Andersen-Tawil综合征1型(ATS1)是一种罕见的致心律失常综合征,是由KCNJ2基因发生功能缺失突变导致。本研究旨在确定威胁生命的心律失常事件(LAE)的风险,确定此类事件的预测因素,并确定ATS1患者抗心律失常治疗的疗效。

本研究纳入分析了118名来自23个临床中心的ATS1患者(平均年龄23 ± 17岁),经过平均6.2年时间的随访,有17名患者发生第一次LAE,5年累计发生率为7.9%。LAE发生风险的增高与昏厥病史、持续性室性心动过速(HR 9.34;p=0.001)和胺碘酮(HR:268;p<0.001)的使用相关([HR]: 4.54; p = 0.02)。另外,单独使用β受体阻滞剂(1.37/100py;p=1.00)或联合使用Ic类抗心律失常药物(1.46/100py,p=1.00)均不能降低未经治疗的LAE发生率。

研究结果显示,ATS1患者的临床特征具有较高的LAE发生率。不明原因晕厥史或记录的持续性室性心动过速与LAE的高风险相关。胺碘酮是致心律失常的药物,在ATS1患者中应避免使用。
