冠状动脉再狭隘(coronary restenosis)大多是由经皮冠状动脉介入术(Percutaneous Coronary Intervention,PCI)与心脏支架术后重生内皮安排反常增生引起的血管再次狭隘,严重影响了PCI与支架的治愈率,现已经成为国内外研讨的热门[1]。本文选用文献计量学办法,对近5年来宣布在PubMed数据库中有关冠状动脉再狭隘的文章进行计算剖析,总结当时该主题的研讨热门,为展开深化研讨供给参阅依据。

3评论

依据聚类树状剖析图,能够得知现在对冠状动脉再狭隘的研讨首要会集在以下几方面:①心脏导管及包被资料与冠状动脉再狭隘的联系。有报导称[2-3]药物洗脱支架是动脉堵塞的有用医治办法,经过按捺血管平滑肌细胞向内膜的搬迁和增殖,能够大大下降再狭隘的发作率,并将新式的纳米技能运用到药物洗脱支架上。而Sotomi等[4]以为,药物洗脱支架虽然有较好的临床运用,可是仍旧没有解决永久性金属冠状动脉支架的一切局限性,因而生物可吸收支架应需而生,并具体报导了生物可吸收支架基本特征和临床成果,总结了生物可吸收支架的当时局限性及其可能的解决方案。②可吸收内固定支架与冠状动脉再狭隘的联系。生物可吸收内固定支架最早由Alt等[5]报导。最新的研讨[6]标明生物可吸收支架有助于康复生理性血管活性,削减冠状动脉再狭隘的构成。③运用冠状动脉造影术对冠状动脉再狭隘进行医学确诊。Murata等[7]报导运用冠状动脉造影术能够调查支架术后,内膜的成长状况,对冠状动脉再狭隘的发作进行猜测。④外科对冠状动脉再狭隘的影响。Roubin等[8]最早对由手术引起的冠状动脉再狭隘病因进行了总述,并以为应结合动脉造影和血液动力学成果一起断定该类患者是否合适进行外科手术。在欧洲,紫杉醇涂层气球率先在临床得到运用,该技能有望削减外周血和冠状动脉的再狭隘[9]。⑤冠状动脉再狭隘临床常用支架包被医治药物。Kalra等[10]研讨者以为第二代依维莫司洗脱支架优于第一代紫杉醇和西罗莫司洗脱支架,生物可吸收支架与第二代药物洗脱支架比较,现在并没有表现出更好的效果。而Codner等[11]研讨者则以为紫杉醇洗脱支架在糖尿病患者的PCI手术中具有更好的安全性和有用性。⑥运用与光学相关的断层扫描办法研讨冠状动脉再狭隘构成的病因学。Jinnouchi等[12-13]运用光学相关的断层扫描办法,关于药物洗脱支架植入后构成的冠状动脉再狭隘病因学进行研讨,并运用光学相关的断层扫描技能评价冠状动脉再狭隘不同阶段安排之间的特征与差异。⑦PCI术后不良反应引起的冠状动脉再狭隘。支架血栓构成(ST)是PCI的潜在危及生命的并发症,也是引起冠状动脉再狭隘的原因之一。Malik等[14]最新报导称该研讨团队开发一个评分体系来猜测ST后PCI的危险,这个加权评分体系可能有助于剖析ST危险,并对患有PCI的患者进行个体化抗血小板医治。⑧血液冠状动脉再狭隘的联系。Gabbasov等[15]最新研讨标明运用CD45+阳性血小板(CD45+血小板)目标评价患有安稳冠状动脉疾病(CAD)患者植入药物洗脱支架(DES)后冠状动脉再狭隘开展状况。Shah等[16]报导称抗血小板凝聚药物滥用会加剧支架内血栓构成胡危险。⑨心肌梗死患者PCI术后与冠状动脉再狭隘的联系。心肌梗死患者PCI术后有发作冠状动脉再狭隘的危险,因而要对此类患者的血管成形(剩余狭隘百分比)及血管病变(缓慢彻底阻塞)进行长时间预后调查[17]。⑩冠状动脉再狭隘的遗传学研讨。Kang[18]等研讨报导称,除变老、吸烟和糖尿病外,越来越多的研讨发现遗传和表观遗传要素在再狭隘中起重要作用,并回忆了再狭隘发展的遗传和表观遗传要素,有助于断定PCI术后再狭隘患者的遗传危险要素。

综上所述,可得呈现在关于冠状动脉再狭隘的研讨热门会集在病因、确诊、防备、遗传等方面,以上研讨热门为临床及根底研讨人员的深化科研供给了方向。endprint
