JACC:长QT综合征的风险分层评估体系的建立

2018-04-16 MedSci MedSci原创

长QT综合征(LQTS)是一种常见的遗传性心律失常,常由KCNQ1、KCNH2和SCN5A基因突变导致,该疾病会引起致死性心律失常事件(LAEs)的发生。本研究的目的旨在建立一个风险分级的评估体系,以量化LQTS患者的心律失常发生的风险。本研究纳入了数据库中1710名LQTS患者,平均随访时间是7.1年,对其5年LAEs的发生率进行评估,并评价β受体阻滞剂的抗心律失常效果。分析结果显示,无论LQT

长QT综合征(LQTS)是一种常见的遗传性心律失常,常由KCNQ1、KCNH2和SCN5A基因突变导致,该疾病会引起致死性心律失常事件(LAEs)的发生。本研究的目的旨在建立一个风险分级的评估体系,以量化LQTS患者的心律失常发生的风险。

本研究纳入了数据库中1710名LQTS患者,平均随访时间是7.1年,对其5年LAEs的发生率进行评估,并评价β受体阻滞剂的抗心律失常效果。分析结果显示,无论LQTS的类型,QT间期每增加10ms,患者发生LAEs的风险增加15%,在不同的LQTS类型中,与LQT1相比,LQT2和LQT3患者的LAEs发生率要分别高出130%和157%。此外,在接受β受体阻滞剂治疗的患者中,只有纳多洛尔会减少心律失常的发生率(HR:0.38; 95% Cl: 0.15-0.93; p = 0.03)。

本研究结果提供了一个可以评估长QT综合征患者5年致死性心律失常事件发生的体系,并指出纳多洛尔可能是唯一能降低患者心律失常发生率的β受体阻滞剂。
