冠状动脉金属支架术后再狭窄的研究进展

金属支架在冠状动脉疾病介入治疗中发挥着越来越重要的作用,再狭窄是困扰这一技术发展的主要原因之一,目前随着对其产生机理的逐渐明了,有关再狭窄防治研究日益活跃,并取得了令人瞩目的成绩。最新研究显示,药物涂层支架在预防再狭窄中较裸支架具有独特的应用价值,大大降低了再狭窄发生率,应用前景广阔,但远期疗效尚待进一步观察。

Progress in the study of coronary artery in-stent stenosis

Coronary stenting played an increasingly important role in the interventional treatment of coronary artery disease. However, in-stent restenosis is one of the major causes that limited the development of the technology. As the mechanism of in-stent restenosis became more and more clear, studies on the prevention of in-stent restenosis became increasingly active, and had gained remarkable achievements. The latest research indicates that drug-eluting stents had more unique application value in the prevention of restenosis, as compared with uncoated coronary stents. Drug-eluting stents significantly reduced the incidence of restenosis, and had broad prospects for application, but long-term treatment outcome required further observation.
