Primary study design	Interventional
Study design	Randomised, active controlled, parallel group, single centre trial
Secondary study design	Randomised controlled trial
Scientific title	Cypher drug-Eluting stent: a Zwolle Acute myocardial infarction Randomised trial
Study acronym	CEZAR
Study objectives	The study is designed to demonstrate superiority of Cypher stent based on the assumption that at follow-up angiography the late loss is at least 0.15 mm smaller than the mean late loss when the Taxus stent is used.
Ethics approval(s)	Ethics approval received from the local medical ethics committee
Health condition(s) or problem(s) studied	Acute myocardial infarction
Intervention	Percutaneous Coronary Intervention using either the Bx VELOCITYTM stent coated with rapamycin (Cypher) or the TaxusTM stent coated with Paclitaxel.
Intervention type	Other
Primary outcome measure(s)	Major adverse cardiac clinical events (death, re-infarction, target vessel revascularisation) at one, nine and 12 months after treatment.
Key secondary outcome measure(s)	Late lumen loss at nine months follow-up by quantitative coronary angiography
Completion date	01/12/2006

Participant type(s)	Patient
Age group	Not Specified
Sex	Not Specified
Target sample size at registration	352
Key inclusion criteria	1. Patients with acute myocardial infarction, presenting within six hours after symptom-onset, or those presenting between six and 24 hours if persisting chest pain associated with clinical evidence of on-going ischaemia occurs 2. Culprit lesion in a native coronary artery, suitable for stenting 3. Lesion length of less than 30 mm, located in a vessel of more than 2.5 mm 4. Able to deliver the stent to target lesion (absence of diffuse disease or excessive proximal vessel tortuosity) 5. Absence of no-reflow or extensive thrombus throughout vessel
Key exclusion criteria	1. Women of child-bearing potential 2. Severe hepatic or renal disease 3. Previous participation in the study 4. Life expectancy of less than one year 5. Factors making follow-up difficult 6. Acute myocardial infarction pre-treated with thrombolysis 7. Unprotected left main disease or single remaining vessel 8. Target lesion in a bifurcation with a large side-branch 9. Known sensitivity to aspirin or coumarin 10. Unable to provide informed consent
