The purpose of this study is to determine the efficacy and safety of a routine individualized antiplatelet therapy after coronary stent implantation by evaluating "on-treatment" platelet reactivity with Multiple Electrode Aggregometry (MEA, Multiplate® Analyzer).

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment

Primary Outcome Measures:
  • Definite Stent Thrombosis [ Time Frame: 30 days ]
    The angiographic or pathological confirmation of stent thrombosis is called "definite stent thrombosis"

  • Any Bleeding Event [ Time Frame: 30days ]

    Bleeding classified by the TIMI hemorrhage classification scheme:

    Minor: any clinically overt sign of hemorrhage (including imaging) that is associated with a hemoglobin drop of 3 to < 5 g/dL

    Major: (1) if it is intracranial, or (2) clinically significant overt signs of hemorrhage associated with a drop inhemoglobin of > 5 g/dL

Secondary Outcome Measures:
  • Probable Stent Thrombosis [ Time Frame: 30days ]

    Probable stent thrombosis is considered to have occurred in case of

    1. any unexplained death within the first 30 days.
    2. any MI that is related to documented acute ischemia in the territory of the implanted stent without angiographic confirmation of stent thrombosis and in the absence of any other obvious cause, irrespective of the time after the index procedure

Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: standard therapy
standard dual antiplatelet therapy after PCI for all patient populations (stable CVD and ACS)
Drug: Clopidogrel
clopidogrel 75mg od for 12 month
Other Name: Plavix
Experimental: individualized therapy
dual antiplatelet therapy modified according to clopidogrel on-treatment platelet reactivity measured by Multiplate Analyzer
Drug: prasugrel or ticagrelor
prasugrel 10mg od for 12 month ticagrelor 90mg td for 12 month
Other Names:
  • Efient
  • Brilique

Detailed Description:
Depending on the clinical presentation patients are treated according to standard operating procedures in our department. The earliest, 12 hours after an initial clopidogrel-loading dose (600mg)"on-treatment" platelet reactivity will be determined by Multiple Electrode Aggregometry (MEA, Multiplate® Analyzer), a point of care assay. In case of high residual platelet reactivity (i.e. ≥ 50U), patients are switched according to a therapeutic algorithm to either prasugrel (Efient®), or in case of contraindication (i.e. stroke) to ticagrelor (Brilique®), or in case of contraindication (intracranial hemorrhage) reloaded with clopidogrel.
