JACC:治疗阵发性房颤有效新方法—热球囊消融

2016-12-20 fsy MedSci原创

目前医学上已建立逐点导管消融方法治疗药物难治性阵发性房颤(PAF)。然而,这种疗法是比较耗时的,需要更好的技术来实现完全的肺静脉(PV)隔离,并且这种疗法还伴有严重的并发症。这项研究的目的是评估与抗心律失常药物治疗(ADT)相比,热球囊消融(HBA)治疗PAF的安全性和有效性。研究人员在日本进行了一项前瞻性多中心随机对照研究。具有抗心律失常药物难治性症状性PAF(I级至IV级)的患者以2:1的比例

目前医学上已建立逐点导管消融方法治疗药物难治性阵发性房颤(PAF)。然而,这种疗法是比较耗时的,需要更好的技术来实现完全的肺静脉(PV)隔离,并且这种疗法还伴有严重的并发症。

这项研究的目的是评估与抗心律失常药物治疗(ADT)相比,热球囊消融(HBA)治疗PAF的安全性和有效性。

研究人员在日本进行了一项前瞻性多中心随机对照研究,具有抗心律失常药物难治性症状性PAF(I级至IV级)的患者以2:1的比例随机接受HBA或ADT治疗,研究人员在可比较的9个月随访期内评估有效性。

在17个治疗中心,共100例患者接受HBA治疗,共有43例患者接受ADT治疗。HBA手术使得98.0%(392/400)的PVs得到急性完全PV隔离,HBA组93.0%(93/100)的患者达到急性完全PV隔离。经过9个月有效评估期后,HBA组慢性成功率(n=100)为59.0%,ADT组为4.7%(n=43;p<0.001)。主要并发症的发生率为11.2%(134例患者中的15例患者)。PV狭窄(>70%)和短暂性膈神经损伤的发生率分别为5.2%和3.7%。平均透视时间为49.4±26.6分钟(n=134),平均手术持续时间为113.9±31.9分钟(n=133)。

这项研究表明,对于治疗PAF患者,HBA要优于ADT疗法,并且安全性较好。

Stroke:阵发性房颤不增加卒中的风险

背景和目的:房颤(AF)类型和卒中的关系存在争议。尽管许多研究表明阵发性AF(PAF)和持续性或永久性房颤与卒中发生的风险一致,最近研究表明PAF与卒中发生风险较低相关。在亚洲人群众PAF与卒中风险之间的相关性数据也是非常有限的。方法:日本一项基于社区的房颤患者的调查研究,将房颤分为两类:PAF或持续性房颤。研究者比较PAF(n=1588)和持续性房颤(n=1716)临床事件的发生。结果:一般情况

NEJM:治疗阵发性房颤,射频消融比球囊消融更合适

目前指南推荐使用导管消融术肺静脉隔离治疗药物难治性阵发性心房颤动。射频消融是最常用的方法,并且球囊消融是第二个最常用的技术。原始出处:Karl-Heinz Kuck,Josep Brugada,Alexander Fürnkranz,et al.Cryoballoon or Radiofrequency Ablation for Paroxysmal Atrial Fibrillation,NEJ

Int J Cardiol:阵发性房颤卒中死亡率较低(FibStroke研究)

背景:最近有研究报道,与慢性房颤相比,阵发性房颤(AF)患者有较低的血栓栓塞发生,预后较好。研究者旨在探讨阵发性房颤和慢性房颤患者缺血性事件的发生的差异。方法: Fibstroke研究是一项横断面观察性多中心注册研究,受试者为芬兰四个医院2003-2012年出院登记记录中缺血性卒中、TIA(短暂性脑缺血发作)或颅内出血伴房颤患者。共1448例阵发性房颤和1808例慢性房颤患者,共有707例患者TI

JAHA:饮酒频率会影响阵发性房颤患者导管消融预后

饮酒的频率可能与阵发性房颤患者首次接受导管消融治疗后房颤复发有关,但它可能不会影响末次导管消融治疗的预后结局。

PLoS One:阵发性房颤预测分数研究

阵发性心房颤动(pAF)是脑卒中的主要危险因素,但经常不易发现。预测阵发性房颤的存在,研究者开发了基于超声和常规心脏评估的临床参数建立模型分数。该分数可以很容易地应用于临床实践,并可能提高pAF的早期检测。总的来说,采集1000例窦性心律(SR;n = 728),pAF(n = 161)和cAF(n = 111)47项超声心动图及其它临床参数。研究者者应用Logistic模型分类pAF和SR,减少

Stroke:卒中患者中,持续性房颤比阵发性房颤患者有更高的缺血性事件风险

对于预防二级卒中的方法,阵发性和持续性(或永久性)房颤(AF)之间的区别还没有被充分考虑过。该研究的目的是评估大多数持续性和阵发性房颤患者(曾有过缺血性卒中或短暂性脑缺血发作)的抗凝治疗临床结果的差异性。来自日本的研究人员使用了1192例非瓣膜性房颤患者的数据,这些患者患有急性缺血性卒中或短暂性脑缺血发作,并且已经在SAMURAI-NVAF研究进行了注册(紧急危险因素评估和改善非瓣膜性房颤卒中管理
