JCE:使用抗心律失常药物不影响房颤消融的疗效

2013-06-27 JCE dxy

环肺静脉射频消融术(Pulmonary vein isolation,PVI)是近年出现的房颤治疗新方法,主要用于药物治疗效果不佳或药物不能耐受的房颤患者。PVI治疗房颤的主要机制是电隔离肺静脉,后者被认为是心房触发灶发生的主要部位。在PVI后测定消融线是否达到完全隔离是评价消融成功的标准。多数临床中心建议患者在PVI期间仍服用抗心律失常药物,并维持至术后3个月,然而停药后房颤的复发十分常见,据统

环肺静脉射频消融术(Pulmonary vein isolation,PVI)是近年出现的房颤治疗新方法,主要用于药物治疗效果不佳或药物不能耐受的房颤患者。PVI治疗房颤的主要机制是电隔离肺静脉,后者被认为是心房触发灶发生的主要部位。在PVI后测定消融线是否达到完全隔离是评价消融成功的标准。多数临床中心建议患者在PVI期间仍服用抗心律失常药物,并维持至术后3个月,然而停药后房颤的复发十分常见,据统计复发率高达14%-80%。 目前PVI仅作为房颤消融的二线治疗,主要用于药物治疗效果不佳或不能耐受的患者,因此许多患者在进行PVI前使用过抗心律失常药物,然而目前对于PVI围手术期是否停用抗心律失常药物还存在争论,理论上PVI手术期间使用抗心律失常药物可影响消融效果的评判,但目前还缺乏临床证实,据此Dukes JW等近来在JCE上发表了一篇临床研究。 该研究共入选180例首次进行PVI的房颤患者,所有患者均来自美国约翰-霍普金斯大学医院,根据患者手术期间是否服用抗心律失常药物将患者分成两组:使用抗心律失常药物的患者127例,这些患者的平均随访时间为24.6个月;未使用抗心律失常药物的患者53
