke,hypertension,diabetes,renal insuffi-ciency,CHADS2score,CHA2DS2-VASc score,and high-sensitivity C-reactive protein(hs-CRP)were compared between the two groups.Recurrence factors after atrial fibrillation ablation were evaluated by using Cox multivariate analysis.Re-sults After mean follow-up of 12.6 ±3.1 months,107 patients had AF recurrence and 172 patients without recurrence. Patients with chronic renal insufficiency had a higher incidence of AF recurrences(62.7%)as compared with the normal renal function patients(32.9%,P<0.05).There were significant differencs in age, constitution of renal insufficiency, and CHA2DS2-VASc score between the recurrence group and non-recurrence group(all P<0.05).Cox multivariate analy-sis revealed that chronic renal insufficiency was an independent risk factor for AF recurrence(HR=2.561,95%CI:1.455-4.508,P<0.001).Conclusion Chronic renal insufficiency is closely related to AF recurrence after catheter ablation.
