摘要

Major adverse cardiovascular events after percutaneous coronary intervention (PCI) are driven in large part by platelet activation and aggregation. Clopidogrel, a platelet P2Y12 adenosine diphosphate (ADP)-receptor inhibitor, reduces such events when combined with aspirin after acute coronary syndrome and PCI, albeit with more bleeding. However, the antiplatelet effect of clopidogrel varies quite substantially between individuals. Although the goal of antiplatelet therapy is obviously to inhibit platelet activity, the clinical implications of response variability have led to much debate, particularly within the context of recent, negative trials of platelet function testing to guide antiplatelet therapy after PCI. In The Lancet, Gregg Stone and colleagues6 report the results of the ADAPT-DES registry, the largest observational study to date on testing of platelet function after PCI. Although many questions remain, this seminal study moves the debate from whether testing of platelet function is biologically relevant to how and when it should be used clinically.
