Enrollment: 5000
Study Start Date: August 2010
Study Completion Date: October 2013
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Aspirin
Aspirin monotherapy (stopping clopidogrel at 1 year after DES)
Drug: Aspirin monotherapy
stopping clopidogrel at 1 year after DES
Other Name: Aspirin monotherapy
Experimental: Aspirin,Clopidogrel
Aspirin,Clopidogrel Dual antiplatelet therapy (continue aspirin and clopidogrel 1year after DES)
Drug: Aspirin,Clopidogrel
continue aspirin and clopidogrel 1year after DES
Other Name: Aspirin,Clopidogrel Dual antiplatelet therapy

Detailed Description:

This is subsequent clinical trial of previously published pooled analysis of the REAL-LATE and the ZEST-LATE Trial, in which nonsignificant higher trend for increased rate of death (all-cause and cardiac), myocardial infarction, or stroke in the dual antiplatelet therapy group compared to the aspirin monotherapy group was noted.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • 1. Patients had undergone DES implantation at least 12 months before enrollment, had not had a MACE (death, MI, stroke, or repeat revascularization) or major bleeding, and were dual-therapy at the time of enrollment.
  • 2. Time for index PCI to randomization: 12-18 months

Exclusion Criteria:

  • Contraindications to the use of antiplatelet drugs (e.g., a concurrent bleeding diathesis or a history of major bleeding)
  • Concomitant vascular disease requiring long-term use of clopidogrel
  • Other established indications for clopidogrel therapy (e.g., a recent ACS).
  • Noncardiac coexisting conditions with a life expectancy < 1 year.
