房颤导管消融术复发的危险因素

导管消融技术改变了心房颤动的治疗策略，且其疗效确切，手术创伤小。导管消融术治疗房颤结局显著优于抗心律失常及控制心室率等药物的治疗方案，但其术后心房颤动的复发率高，其复发的影响因素包括年龄、性别、体重指数、基础疾病、左心房体积、肺静脉容积、基因、房颤类型、手术方式等。针对这些因素进行相应调整，对改善导管消融术后的临床疗效及预后至关重要。

Risk factors for atrial fibrillation recurrence after catheter ablation

Th e advent of catheter ablation technology has changed the treatment strategy for atrial fi brillation,and the efficacy of catheter ablation is accurate with small surgical trauma. Catheter ablationtreatment of atrial fi brillation is signifi cantly bett er than pharmacologic therapy of anti-arrhythmiaand rate control. However, the clinic data of catheter ablation of atrial fibrillation show that therecurrence rate is high. The risk factors for recurrence after catheter ablation include age, sex,body mass index, related primary disease, left atrial volume, pulmonary vein volume, gene, atrialfibrillation types, surgery and so on. Regulation of the above factors is crucial in improving theclinical effi cacy and prognosis of catheter ablation of atrial fi brillation.
