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 may prevent these complications.

Condition Intervention Phase
Coronary Artery Disease Device: Yinyi stent Phase 2 Phase 3

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Safety and Efficacy Registry of Yinyi Polymer-free Paclitaxel-eluting Stent

Further study details as provided by Shanghai Jiao Tong University School of Medicine:

Primary Outcome Measures:
  • late lumen loss [ Time Frame: 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 Outcome Measures:
  • major adverse cardiac events [ Time Frame: 12 months ]
    including cardiac death, re-infarction, and target vessel revascularization

Estimated Enrollment: 200
Study Start Date: May 2010
Estimated Study Completion Date: December 2011
Estimated Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
