Coronary Artery Disease
Conditions
Brief summary
Drug-eluting stents effectively reduce restenosis but may increase late thrombosis and delayed restenosis. Persistent polymer could be responsible. Local delivery of paclitxel from a polymer-free Yinyi stent (Dalian Yinyi biomaterial research and development co.ltd) may prevent these complications.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| late lumen loss | 12 months | Late luminal loss was defined as the difference between the minimal luminal diameter immediately after the placement of the stent and the minimal luminal diameter at 12-month angiographic follow-up. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| major adverse cardiac events | 12 months | including cardiac death, re-infarction, and target vessel revascularization |
