冠状动脉内支架植入是目前广泛应用的冠心病治疗手段,但支架内狭窄和晚期血栓形成影响冠状动脉支架远期疗效和安全性,长期应用抗血小板药物所带来的不良反应以及经济上给患者造成的负担,这些都限制了冠状动脉支架的进一步应用。生物可吸收金属支架具有与裸金属支架相当的支撑力及良好生物相容性,可有效降低再狭窄率和血栓形成,临床应用前景十分广阔。 Coronary stent implantation is widely used in the treatment of coronary heart disease, but stent stenosis and advanced thrombosis affect the long-term efficacy and safety of coronary stents, long-term use of antiplatelet drugs caused by adverse reactions and to give Patient burden, which have limited the further use of coronary stents. Bioabsorbable metal scaffold with bare metal scaffold with comparable support and good biocompatibility, can effectively reduce the restenosis rate and thrombosis, clinical application is very broad.
