Acute cardiovascular events including stent thrombosis are frequent after acute myocardial infarction
Drug interaction, problems of absorption or unstable hemodynamics could lead to a decrease in effectiveness of antithrombotic therapy
High platelet reactivity on aspirin and P2Y12i have never been studied in acute myocardial infarction
class="boldFont">What does this paper add?
HPR-aspirin is frequent at the acute phase of myocardial infarction (23%)
HPR-aspirin alone and HPR on both aspirin and P2Y12i are significantly associated with MACCE
The occurrence of HPR-aspirin decreases over time following the acute event
