Inclusion criteria

Inclusion criteria: Patients aged 18 years or older are eligible for inclusion if all of the following criteria are met: - Clinical and electrocardiographical diagnosis of ST-elevation myocardial infarction - Successful primary percutaneous coronary intervention (according to the treating physician) of the infarct-related vessel with a modern drug-eluting stent Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 200 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 200

Exclusion criteria

Exclusion criteria: - Known allergy or contraindication for aspirin, ticagrelor or prasugrel. - Previous primary percutaneous coronary intervention or acute myocardial infarction less than 12 months ago - Previous cardiac surgery - Participation in another clinical study with an investigational product - Pregnancy and breast feeding - Concurrent use of oral anticoagulants - The periprocedural use of GPIIb/IIIa inhibitors - Planned surgical intervention within 12 months of primary percutaneous coronary intervention - Creatinine clearance <30 mL/min or dialysis - Primary percutaneous coronary intervention of stent thrombosis - Suboptimal stent result as judged by the interventional cardiologist - Contra-indications for cardiac magnetic resonance imaging or unable to undergo cardiac magnetic resonance imaging (only applicable for the cardiac magnetic resonance imaging subgroup population).

Design outcomes

Primary

MeasureTime frame
Main Objective: To assess the clinical safety of ticagrelor monotherapy directly after primary percutaneous coronary intervention for ST-elevation myocardial infarction with regards to thromboembolic outcomes: (Cardiovascular) death, myocardial infarction, stent thrombosis and ischemic stroke.;Secondary Objective: - To demonstrate the difference in infarct size and intramyocardial haemorrhage measured by cardiac magnetic resonance imaging in favour of ticagrelor monotherapy compared to ticagrelor + aspirin. - To compare (Bleeding Academic Research Consortium) BARC = 2 bleeding outcomes of ticagrelor monotherapy versus dual antiplatelet therapy directly after primary percutaneous coronary intervention for ST-elevation myocardial infarction - To compare all cause mortality in patients receiving ticagrelor monotherapy versus dual antiplatelet therapy. - To compare platelet reactivity between ticagrelor monotherapy and ticagrelor + aspirin. ;Primary end point(s): Composite of major adverse cardiac and cerebral events (MACCE), consisting of: - Myocardial infarction - Stent thrombosis - Ischemic stroke - Mortality (both all-cause mortality and cardiovascular mortality will be taken into account separately. - MACCE including all-cause mortality - Bleeding complications BARC = 2 - All-cause mortality ;Timepoint(s) of evaluation of this end point: 1 month, 3 months and 12 months after primary percutanous coronary intervention

Secondary

MeasureTime frame
Secondary end point(s): Size of intramyocardial haemorrhage and infarct determined by cardiac magnetic resonance imaging;Timepoint(s) of evaluation of this end point: Between 5-8 days post primary percutaneous coronary intervention
