临床上,部分心绞痛患者经过最佳药物治疗后仍不能满意控制症状,且因种种原因不适于冠脉介入治疗,此时治疗难度会非常大。根据刚刚正式发表的2期临床试验结果,应用冠状窦支架有望显著缓解患者心绞痛症状并改善生活质量。相关阅读:NEJM:顽固性心绞痛患者的福音来了

冠状窦支架是一种球囊膨胀式沙漏状特殊装置,置入冠状窦后可以增加局部血流阻力,进而增加缺血心肌的灌注压,缓解缺血相关症状。刚刚正式发表的COSIRA研究对这一技术做了初步探讨(N Engl J Med 2015;372:519)。该研究共纳入104例不适于冠脉介入治疗的难治性心绞痛患者(CCS心绞痛分级Ⅲ或Ⅳ级),随机分为治疗组(置入冠状窦支架)与对照组(假手术)。主要终点为治疗6个月后心绞痛CCS分解改善≥2级的患者比例。结果显示,与对照组相比,治疗组患者心绞痛症状得到了更为有效的控制,且生活质量也有显著改善。该研究结果为冠状窦支架技术展现了良好前景。

近年来,在心血管疾病的治疗领域,不断涌现出新的治疗技术(例如本研究中所应用的冠状动脉支架技术、治疗顽固性高血压的肾脏去交感神经术和髂动静脉分流术等)。虽然很多技术尚处于早期研发与临床前期的试验阶段,仍然为我们带来更多的新希望。与此同时,我们也应注意到,这些新技术尚需更长时间的探索与随访以及更多的设计严谨的随机化试验方能论证其有效性和安全性,因而据临床推广应用仍有很长的道路。特别是以破坏人体正常生理结构与功能为代价的治疗方法,应采取更为谨慎的态度,以免为患者带来远期不良危害。

JAMA Intern Med:稳定性冠心病者出现心绞痛与不良转归风险增加相关

法国一项研究表明,在稳定性冠脉疾病门诊患者中,心绞痛症状与不良心血管转归风险升高具有相关性。论文8月11日在线发表于《美国医学会杂志·内科学》(JAMA Intern Med)。 此项研究从CLARIFY登记系统中纳入了32105例伴有既往心梗、胸痛、心肌缺血和冠脉疾病征象以及既往血运重建的门诊患者,其中20291例接受无创性心肌缺血检测。主要转归为心血管相关性死亡和非致命性心梗。评估心

日本研究者称心绞痛有望通过超声波治疗

日本东北大学的研究小组20日宣布,他们开发出了利用超声波照射心脏来促进形成毛细血管的新方法,并且在动物实验中确认了效果。这一成果将有望促进开发出治疗心绞痛的新方法。 心绞痛是由冠状动脉供血不足引发的,以心肌急剧的、暂时缺血与缺氧引起的发作性胸痛或胸部不适为主要表现。治疗心绞痛时,除了药物治疗外,目前还可以采取给血管放入支架或进行搭桥手术,不过,有时支架和搭桥并不适用于重症患者,而且给身体造成的负担

Eur Heart J:硝酸盐类长期治疗未能改善VSA患者远期预后

日本一项研究表明,长期应用硝酸盐类联合钙拮抗剂(CCB)未能改善血管痉挛性心绞痛(VSA)患者远期预后;而且,接受多种硝酸盐类药物治疗的VSA患者发生心脏事件的风险可能增加。论文于9月4日在线发表于《欧洲心脏杂志》(Eur Heart J)。 此项研究共纳入1429例中位年龄为66岁的VSA患者,中位年龄66岁,男女性分别为1090例和339例。主要终点为严重不良心脏事件(MAC

TCT2014:生物可吸收支架与Xience支架同样安全有效

TCT 2014年会最新临床试验专场上发布的ABSORB II研究中期分析结果显示,与依维莫司洗脱金属支架(Xience)相比,依维莫司生物可吸收支架(Absorb BVS)可显著降低冠状动脉疾病患者的早期管腔获得,且两者在早期管腔获得方面的差异与支架置入后的即刻支架回缩无关。但是,二者对临床结局及心绞痛状态的影响并无差异。 自获得欧洲CE认证后,虽未进行与金属支架的随机对比,但Absorb B

NEJM:顽固性心绞痛患者的福音来了

顽固性心绞痛患者的福音来了背景许多有冠心病的患者并不适合使用血管再生药物进行治疗顽固性心绞痛,尽管这一措施符合治疗标准。我们使用了一个利用气囊膨胀原理、不锈钢、沙漏形、减少冠状窦的新设备,将该设备放置在一个冠状窦最集中狭窄的部位,增加冠状窦压力,血液也因此分配到缺血心肌,采用这个原理治疗顽固性心绞痛。方式实验参与人员为104位由加拿大心血管协会(CCS)评定心功能为三级或者四级和心肌缺血的患者(心
