Brief summary
Polymer carried by drug-eluting stents may increase inflammatory response and thrombosis. Our previous study showed that polymer-free rapamycin-coated stents brings dose-dependent reduction in restenosis. This prospective, multicenter, randomized controlled clinical trials aimed to explore efficacy and safety of the YUKON drug eluting stent in diffuse coronary artery disease.
Interventions
Concentration of rapamycin is 2.5%
Concentration of rapamycin is 1.5%
