Brief Summary:
This is a randomized, prospective, open label study to determine the cost-effectiveness of genotype-guided antiplatelet therapy. Patients undergoing percutaneous intervention (PCI) with stent implantation, will be randomized either to genotype guided dosing of antiplatelet therapy or usual care. The study utilizes a novel genotyping device, SpartanRx, to determine CYP2C19 genotypes from a buccal swab sample with 1 hour turnaround time.

Official Title: Assessment of Prospective CYP2C19 Genotype Guided Dosing of Anti-Platelet Therapy in Percutaneous Coronary Intervention (ADAPT)
Actual Study Start Date : November 2014

Actual Study Completion Date : August 2017

Arm Intervention/treatment
Experimental: CYP2C19 Genotype guided
Prospective CYP2C19 genotyping to decide antiplatelet therapy.
Genetic: CYP2C19 genotyping
The study utilizes a genotyping device, SpartanRx™ (Spartan Bioscience, Ottawa, Canada) that provides identification of a patient's CYP2C19 *2, *3, and *17 genotypes determined from genomic DNA from a buccal swab sample with 1 hour turnaround time
Other Name: SpartanRx

No Intervention: Control group
Antiplatelet therapy will be decided based on usual care

Primary Outcome Measures :
  1. The Number (Percentage) of Participants Receiving Prasugrel/Ticagrelor [ Time Frame: for up to 7 days after PCI ]
    The number (percentage) of participants receiving prasugrel/ticagrelor in each randomized arm

Secondary Outcome Measures :
  1. Number of Participants With Drug Orders in Agreement With the Genotype-guided Recommendations [ Time Frame: for up to 7 days after PCI ]
    Agreement to suggested treatment recommendations based on genotype. The agreement rate was defined as the number of participants in genotyped group with loss of function variants that received prasugrel or ticagrelor + the number of participants without these variants that received clopidogrel divided by the total number in this group.

  2. Number of Participants With Major Cardiac Events [ Time Frame: 1 year ]
    major cardiac events defined as occurrence of first myocardial infarction, ischemic stroke, cardiovascular death, stent thrombosis, or need for urgent revascularization

  3. Number of Participants With Bleeding Events [ Time Frame: 1 year ]

    major bleeding events defined by the Bleeding Academic Research Consortium (BARC) type 3 or 5.

    Type 3= Overt bleeding requiring: blood transfusion, surgical intervention or intravenous vasoactive agents; cardiac tamponade; intracranial hemorrhage; intraocular bleeding.

    Type 5= fatal bleeding
