JACC:哪种遗传性心脏病心脏性猝死常见?

2020-05-31 岱西 中国循环杂志

近日发表在JACC上的一项研究发现,心脏性猝死患者心肺复苏后明确的遗传性心脏病,最常见的是长QT综合征;40岁以上人群,最常见的则是肥厚型心肌病。

近日发表在JACC上的一项研究发现,心脏性猝死患者心肺复苏后明确的遗传性心脏病,最常见的是长QT综合征;40岁以上人群,最常见的则是肥厚型心肌病。

在这项研究中,225例因心脏性猝死心脏复苏病例中, 51%有遗传性心脏病。

其中,长QT综合征最为多见,其次是肥厚型心肌病和Brugada综合征,分别占42%、24%和14%。

725例遗传性心脏病先证者中,出现心脏性猝死后心肺复苏最常见的是,儿茶酚胺敏感性室性心动过速,其次是Brugada综合征和致心律失常型右室心肌病,占比分别为53%、33%和25%。

此外,研究还发现,有40%的事件发生于日常活动中,30%发生于运动中,12%有并发症,9%发生于睡眠中,8%由药物诱发,2%由情感诱发。

在24岁以下人群中,长QT综合征和儿茶酚胺敏感性室性心动过速最为多见,占比77%;24岁以上人群中,心肌病和Brugada综合征多见,占比64%;40岁人群,则是肥厚型心肌病最多见,占33%。

研究者还在98例患者中进行了基因检测,其中48例患者确诊遗传性心脏病,诊断年龄大致随年龄增长而占比降低:

1~14岁,遗传性心脏病占78%;15~24岁占53%;25~39岁占54%;大于40岁,占26%。

这项研究的数据来源于新西兰国家心脏遗传病注册中心2002~2018年收集的资料。

心源性猝死(SCD)是肥厚型心肌病(HCM)最严重的并发症。年轻HCM患者的SCD风险更高,这使得SCD更具破坏性。植入式心脏转复除颤器(ICD)的使用能挽救患者的生命,因此,评估HCM患者的猝死风险成为当务之急。HCM患者SCD发生率较低,任何危险分层方法均存在低阳性预测值的困扰。与心力衰竭患者的情况类似,植入ICD的部分HCM患者不会出现有效干预,这种不必要的植入也可视作为挽救年轻生命所付出的
