The objective of this study is to compare reduced-dose prasugrel and standard dose clopidogrel in patients older than 74 years with ACS, including non-ST-elevation (NSTEACS) and ST-elevation (STEMI) patients, undergoing early PCI. The primary endpoint of the trial will be the one-year composite of (all-cause)death, myocardial infarction, stroke and re-hospitalization due to cardiovascular reasons or bleeding.

Primary Outcome Measures:
  • The composite of all-cause mortality, myocardial infarction (MI), disabling stroke and re-hospitalization for cardiovascular causes or bleeding within one year [ Time Frame: 1 year ]

Secondary Outcome Measures:
  • The composite of burden of recurrent cardiovascular (CV) events, CV mortality, all-cause mortality and MI, major bleeding, any stroke, total number of days spent in hospital. [ Time Frame: 1 year ]

    definition of major bleeding:

    - Bleeding Academic Research Consortium (BARC) type 2 or 3 bleeding within 1 year (for bleedings occurring during index or subsequent hospitalizations)

    · BARC type IV bleeding within 1 year

Ages Eligible for Study:   75 Years and older   (Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

- Patients >74 years of age hospitalized for an ACS, with or without STE, with an onset of symptoms during the previous 72 hours, and candidates to an early PCI.

  • STEMI patients may be randomized upon first diagnosis, provided they do not meet any exclusion criteria. STEMI patients should not exceed 50 percent of the global population of the study
  • Eligible NSTEACS patients may be randomized after coronary angiography. To be eligible, NSTEACS patients must have at least one of the following characteristics:

    • elevated troponin levels;
    • diabetes mellitus;
    • prior MI;
    • at least one new ischemic episode while on standard treatment during the index hospitalization;
    • ACS due to stent thrombosis.

Exclusion Criteria:

  • History of stroke or transient ischemic attack (TIA)
  • Gastrointestinal or genitourinary bleeding of clinical significance within 6 weeks prior to randomization.
  • Hemoglobin level on admission <10 g/dl, unless this is considered to be secondary to renal dysfunction or known myelodysplasia.
  • Secondary causes of acute myocardial ischemia.
  • Known current platelet count < 90,000 cells/mL.
  • Ongoing oral anticoagulant treatment or an INR known to be >1.5 at the time of screening.
  • Concomitant severe obstructive lung disease, malignancy or neurologic deficit limiting follow-up or adherence to the study protocol.
  • Participation in any phase of another clinical research study involving the evaluation of another investigational drug or device within 30 days prior to randomization
  • Inability to give at least verbal informed consent to the study.
  • Contraindications to the use of clopidogrel or prasugrel as per package leaflet.
