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.

Outcome Measures

Primary Outcome Measures :
  1. Number of Subjects Reaching the Composite Endpoint of Cardiovascular (CV) Death, Nonfatal Myocardial Infarction (MI), or Nonfatal Stroke [ Time Frame: Randomization up to 15 months ]
    The endpoint in this measure is a combination of CV death, nonfatal MI, or nonfatal stroke. The data is presented by the study population, which is represented as follows: 1) subjects who presented with unstable angina and non-ST-segment elevation myocardial infarction (UA/NSTEMI), 2) subjects who presented with ST segment elevation myocardial infarction (STEMI), and 3) all subjects with acute coronary syndromes (ACS) (i.e. all subjects with UA/NSTEMI or STEMI).


Secondary Outcome Measures :
  1. Number of Treated Subjects With Non-Coronary Artery Bypass Graft (CABG) Related Thrombolysis In Myocardial Infarction (TIMI) Study Group Major and Minor Bleeding Events [ Time Frame: First dose of study drug up to 15 months (while at risk) ]
    TIMI classification for major and minor bleeding in the subset of subjects who did not undergo a coronary artery bypass operation (CABG) were defined as follows: Major bleeding: any intracranial hemorrhage (ICH) OR any clinically overt bleeding (including bleeding evident on imaging studies) associated with a fall in hemoglobin (Hgb) of ≥5 grams/deciliter (gm/dL)from baseline. Minor Bleeding: any clinically overt bleeding associated with a fall in Hgb of ≥3 gm/dL but <5 gm/dL from baseline. Major bleeding events were further examined as events that were deemed life threatening and/or fatal.

  2. Number of Subjects Reaching the Composite Endpoint of Cardiovascular (CV) Death, Nonfatal Myocardial Infarction (MI), or Urgent Target Vessel Revascularization (UTVR) [ Time Frame: Randomization to 30 days; randomization to 90 days ]
    The endpoint in this measure is a combination of CV death, nonfatal MI, or UTVR. Results are reported for the All ACS subject population for the 30 and 90 day periods.

  3. Number of Subjects Reaching the Composite Endpoint of Cardiovascular (CV) Death, Nonfatal Myocardial Infarction (MI), or Nonfatal Stroke [ Time Frame: Randomization to 30 days; randomization to 90 days ]
    The endpoint in this measure is a combination of CV death, nonfatal MI, or nonfatal stroke. Results are reported for the All ACS population for the 30 and 90 day periods.

  4. Number of Subjects Reaching the Composite Endpoint of Cardiovascular (CV) Death, Nonfatal Myocardial Infarction (MI), Nonfatal Stroke, or Rehospitalization for Cardiac Ischemic Events [ Time Frame: Randomization up to 15 months ]
    The endpoint in this measure is a combination of CV death, nonfatal MI, nonfatal stroke, or rehospitalization for cardiac ischemic events. Results are reported for the All ACS population.

  5. Number of Subjects Reaching the Composite Endpoint of All-Cause Death, Nonfatal Myocardial Infarction (MI), or Nonfatal Stroke [ Time Frame: Randomization up to 15 months ]
    The endpoint in this measure is a combination of all-cause death, nonfatal MI, or nonfatal stroke. Results are reported for the All ACS population.
