带有植入式心律转复除颤器(ICD)心肌梗死的幸存者尽管服用抗心律失常药物治疗,但发生复发性室性心动过速也非常频繁。解决这个问题最有效的管理方法是不确定的。

研究人员进行了一项多中心,随机,对照试验,涉及缺血性心肌病带有ICD的患者,这些患者尽管使用了抗心律失常药物,但还是患有室性心动过速。患者被随机分配接受继续服用基线抗心律失常药物治疗的导管消融(消融组)或升级抗心律失常药物治疗(升级治疗组)。在升级治疗组中,如果患者之前一直服用另外一种药物,则开始使用胺碘酮治疗。如果一直以来胺碘酮的剂量小于每天300毫克,则胺碘酮的剂量需要增加,如果一直以来剂量至少为每天300毫克,则加入美西律治疗。主要终点是死亡,24小时内记录三次或更多的室性心动过速(室性心动过速风暴),或适当的ICD电击的复合结果。

该研究共纳入259名患者,132例患者被分配到消融组,127例患者被分配到升级治疗组。在平均(±SD)27.9±17.1个月的随访过程中,消融组59.1%的患者和升级治疗组68.5%的患者发生主要终点(消融组危险比为0.72 ;95%置信区间,0.53至0.98; P=0.04)。死亡率没有显著的组间差异。消融组出现2例心脏穿孔和3例大出血,升级治疗组发生2例因肺部毒性作用的死亡,1例因肝功能障碍死亡。

在植入ICD缺血性心肌病,尽管使用抗心律失常药物治疗但仍然患有室性心动过速的患者中,接受导管消融的患者比那些接受升级抗心律失常药物治疗的患者有较低的死亡,室性心动过速风暴,或适当ICD电击的复合结果发生率。

JACC:BCSD或能治疗室性心动过速

  交感神经系统在室性心功过速中起到重要作用。左心去交感神经术(LCSD)能减少室性心动过速的发生及因严重室性心动过速导致的心脏性猝死。但当LCSD对抑制是室性心动过速无效时,再附加行右心去交感神经术可能是一个可选的方案。采用双侧心脏去交感神经术(BCSD)来治疗室性心动过速,在人体的安全性和可行性还不清楚。   研究者设计临床研究,以明确双侧心脏去交感神经术的对持续性室性心动过速的急诊控制作用

VT消融后早期NIPS预测晚期再发危险

  室性心动过速(VT)消融后的最佳终点尚未明确。近日,美国研究者在《美国心脏病学会杂志》(J Am Coll Cardiol, 2012; 59:1529-1535)发表的一项研究表明,当VT和结构性心脏病患者在消融结束时无VT或仅诱发非临床VT,或患者的症状不稳定而不能进行最终的刺激程序时,可以考虑在后续几天实施无创程序性刺激(NIPS)以进一

BMJ:延迟二次除颤治疗持续性VT/VF可增加患者的住院率

来自美国东部的一个卫生保健系统描述了第一和第二尝试除颤之间的时间间隔的趋势以及与此时间间隔与因持续性室性心动过速或心室颤动(VT / VF)而住院的患者结局之间的关系。

ESC 2015:新版室性心律失常和心脏性猝死指南重要更新抢先速看

8月29日,ESC对室性心律失常和心脏性猝死指南进行了重要更新,新版指南最新发表在European Heart Journal和ESC网站,这是继2006年版欧洲/美国的欧洲指南最新更新。这一指南旨在预防室性心律失常患者心源性猝死的发生。1.DNA分析应作为中青年猝死者验尸报告中的一个基本组成 明确中青年猝死者的遗传因素情况有助于快速诊断猝死的原因,对防止亲属中再次发生猝死有益。指南的制

Eur Heart J:射频消融适用于持续单一型室性心动过速治疗

欧洲一项研究表明,在持续单一型室性心动过速(SMVT)患者中,未置入ICD射频消融治疗所引起的心律失常性死亡发生率极低,并且复发通常为非致命性。论文于2月16日在线发表于《欧洲心脏杂志》(Eur Heart J)。【原文下载】 此项研究共纳入166例左室射血分数(LVEF)>30%且伴有结构性心脏病的耐受良好SMVT患者;受试者均在未置入ICD的情况下接受射频消融治疗。受试者平均年龄为62

Circulation:疤痕相关室性心动过速(VT)改良新终点

  研究显示,对于疤痕相关的室性心动过速(VT),明确局部异常心室活动(LAVA)并消除LAVA 是安全可行的,患者存活率更高,且可避免VT复发。该研究2012年4月4日在线发表于《循环》(Circulation)杂志。   导管消融治疗VT有效,而且在需要经常除颤的患者中特别有用,对于不能描记的或血流动力学不耐受的VT,有各种不同的基质改良技术。非诱导性是最常被使用的VT终点,但其有
