Despite the use of potent P2Y12 inhibitor such as ticagrelor, half of the patients presented high platelet reactivity (HPR) at the time of primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI). HPR has been associated with impaired myocardial reperfusion. Myocardial reperfusion, assessed using myocardial blush grade, is a strong prognostic factor associated with infarct size and mortality. Antiplatelet therapy intensification using a potent and immediate P2Y12 inhibitor such as Cangrelor according a point-of-care platelet function test has not been studied in the acute phase of STEMI.~This study aims to evaluate the impact on myocardial reperfusion and residual thrombotic burden of adding Cangrelor to ticagrelor in primary PCI patients with high on ticagrelor platelet reactivity compared to standard of care with ticagrelor alone.
