Study information

Scientific title



Study hypothesis

In patients presenting with a non-ST elevation acute coronary syndrome with (new) ST segment depression and/or positive troponin-T, who undergo PCI, treatment with a dexamethason coated stent will reduce the incidence of restenosis at 6 month follow-up angiography.

Patient information sheet


Unstable Angina Pectoris, acute coronary syndrome


Angiography and Revascularisation (PCI) after 24 hours pre-treatment with Tirofiban compared to Angiography after Pre-Treatment with Clopidogrel in High Risk Patients with Unstable Angina.

Intervention type



Not Specified

Drug names

Primary outcome measure

The Tirofiban strategy results in a smaller enzymatic infarct size, compared to the Clopidogrel strategy.

Secondary outcome measures

1.Enzymatic Infarct Size (LDHQ72)

2. Hospital Stay - Total duration in hospital in days, including admission and discharge day
Do Dexamethason-coated Stents Decrease the incidence of Restenosis in patients with an Acute Coronary Syndrome?

3. Clinical endpoints
3.1 Death - Total mortality will be assessed at 30 days follow-up.
3.2 Myocardial Infarction
a. Early MI in patients presenting with CKmb > upper limit of normal.
b. Early MI in patients presenting with CKmb not exceeding the upper limit of normal
c. Late MI in patients whose CKmb has returmed to (or has remained) normal.
d. MI in patients who underwent CABG.
3.3 Stroke - All (hemorrhagic and non-hemorrhagic) strokes must be confirmed by CT scan examination and after consultation of a neurologist.
3.4 Bleeding

4. Secondary Efficacy Parameter
4.1 The Tirofiban strategy results in a better patency of the culprit coronary artery before intervention.
4.2 Coronary Angiography. All angiography films will be evaluated by an independent core-laboratory (DIAGRAM, Zwolle, the Netherlands), without access to clinical data.
