Endeavor R与Cypher R支架对直接PCI的STEMI患者安全有效

2012-05-06 王嘉玲 医学论坛网

  最近,北京朝阳医院的王乐丰在第10届中国介入心脏病学(CIT)大会最新临床试验与特色研究专场上公布的一项研究显示:Endeavor R西罗莫司与Cypher R佐他莫司洗脱支架对于直接经皮冠脉介入(PCI)治疗的ST段抬高型心肌梗死(STEMI)患者是安全有效的;随访12个月时,置入EndeavorR西罗莫司洗脱支架的再狭窄率及靶病变血运重建(TLR)率高于CypherR佐他莫司洗脱支架。

  最近,北京朝阳医院的王乐丰在第10届中国介入心脏病学(CIT)大会最新临床试验与特色研究专场上公布的一项研究显示:Endeavor R西罗莫司与Cypher R佐他莫司洗脱支架对于直接经皮冠脉介入(PCI)治疗的ST段抬高型心肌梗死(STEMI)患者是安全有效的;随访12个月时,置入EndeavorR西罗莫司洗脱支架的再狭窄率及靶病变血运重建(TLR)率高于CypherR佐他莫司洗脱支架。

  既往几项已发表的研究显示,药物洗脱支架(DES)用于直接PCI的STEMI患者安全有效,能降低再狭窄及主要心脏不良事件(MACE)的发生率。但这些研究没有针对性地评估Cypher R与Endeavor R之间的临床及血管造影终点。

  在此研究中,随访至1年时的患者达843例(97.8%)。6个月时 ,EndeavorR和CypherR的复合MACE分别为4.5%和3.5%(P=0.48),靶病变血运重建(TLR)率分别为1.3%和0.7%(P=0.35),支架再狭窄率分别为1.1%和0.2%(P=0.09),心梗发生率分别为0.4%和0.7%(P=0.61)。12个月时,Endeavor R和Cypher R的心源性死亡发生率分别为2.9%和2.1%(P=0.38),TLR发生率分别为2.1%和0.6%(P=0.05),支架再狭窄率分别为2.2%和0.2%(P=0.01),支架内血栓形成率分别为1.5%和1.3%(P=0.75),心梗发生率分别为1.3%和1.1%(P=0.78),卒中发生率分别为0.6% 和0.4%(P=0.68),出血发生率分别为1.7%和1.3%(P=0.24)。

EHJ:新一代药物洗脱支架的安全性明显更优

1月9日,《欧洲心脏杂志》(European Heart Journal)在线发表了瑞典冠状动脉造影和血管成形术登记库(SCAAR)的研究论文。研究显示,与老一代的药物洗脱支架(DES)和裸金属支架(BMS)相比,新一代DES经皮冠状动脉介入治疗的再狭窄、支架内血栓形成和死亡风险明显较低。 瑞典乌普萨拉大学的Giovanna Sarno博士及其同事在未经选择的大规模真实世界人群中对不同类型的新型

JACC:重复置入支架治疗药物洗脱支架(DES)再狭窄有效

 《美国心脏病学会杂志》(J Am Coll Cardiol)杂志近期在线发表了韩国学者的一项前瞻性研究,证实对于药物洗脱支架(DES)内的局灶型再狭窄病变,重复置入西罗莫司洗脱支架(SES)较切割球囊血管成形术能更有效地降低晚期管腔丢失和随后的再狭窄率。而对于弥漫型DES再狭窄病变,置入SES或依维莫司洗脱支架(EES)在血管造影和临床转归方面疗效相当。   DES发生支架内再狭窄(ISR)

同单纯置入BMS相比DEB预扩后置入BMS无临床效果优势(DEB-AMI研究)

    来自荷兰和意大利的DEB-AMI试验6个月随访发现,药物洗脱球囊预扩后置入裸金属支架(DEB加BMS)后造影结果并不优于单纯置入裸金属支架(BMS);药物洗脱支架(DES)造影结果比BMS或DEB加BMS更好。此外,和BMS相比,支架置入前以DEB预扩会导致更多的支架贴壁不良和覆盖不良,不过,该两种情况发生仍少于置入DES的患者。研究4月11日在线发表于《美国心脏病学会杂志》(

JACC:使用药物洗脱支架患者死亡风险低

一项发表于《美国心脏学会杂志》J Am Coll Cardiol杂志上的研究论文"Percutaneous coronary intervention and drug-eluting stent use among patients ≥85 years of age in the United States"证实:在直接经皮冠状动脉介入治疗中,虽然使用药物洗脱支架和裸金属支架的老年病人数显著下降

EHJ:支架贴壁不良影响远期转归

  瑞士学者的一项研究表明,在长期随访期间,药物洗脱支架(DES)置入后支架贴壁不良(ISA)与心肌梗死和极晚期支架血栓形成发生率升高相关。论文于2012年1月26日在线发表于《欧洲心脏杂志》(Euro Heart J)。   DES置入后的晚期ISA较裸金属支架(BMS)置入后更为常见,并且与血管超敏反应和支架置入后血栓形成(ST)。此项研究对伴有221处病变的194例患者进行了为期5年的前瞻

DES未能降低较大直径冠脉病变患者的TVR风险

  最近,美国学者的一项研究表明,在伴有较大直径冠脉病变的患者中,与金属裸支架(BMS)相比,药物洗脱支架(DES)未能降低靶血管血运重建(TVR)风险。论文发表于《美国心脏病学会杂志》[J Am Coll Cardiol 2012, 59:198]。   随机试验显示DES在降低TVR风险方面优于BMS,但此种获益随动脉直径增加而减弱。目
