  Purpose

The purpose of this study is to assess the the 1-year rates of ischemic and bleeding complications in patients whose dual antiplatelet therapy regimen post-PCI has been determined with the use of a clinical algorithm that includes both clinical risks and platelet reactivity while on chronic clopidogrel therapy.

Primary Outcome Measures:
  • MACE [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
    Major adverse cardiac events (all-cause death, myocardial infarction and stent thrombosis)


Secondary Outcome Measures:
  • Rates of major bleeding [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
    The rates of major bleeding in patients treated with a thienopyridine based on the clinical algorithm.


Estimated Enrollment: 1000
Study Start Date: March 2012
Estimated Study Completion Date: February 2014
Estimated Primary Completion Date: February 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts
SA + 5mg prasugrel
Prasugrel 5 mg group: Patients with Intermediate or high bleeding risks and PRU ≥ 230 are Prescribed 5mg of prasugrel daily along with aspirin.
ASA + 10 mg prasugrel
Prasugrel 10 mg group: Patients with Low bleeding risk and high ischemia risk and PRU ≥ 230 are prescribed 10 mg of prasugrel daily along with aspirin.
ASA + 75 mg clopidogrel daily
Clopidogrel 75 mg group (control): PRU ≤ 230; high bleeding risk or high ischemic risk; patients with active malignancy, age >75; Wt< 60kg with previous CVA or TA are prescribed 75 mg of clopidogrel daily along with aspirin.

Detailed Description:

Prospective multicenter registry. Patients already on chronic dual antiplatelet therapy with aspirin and clopidogrel will be assessed for (1) clinical risks factors for future bleeding and ischemic complications, and (2) on-treatment platelet reactivity as measured by the VerifyNow P2Y12 assay (Accumetrics, Inc., San Diego, CA, USA). These will be considered by utilization of a clinical algorithm to determine the dual antiplatelet regimen post-PCI (aspirin in combination with 1. clopidogrel, 2. prasugrel 5mg daily, or 3. prasugrel 10mg daily).

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Subjects in any of the participating sites who are on chronic clopidogrel treatment and return for PCI will be considered for this study.

Criteria

Inclusion Criteria:

  • The subject has provided informed written.
  • The subject must be ≥ 18 years of age (or minimum age as required by local regulations) at the time of enrollment.
  • Patient is established on chronic clopidogrel therapy when he/she returns for PCI, and the components of DAPT are determined by the clinical decision algorithm as local standard of care.
  • The subject is willing and able to cooperate with the study procedures and required follow-ups.

Exclusion Criteria:
