心房颤动患者单次射频消融术后的远期效果及影响因素的观察

Risk factors of long-term recurrence after catheter ablation in patients with atrial fibrillation

目的观察心房颤动(简称房颤)患者射频消融术后的疗效,探索房颤射频消融术后复发的危险因素。方法选取2010年8月至2013年9月首次行房颤射频消融治疗的63例患者,收集临床资料,分析术后长期有效性、探讨影响远期复发的因素。结果 63例房颤患者中,单次消融后第一年随访时23.8%的房颤患者复发,其中阵发性房颤20.8%复发,持续性房颤40%复发。平均随访46.7个月时40.7%的房颤患者复发,其中阵发性房颤38%复发,持续性房颤55.6%复发。年龄为房颤单次射频消融术后复发的独立危险因素(OR=3.8,95%CI:1.264~11.426,P=0.017)。结论射频消融治疗房颤远期观察具有较高的复发率,且年龄大的患者存在更高的复发率。

Objective To evaluate the risk factors of long-term recurrence after catheter ablation in patients with atrial fibrillation（AF）. Methods Clinical data of 63 selected patients,with AF who underwent catheter ablation from August 2010 to September 2013 was collected and the long-term efficacy and risk factors of long-term recur rence were analyzed. Results The recurrence rate of single catheter ablation for AF at first year was 23.8%, the rate of paroxysmal AF was 20.8%, and the rate of persistent AF was 40%. The recurrence rate at average 46.7 months was 40.7%, the rate of paroxysmal AF was 38%, and the rate of persistent AF was 55.6%. After multiva riate regression analysis,the age was an independent risk factor for recurrence after single catheter ablation（OR=3. 8,95%CI ：1.264 11.426,P=0.017）. Conclusions Catheter ablation for AF has a high recurrence rate for longterm follow-up and the recurrence rate is higher in elderly patients.
