Study hypothesis
The hypothesis of this study is that there is more complete stent strut coverage in the polymer free rapamycin eluting 'Yukon' stent (Translumina), compared with the durable polymer based rapamycin eluting stent 'Cypher' (Cordis) using optical coherence tomography at 3 months post implantation.
Ethics approval
Approval from UK Central Office of Research Ethics Committees (COREC) on 4th October 2006 (ref: 06/Q0404/61)

Condition
Coronary artery disease
Intervention
In brief all patients will be undergoing drug eluting intracoronary stent deployment as clinically indicated. Patients will be randomly allocated to receive a Yukon (rapamicin eluting polymer free) or Cypher (rapamicin eluting polymer coated) stent using standard clinical protocols according to the discretion of the implanting cardiologist. Patients will be systematically re-catheterised at 90 days and undergo optical coherence tomography.

Primary outcome measures
Comparison of binary stent strut coverage between the Yukon (rapamicin eluting polymer free) and Cypher (rapamicin eluting polymer coated) groups at 90 day optical coherence tomography.
Secondary outcome measures
Comparison of mean neointimal thickness between the Yukon (rapamicin eluting polymer free) and Cypher (rapamicin eluting polymer coated) groups at 90 day optical coherence tomography.
