JACC:PCI术后合并分叉病变,常规支架与专用分叉支架如何选择?

2015-02-24 张旭栋 MedSci原创

有症状的冠心病患者,在行径皮冠状动脉介入术后,经常会发生分叉病变,其比率接近15%-20%。尽管支架技术目前已经有了很大的进展,然而,分叉病变对于心脏疾病的介入治疗仍然是一项重大的挑战,其与围手术期心肌梗死,支架内血栓,远期再狭窄有着密切的联系。虽然已经有了很多对应的技术与治疗策略,目前的主流方案仍然是:主干病变首先治疗,分叉病变需要时再进行治疗。几项小的随机研究显示,对于




有症状的冠心病患者,在行径皮冠状动脉介入术后,经常会发生分叉病变,其比率接近15%-20%。尽管支架技术目前已经有了很大的进展,然而,分叉病变对于心脏疾病的介入治疗仍然是一项重大的挑战,其与围手术期心肌梗死,支架内血栓,远期再狭窄有着密切的联系。虽然已经有了很多对应的技术与治疗策略,目前的主流方案仍然是:主干病变首先治疗,分叉病变需要时再进行治疗。几项小的随机研究显示,对于分叉病变植入专用分叉支架具有一定的优势。加拿大魁北克蒙特利尔大学医学院,纽约哥伦比亚大学医学中心Philippe Généreux博士等人就此研究了常规支架(Provisional Stenting)与专用支架(Tryton Stent)的比较,成果发表在2月份Journal of the American College of Cardiology期刊上。
背景:有症状的冠心病患者经皮冠状动脉介入治疗后经常会出现分叉病变。对于侧枝的治疗,目前证据建议进行保守治疗(球囊扩张术后使用常规支架)。
目的:TRYTON(前瞻性,单盲,随机对照研究,以评估冠脉主枝和侧枝进行药物洗脱支架治疗的安全性和效益)分叉试验,旨在比较使用专用的分叉支架或侧枝球囊扩张术(扩张后使用常规支架)对于分叉病变的疗效。
方法:我们对植入主要血管支架后合并分叉病变的患者,随机行常规支架术或分叉支架术。主要终点为靶血管病变(TVF)(心源性死亡,靶血管心肌梗死和靶血管血运重建)。次要终点血管造影是9月后侧枝血管梗死直径的百分率。
结果:我们随机从58个中心选取704例具有冠脉分叉病变的患者(30个中心来自欧洲,28中心来自美国)。9个月后,分叉支架组TVF为17.4%与常规支架组为12.8%相比(p=0.11),围手术期心肌梗死率少许增高(13.6% vs. 10.1%, p = 0.19),但仍不具有显著优势。分叉支架组与常规支架组相比,侧枝梗死直径有所下降(31.6%:38.6%,P=0.002,有优势),而9个月随访显示,其再狭窄率无明显差异(直径狭窄≥50%)(22.6%:26.8%,P =0.44)。

结局:非左主干冠状动脉分叉病变中,常规支架仍然应该作为首选治疗策略。

JAMA子刊:STEMI患者无法及时行PCI 可选转院前溶栓治疗!

美国一项研究表明,对于无法及时行直接经皮冠脉介入(pPCI)的患者,当及时再灌注治疗获益超过出血风险时,可选择医院转诊前行溶栓治疗并继之以血管造影。论文12月8日在线发表于《美国医学会杂志·内科学》(JAMA Intern Med)。 此项研究确认了22481例适宜行pPCI或溶栓治疗且接受医院间转诊的ST段抬高型心肌梗死(STEMI)患者,并在上述患者中评估了估计的医院间转诊时间与再关注策略的

下一个时代:生物可降解支架

下一个时代:生物可降解支架 葛均波院士、戴宇翔医师介绍,近年来,生物可降解支架及聚合物可降解药物洗脱支架逐渐成为冠心病介入治疗中的最大亮点之一。由于此类支架缓慢降解,并完全被组织吸收,血管结构及其舒缩功能完全恢复至自然状态,其优势在于:非永久置入体内,减少长期存留对血管的刺激和炎症反应;有可能减少双联抗血小板药物治疗时间;利于再次介入治疗。因而,完全可降解支架被称为冠脉介入的“第四

JACC Cardiovasc Interv:实时超声引导有助于提高挠动脉途径PCI成功率

  目的:这项研究主要用于评估经超声引导的挠动脉途径PCI。 背景:超声引导已经证明有利于血管通路经挠动脉心导管插管,但是并没有多中心随试验。 方法:我们进行了一项前瞻性多中心随机对照实验,698例患者接受经桡动脉试验心导管检查。患者随机选择触诊方式挠动脉插管或者实时超声引导插管(351例选择触诊,347例选择超声引导)。主要终点是需要插管尝试次数,一次成功率和插管时间。 结

PCI术后双抗到底需多久?

PCI术后DAPT时间:仍无定论 经皮冠状动脉介入治疗(PCI)置入药物洗脱支架(DES)后,由于术后血管损伤修复、支架内皮覆盖需要一定的时间,因而有效的双联抗血小板治疗(DAPT)十分必要,以预防晚期或极晚期支架内血栓形成,减少缺血性心血管事件的发生。 上海交通大学医学院附属瑞金医院沈卫峰教授介绍,近年来人们致力于探讨DAPT最佳时间间期,以达到获益与出血风险的平衡。目前大多

Circ Cardi Interv:警惕冠脉导丝涂层脱落致远端栓塞

荷兰一项研究表明,经皮冠脉介入治疗(PCI)后冠脉导丝亲水涂层脱落导致远端栓塞的情况较为常见。论文1月23日在线发表于《循环:心血管介入》(Circulation: Cardiovascular Interventions)。 此项研究对205例血栓抽吸物和40例尸检样本进行了评估,以明确冠脉导丝亲水涂层脱落并栓塞远端微血管系统的发生频率。 结果显示,45%的血栓切面存在异物,

BMJ:患者对经皮冠状动脉介入治疗的获益过于乐观

专家们一致同意, 与合理的药物治疗相比, 经皮冠状动脉介入治疗( PCI ) 不能延长稳定性冠心病患者的存活时间, 也不能降低心肌梗死的发生危险, 但其对改善心绞痛症状的确有效。 因此指南建议只有当稳定性冠心病患者接受适当药物治疗后仍存在不可耐受的症状, 或无法耐受药物治疗时, 才推荐PCI 。 在链接的一篇文章中, Kureshi 等报道在美国10 家医院进行的调查中, 绝大
