Brief Summary

Despite the relative safety of PCI with new generation stents, peri-PCI thrombotic complications, including myocardial infarction and myocardial injury, are common in elective PCI, occurring in up to 30% of patients. Importantly, these events are associated with poor prognosis. The risk of peri-PCI myocardial infarction/myocardial injury has been in part attributed to HPR. The aim of this study is to prospectively validate the accuracy of the ABCD-GENE score in identifying stable CAD patients undergoing elective PCI treated with standard of care clopidogrel who are at risk of peri-PCI myocardial infarction/myocardial injury. This investigation will be a prospective cohort study conducted in a population of patients (n=500) with stable CAD undergoing elective PCI treated with standard of care clopidogrel. By integrating genetic data with clinical variables, patients will be stratified into 2 cohorts based on their ABCD-GENE score (using a cut-off of 10). Assessments to define HPR status and myocardial infarction/myocardial injury will be performed post-PCI.

Outcome Measures

Primary Outcomes (1)

  • Peri-PCI myocardial infarction or myocardial injury

    The primary endpoint of the study will be rate of peri-PCI myocardial infarction or myocardial injury, which will be compared between the high ABCD-GENE score cohort and the low ABCD-GENE score cohort.

    24 hours

Study Arms (2)

High ABCD-GENE score (≥10)

All patients in this cohort will have an ABCD-GENE score ≥10 and will be receiving clopidogrel following PCI as per standard of care. The ABCD-GENE score encompasses a total of 5 variables: 4 clinical (age, body mass index, chronic kidney disease status, and diabetes mellitus) and 1 genetic (CYP2C19 LOF).

Diagnostic Test: Assessment of platelet reactivityDiagnostic Test: Troponin measurement

Low ABCD-GENE score (<10)

All patients in this cohort will have an ABCD-GENE score \<10 and will be receiving clopidogrel following PCI as per standard of care. The ABCD-GENE score encompasses a total of 5 variables: 4 clinical (age, body mass index, chronic kidney disease status, and diabetes mellitus) and 1 genetic (CYP2C19 LOF).

Diagnostic Test: Assessment of platelet reactivityDiagnostic Test: Troponin measurement

Interventions

Assessment of platelet reactivity and HPR status will be performed post-PCI. Platelet reactivity will be measured by VerifyNow P2Y12 and HPR status will be defined using a cut-off value of platelet reactivity units (PRU)\>208.

High ABCD-GENE score (≥10)Low ABCD-GENE score (<10)
Troponin measurementDIAGNOSTIC_TEST

Measurement of high sensitivity troponin for the assessment for the presence of myocardial infarction/myocardial injury will be performed post-PCI.

Sampling MethodProbability Sample
Study Population

All-comers population of troponin-negative CAD patients undergoing elective PCI as part of their standard of care at the Division of Cardiology of University of Florida Health, Jacksonville, Florida. Genotyping will be performed as per standard of care in the UF Health Pathology lab.

You may qualify if:

  • Stable CAD undergoing elective PCI;
  • Male or females, Age ≥ 18 years old;
  • Troponin negative before PCI\*;
  • Background of aspirin therapy;
  • If troponin is unknown before coronary angiography and no clinical signs of acute coronary syndrome is present, a troponin will not be collected as this is line with standard practice.

You may not qualify if:

  • Current presentation with myocardial infarction;
  • On treatment with prasugrel or ticagrelor;
  • Documented hypersensitivity to clopidogrel;
  • Use of an intravenous antiplatelet therapy (i.e., cangrelor or GPI) during PCI;
  • Unable to provide written informed consent.
