Title: A Comparison of CS-747 and Clopidogrel in Acute Coronary Syndrome Subjects Who Are to Undergo Percutaneous Coronary Intervention
Brief Summary: The sponsors of this investigational drug are developing prasugrel (also known as CS-747) as a possible treatment for patients with acute coronary syndrome (heart attack or chest pain) who need, or are expected to need, a percutaneous coronary intervention (PCI; also called a balloon angioplasty). Prasugrel was compared with Clopidogrel to determine which drug is better at reducing deaths, future heart attacks, or stroke.


Options:
A: 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.
B: Inclusion Criteria:

Inclusion Criteria:

* Patients with NYHA class II, III, or IV and left ventricular ejection fractions less than or equal to 35%, on an ACE inhibitor (unless not tolerated) and on a diuretic.

Exclusion Criteria:
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:

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

* Systolic blood pressure (SBP) \>= 150 mmHg, despite appropriate therapy for at least 3 months
* 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
