Title: Clopidogrel Or Metoprolol in Myocardial Infarction Trial
Brief Summary: COMMIT/CCS2 is a large randomised trial of the effects of clopidogrel plus Aspirin versus Aspirin alone in acute heart disease. Patients presenting within 24 hours of the onset of suspected acute MI were potentially eligible provided they were thought to have ST elevation or other ischaemic ECG abnormality with no clear indication for, or contraindication to, trial treatment. All patients were to be given 162 mg ASA daily and, in addition, 75 mg clopidogrel daily or matching placebo for 4 weeks or until prior discharge or death. (Patients were also randomised separately in a 2 X 2 factorial design between metoprolol versus placebo.) The two main study endpoints are death and the composite outcome of death, non-fatal reinfarction or stroke during the scheduled treatment period in hospital.


Options:
A: Inclusion Criteria:

* Patients presenting with ST elevation, left bundle branch block or ST depression within 24 hours of the onset of the symptoms of suspected acute MI

Exclusion Criteria:

* Persons with moderate or severe liver disease
* Persons who have already been treated with an invasive (angioplasty) procedure for the current episode of ACS
* Persons who are being treated with blood clotting agents that cannot be stopped
C: INCLUSION:

Be at least 45 years old and comply with at least one of the four categories of inclusion criteria:

* Combination of atherothrombotic risk factors (2 major or 3 minor or 1 major + 2 minor risk factors among those listed below)

Major atherothrombotic risk factors

* Type I or II diabetes (under drug therapy)
* Diabetic nephropathy
* Ankle brachial index (ABI) \< 0.9
* Asymptomatic carotid stenosis \>= 70%
* At least one carotid plaque as evidenced by intima-media thickness (IMT)

Minor atherothrombotic risk factors

* Primary hypercholesterolemia
* Current smoking \> 15 cigarettes per day
* Male \>= 65 years
* Female \>= 70 years

and/or

* Documented cerebrovascular disease (TIA or IS within 5 years) and/or
* Documented coronary artery disease (stable angina with documented multivessel coronary disease, previous documented MI, multivessel PCI or CABG within 1 year, multivessel CABG older than 1 year associated with current angina) and/or
* Documented symptomatic PAD

EXCLUSION:

* Absolute indication for the use of clopidogrel, high-dose aspirin (\>162 mg), NSAIDs, or oral anti-thrombotic drugs
* Absolute contraindication to the use of clopidogrel or aspirin
* Clinical conditions likely to interfere with follow-up leading to inability to complete the trial
D: Inclusion criteria:

Male or female subjects 55 year or older who have suffered an ischemic stroke within the past 90 days and who meet all other inclusion criteria. Include also patients of ages 50 - 54 years and/or 90 to 120 days after the qualifying stroke provided the patient has at least two of the following additional risk factors:

* Diabetes mellitus
* Hypertension (systolic BP ¿ 140 or diastolic BP ¿ 90)
* Smoker at time of qualifying stroke
* Obesity (BMI\>30; BMI=weight (kg)/\[height (m)\]2)
* Previous vascular disease (stroke, MI, or peripheral arterial disease prior to qualifying stroke)
* End-organ-damage (retinopathy, LVH, or microalbuminuria)
* Hyperlipidemia

Exclusion criteria:

hemorrhagic stroke (must be ruled out by imaging);unable to give informed consent; known brain tumor, severe renal or hepatic insufficiency, current active peptic ulcer disease, severe coronary artery disease including unstable angina pectoris or an MI within the previous 3 months,or history of a hemostatic disorder or systemic bleeding ;hyperkalemia;uncorrected volume or sodium depletion; pre-stroke history of dementia;modified Rankin score greater than 4;qualifying stroke induced by surgical or cardiovascular procedure;uncontrolled hypertension at entry above 180/110 mmHg (goal BPs are lower); SBP 120 mmHg or less for hospitalized patients; currently taking an ARB and not able or willing to switch to alternative; required or planned continuing treatment with antithrombotics or anticoagulants including heparin or warfarin or non-study platelet inhibitors; syndrome of asthma, rhinitis and nasal polyps;scheduled for major surgery, carotid endarterectomy, or carotid angioplasty (4 weeks post surgery is allowed);unlikely to be released from hospital following the qualifying stroke or presence of a severe disability likely to lead to being bedridden or demented or a non-vascular disease or condition which makes it unlikely that the patient will survive to the end of the trial; history of thrombocytopenia or neutropenia.
