Title: An International Randomised Trial of Early Versus Delayed Invasive Strategies in Patients With Non-ST Segment Elevation Acute Coronary Syndromes
Brief Summary: The timing of intervention study is a prospective, randomized, international, multicentre comparison of the relative efficacy, safety, and cost effectiveness of a management strategy of coronary angiography and intervention performed within 24 hours of randomization versus delayed coronary angiography and intervention in patients after 36 hours with acute coronary syndromes (ACS).


Options:
A: Inclusion Criteria:

1. Man over 18 or non-pregnant woman over 18.
2. Patient hospitalized for severe acute coronary syndrome. To be selected patients will need to have at least 2 criteria for acute coronary syndrome AND a TIMI score \> 3 for severity of ACS.

   ACS is defined by at least two of the following diagnostic criteria :
   * ischemic symptom
   * electrocardiographic abnormalities in the ST segment (depression or transitory elevation of at least 0.1 mV), or in the T waves, at least in two contiguous leads positive troponin (as defined locally).

   Severity of ACS is defined by a TIMI score \> 3
3. indication for catheterization agreed and possible within the following 8 hours.
4. signed consent form

Exclusion Criteria:

1. Patients that would require immediate catheterization for ongoing refractory ischemia, major arrhythmias, or hemodynamic instability are not eligible for the study.
2. Anticoagulant therapy with antivitamin K within 5 days preceding randomization
3. Thrombolytic therapy during the preceding 24 hours
4. Upstream treatment by a GPIIb/IIIa inhibitor
5. ReoPro should not be administered to patients with known sensitivity to abciximab, to any component of the product or to murine monoclonal antibodies. Because inhibition of platelet aggregation increases the risk of bleeding, ReoPro is contra-indicated in the following clinical situations: active internal bleeding; history of cerebrovascular accident within two years; recent (within two months) intracranial or intraspinal surgery or trauma; recent (within two months) major surgery; intracranial neoplasm, arteriovenous malformation or aneurysm; known bleeding diathesis or severe uncontrolled hypertension; pre-existing thrombocytopenia; vasculitis; hypertensive or diabetic retinopathy; severe hepatic or severe renal failure.
6. Woman nursing
B: Inclusion Criteria:

1. Subject is \>18 years old with recent acute ST-elevation acute coronary syndrome (STEACS) requiring emergent coronary angiography.
2. Patient has no contraindication to percutaneous arterial access by both and transfemoral route.
3. Subject has been informed of the nature of the study and agrees to its provisions and has provided written informed consent as approved by the Institutional Review Board/Ethics Committee of the respective clinical site.
4. Patient and the treating physician agree that the subject will comply with all follow-up evaluations.

Exclusion Criteria:

1. Subject's age is \<18 years and he has no acute ST-elevation myocardial infarction (ST elevation of a least 0.1 mV in ≥2 extremity leads or at least 0.2 mV in ≥2 precordial leads).
2. Subject has had a recent stroke or TIA (\<4 weeks), irrespective of age.
3. Patient has an international normalized ratio (INR) \> 2.0, or other severe bleeding diathesis
4. The patient is pregnant or breastfeeding.
5. Known allergies to: aspirin, clopidogrel and ticlopidine, heparin, IIb/IIIa inhibitors, stainless steel, or contrast agent (which cannot be adequately premedicated).

7.Subject is currently participating in an investigational drug or device study that has not completed the primary endpoint or that clinically interferes with the current study endpoints.

8.Prior participation in this study.
C: Inclusion Criteria:

* A person who has been diagnosed with acute coronary syndrome and is to undergo a percutaneous coronary intervention.
* A person who is of the legal age of 18 and is mentally competent to provide a signed written informed consent.
* If a woman is of childbearing potential (i.e., before menopause), she must test negative for pregnancy and agree to use a reliable method of birth control.

Exclusion Criteria:

* A person who has had an ischemic stroke within the last 3 months or a hemorrhagic stroke at any time in the past.
* A person who has active internal bleeding or has a history of a bleeding disorder.
* Individuals who are at an increased risk of bleeding based on laboratory criteria evaluated by the treatment physician or on medication that can cause bleeding.
* A person who has liver disease; for example, cirrhosis.
* A person who has a condition such as alcoholism, mental illness, or is drug dependent.
* A person who has cardiogenic shock, a refractory ventricular arrhythmia, or congestive heart failure (class IV).
D: Inclusion Criteria:

1. Patients presenting or admitted to hospital with symptoms suspected to represent an acute coronary syndrome (unstable angina or MI without persistent ST elevation) i.e., clinical history consistent with new onset, or a worsening pattern, of characteristic ischemic chest pain or ischemic symptoms occurring at rest or with minimal activity (lasting longer than five minutes or requiring sublingual nitroglycerin for relief of the pain)
2. Able to randomise within 24 hours of the onset of the most recent episode of symptoms
3. At least two of the three following additional criteria:

   * Age more than or equal to 60 years
   * Troponin T or I or Creatine Kinase - Myocardial Bands (CK-MB) above the upper limit of normal for the local institution
   * ElectroCardioGram (ECG) changes compatible with ischemia (i.e., ST depression at least 1 mm in two contiguous leads or T wave inversion mroe than 3 mm or any dynamic ST shift or transient ST elevation)
4. Written informed consent dated and signed

Exclusion Criteria:

1. Age less than 21 years
2. Not a suitable candidate for revascularisation
3. Co-morbid condition with life expectancy less than six months
