心房颤动导管消融术后复发的相关因素

The Related Factors of Recurrence of Atrial Fibrillation after Catheter Ablation

心房颤动(简称房颤)治疗方法主要有药物治疗和射频消融术等。药物治疗往往是经验性的,且副作用大,会导致许多心脏及心脏以外的不良反应,长期用药,患者的依从性较差,治疗效果有限。2014年AHA/ACC/HRS心房颤动指南中,对于有症状且药物治疗无效的阵发性心房颤动患者,导管消融术被推荐为治疗房颤的一线方法 (Ⅰ,A)。但导管消融术后存在一定的复发现象。引起房颤导管消融术后复发的因素较多,如左房大小、心率、PR间期、炎症因子等。准确预测房颤导管消融术后复发的相关因素,有助于早期识别高危人群,从而采取相关的预防措施。

Drug and radiofrequency ablation were used to treat atrial fibrillation （AF）. Because the drug therapy is often empirical, and the side effects of drug can leads to many adverse reactions of heart and heart outside. Patient＇s compliance is poor after long term medication, so the therapeutics effect is limited. At present, catheter ablation is the main therapy for the treatment of AF, and 2014 AHA/ACC/HRS guidelines has been recommended for the treatment of AF in the first line. But there is a certain recurrence after ablation. There are many factors that cause the recurrence of AF, such as left atrial size, heart rate, PR interval, inflammatory factors. Accurate prediction of recurrence of AF after catheter ablation is helpful for early identification of high-risk groups, so as to take relevant preventive measures.
