Brief Summary

In patients with a myocardial infarction (MI) treated medically alone, the objective of the PANTHEON trial is to evaluate if ticagrelor monotherapy reduces bleeding events, without an increase in patient-oriented ischemic events, compared with standard dual antiplatelet therapy (DAPT) with aspirin and ticagrelor for 12 months.

Eligibility Criteria

Inclusion criteria: * Age ≥18 years; * Hospitalized for type 1 MI, according to the 4th Universal Definition of MI; * Coronary angiogram performed; * Planned for medical management alone, without revascularization; * Willingness to participate and to attend study visits; * Expected life expectancy ≥12 months. Exclusion criteria: * Patients hospitalized for type 2-5 MI, or unstable angina, according to the 4th Universal Definition of MI; * Patients hospitalized for a STEMI with an acute thrombotic lesion of a major epicardial vessel; * Elevations in cardiac biomarkers (troponins or CK-MB) that is believed by the investigator not to be of ischemic origin (e.g. myocardial injury, myocarditis, Takotsubo syndrome, etc.); * Confirmed or suspected spontaneous coronary artery dissection; * Concomitant indication for chronic oral anticoagulant; * Concomitant non-coronary indication for dual antiplatelet therapy; * Use of any non-trial antiplatelet drug that needs to be continued based on the judgement of the treating physician; * Previous hospitalization for MI, PCI, or CABG within 12 months; * Known hypersensitivity, intolerance, or contra-indication to ASA or ticagrelor; * Unsuitability for either randomization treatment, based on the judgement of the treating physician
