摘要 目的:研究肾功能不全与肺静脉前庭隔离术治疗阵发性房颤后长期随访结果的关系。方法:回顾性分析335例阵发性房颤患者临床资料,依据肾小球滤过率(eGFR)水平分为3组,组Ⅰ[正常eGFR,eGFR≥90 mL/(min·1.73 m^2),107例],组Ⅱ[eGFR轻度降低,eGFR 60~90 mL/(min·1.73 m^2),193例]和组Ⅲ[eGFR中重度降低,e GFR≤60 mL/(min·1.73 m^2),35例]。在三维标测系统指导下行肺静脉前庭隔离术达到肺静脉-左房电学隔离,术后常规程序刺激诱发,若合并室上性心律失常或者非肺静脉触发灶,同时消融。结果:患者年龄随着eGFR下降有增高趋势。低eGFR组有更高比例的高血压发生率、增大的左房内径、更长的房颤病程及脑梗死或短暂性脑缺血发作病史。3组间非肺静脉触发灶发生率无明显差别。首次消融术后72例患者复发快速性房性心律失常,组Ⅲ复发率(40%)明显高于组Ⅰ和组Ⅱ。生存曲线提示3组间快速性房性心律失常的复发比例亦有显著差异。多因素Cox分析提示,CHA2DS2-VASc及房颤病程是导管消融术后快速性房性心律失常复发的独立预测因素。结论:低eGFR合并高CHA2DS2-VASc评分及更长病程的阵发性房颤患者,射频消融术后有更高的复发率。
