Diagnostic Test: Assessment of platelet reactivity
Diagnostic Test: Troponin measurement
Registration Number
NCT05332262

University of Florida
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.

Detailed Description

Antiplatelet therapy with aspirin and a P2Y12 inhibitor is the cornerstone of treatment for patients undergoing percutaneous coronary intervention (PCI). Clopidogrel is the recommended P2Y12 inhibitor in patients with stable coronary artery disease (CAD) undergoing elective PCI. However, clopidogrel effects are subject to variability and 30-40% of patients have high platelet reactivity (HPR), which translates into higher rates of thrombotic complications. 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 investigators recently developed a precision medicine tool integrating clinical and genetic factors called ABCD-GENE able to identify HPR status. This score helps characterize patients at risk for peri-PCI thrombotic complications, who can thus potentially benefit from changes in antiplatelet treatment regimen. However, the ABCD-GENE score was generated through retrospective assessments, thus warranting prospective validation. The high frequency of elective PCI procedures and the prevalence with which myocardial infarction/myocardial injury occurs underscore the need for tools that can better identify patients at risk so that therapeutic measures can be implemented to improve their prognosis. 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.
