心血管植介入体表面抗凝涂层近十年进展

A Critical Review on Anticoagulant Coatings on Cardiovascular Implants in the Past 10 Years

  • 摘要: 心血管植介入体已被广泛用于治疗各种心血管疾病. 然而,植介入体表面和血液之间的接触会导致血栓,进而显著增加了血栓疾病的发病率和死亡率. 为降低血栓风险,在植介入体表面修饰抗凝涂层是预防血栓的常用方法. 本文中作者综述了近十年中不同心血管植介入体表面的抗凝涂层技术,重点回顾了应用于四种典型的心血管植介入体(包括人工心脏瓣膜、血管支架、心室辅助装置和导管)的抗凝涂层的进展. 最后,总结了每种植介入体表面的理想设计,并展望了心血管植介入体表面抗凝涂层技术的未来,对推进心血管植介入体的设计开发和应用具有重要意义.

     

    Abstract: Cardiovascular implants have been widely used as a treatment for various cardiovascular diseases. However, the contact between implant surface and blood will cause thrombus that leads to significant morbidity and mortality worldwide. To reduce the risk of thrombus, immobilizing anticoagulant coatings on the implant surface is a common method to realize anticoagulation. In this review, we focus on the anticoagulant coatings on different cardiovascular implants in the past 10 years. We review the advance on the anticoagulant coatings of four typical cardiovascular implants including artificial heart valves, vascular stents, ventricular assist devices, and catheters. In the end, we conclude the ideal design for each implant and look ahead to the future of the cardiovascular anticoagulant coatings. It is of great significance to improve the design and application of cardiovascular implants.
