Differential prognostic impact of high on-treatment platelet reactivity among patients with acute coronary syndromes versus stable coronary artery disease undergoing percutaneous coronary intervention

There was a substantial interaction between platelet reactivity on clopidogrel and clinical presentations on cardiovascular events after PCI. High on-treatment platelet reactivity was significantly associated with higher risks of cardiovascular events in ACS patients, whereas this association was absent in stable CAD patients.
