The use of drug-eluting stents (DESs) dramatically reduced in-stent restenosis. However, the increasing use of these stents has raised concern about their potential thrombogenicity. Indeed, the particularity of DES thrombosis compared with bare metal stent thrombosis is a high rate of late thrombosis. Antiplatelet therapy is efficient in preventing DES thrombosis. However, this therapy could be optimized and may be improved in the future. This article will review the mechanisms and the epidemiology of stent thrombosis. Then, we will summarize the antiplatelet therapeutic strategies used to prevent stent thrombosis and especially DES-associated thrombosis. Finally, we will present some data with regard to potential advantages and pitfalls in DES thrombosis prevention using novel antiplatelet agents currently under development, as well as future stent designs with improved healing properties.
药物洗脱支架(DES)的使用显著降低了支架内再狭窄的发生率。然而,这些支架使用的增加引发了人们对其潜在血栓形成性的担忧。事实上,与裸金属支架血栓形成相比,DES血栓形成的特殊性在于晚期血栓形成率较高。抗血小板治疗在预防DES血栓形成方面是有效的。然而,这种治疗方法可以进一步优化,并且未来可能会有所改进。本文将综述支架血栓形成的机制和流行病学。然后,我们将总结用于预防支架血栓形成,特别是与DES相关血栓形成的抗血小板治疗策略。最后,我们将介绍一些关于目前正在研发的新型抗血小板药物在预防DES血栓形成方面的潜在优势和缺陷的数据,以及具有改善愈合特性的未来支架设计。
