Platelet Aggregation During the Shift From Clopidogrel to Ticagrelor

Patients allocated in the two study arms will receive the same anti platelet treatment, except for the administration of the loading dose, which will be only administered to patients allocated in Group 2

"Patients allocated in the two study arms will receive the same anti platelet treatment, except for the administration of the loading dose, which will be only administered to patients allocated in Group 2.~In other words, patients randomized to this group (group 1) will not receive a loading dose of ticagrelor during the passage from clopidogrel to ticagrelor."
