Study Description

Brief Summary:
Patients undergoing percutaneous coronary intervention with a residual high platelet reactivity despite oral clopidogrel are at increased risk of ischaemic complications. The strategies to overcome the issue consist of switch to a more potent antiplatelet medications including prasugrel or ticagrelor. Economic constrains of many countries still do not allow wide reimbursement of newer antiplatelet agents. Therefore a strategy to personalise treatment according to genotype and phenotype characteristics of the patient may provide an attractive solution combining high clinical efficacy with low budget impact.

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Genotyping Arm
Rapid genotyping to select optimal P2Y12-inhibitor for PCI.
 Device: Genotyping
Patients harboring CYP2C19 *2 alleles receive 60 mg prasugrel for PCI, while non-carriers receive 600 mg clopidogrel if not pretreated with clopidogrel.
Other Name: Spartan rapid genotyping device to screen CYP2C19 *2 carriage in patients in the Genotyping Arm.
Experimental: Phenotying Arm
The use of platelet function testing to select the optimal P2Y12-inhibitor for PCI.
 Device: Phenotyping
Patients having high on-treatment platelet reactivity (HPR: greater than 208 PRU) receive 60 mg prasugrel loading dose (LD), others continue clopidogrel for PCI.
Other Name: VerifyNow P2Y12 assay to test the response to clopidogrel.
No Intervention: Conventional Arm
Regular approach for performing elective PCI.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Prevalence of periprocedural myocardial injury within 24 h after PCI [ Time Frame: Within 24 hours after Percutaneous Coronary Intervention (PCI) ]
    Post-procedural troponin value increase exceeding the 99th percentile upper reference limit (URL) within 24 hours after PCI


Secondary Outcome Measures :
  1. Proportion of patients having periprocedural myocardial infarction (MI) [ Time Frame: Within 24 hours or PCI ]
    Periprocedural MI is defined as a CK-MB elevation greater than 3x of the upper limit of norm (ULN) within 24 hours of elective PCI.


Other Outcome Measures:
  1. Peak troponin elevation [ Time Frame: Within 24 hours of PCI ]
    The level of peak troponin-I elevation during 24 hours of elective PCI

  2. Proportion of patients with peri-procedural MI [ Time Frame: Within 24 hours of PCI ]
    The rate of peri-procedural MI defined as a peak troponin-I value greater than 5x the ULN within 24 hours.

  3. BARC type 3 and 5 bleeding [ Time Frame: Within 1 week of PCI ]
    BARC-defined type 3 (clinical, laboratory, and/or imaging evidence of bleeding, with healthcare provider responses) and type 5 (fatal) bleeds happening within 7 days of PCI.

  4. Death, MI, stent thrombosis (ST) or urgent repeat revascularization [ Time Frame: 30 days after PCI ]
    The rate of cardiac death, myocardial infarction, definite or probable stent thrombosis or urgent repeat revascularization within 30 days of elective PCI.
