Abstract：Objective To analyze the clinical values of different strategies of radiofrequency ablation (RFA) in treatment of long-term sustained atrial fibrillation (AF).Methods The patients with long-term sustained AF hospitalized in the General Hospital of Chinese People’s Armed Police were chosen and randomly divided into control group [treated with electrical cardiovension after circumferential pulmonary vein ablation (CPVA) and left atrial linear ablation] and observation group (treated with electrical cardiovension immediately after CPVA and then given left atrial linear ablation). The indexes related to the operation, heart function and level of serum high-sensitivity C-reactive protein (hs-CRP) were compared between 2 groups.Results The total duration of the operation, and durations of left atrial linear ablation, ablation discharge and X-ray exposure were significantly less in observation group than those in control group after treatment (P<0.05). The index of left atrial diameter (LAD) was lower and index of left ventricular ejection fraction (LVEF) was higher in observation group than those in control group after treatment (P<0.05). The level of hs-CRP was significantly lower in observation group than that in control group at each stage after treatment (P<0.05). Conclusion The therapy of electrical cardiovension immediately after CPVA and then left atrial linear ablation is more reasonable, and can improve heart function and reduce the level of hs-CRP in patients with long-term sustained AF.
