Background Radiofrequency catheter ablation （RFCA） for atrial fibrillation （AF） has developed rapidly,and is a commonly performed ablation in many major hospitals throughout the world,due to its satisfactory *** aim of this study was to detect the effect of RFCA on C-reactive protein （CRP）,brain natriuretic peptide （BNP）,and echocardiograph in patients with persistent and permanent *** A total of 120 patients （71 males,mean age （50.8＆#177;12.0） years） with persistent and permanent AF undergoing RFCA under guidance of the Carto merge technique were *** atrial diameter （LAD）,right atrial diameter （RAD）,left ventricular ejection fraction （LVEF）,CRP,and BNP were observed 3,6 and 12 months after RFCA and compared with results before *** recurrence of atrial arrhythmias was observed 3 and 12 months after the *** Compared with that before RFCA,LAD and RAD decreased and LVEF increased significantly after ***,the levels of CRP and BNP were reduced significantly at 3,6,and 12 months after RFCA （P〈0.05）.In the non-recurrent patients,LVEF was increased significantly compared with the recurrent patients at 3,6,and 12 months after RFCA （P〈0.05）.CRP and BNP levels were decreased significantly in the non-recurrent patients compared with the recurrent patients at 3,6,and 12 months after RFCA （P〈0.05）.After one or two applications of RFCA,during a follow-up of 12 months,12 patients （10.0%） had AF,10 patients （8.3%） had atrial flutter,and 5 patients had atrial tachycardia （4.2%）.Conclusions Conversion of AF to sinus rhythm by RFCA,has been shown to reduce LA size and improve *** can also significantly decrease the levels of CRP and BNP in patients with persistent and permanent AF and reduce the risk of inflammation and developing heart failure.
