Clinical Trial Summary

APERITIF is a prospective randomized open-label, blinded end-point (PROBE) trial, nested in the ongoing the "FRENCHIE" registry, a French multicenter prospective observational study granted by "ANR-RHU Grand Emprunt", in which all consecutive patients admitted within 48 hours after symptom onset in a cardiac Intensive Care Unit (ICU) for an acute myocardial infarction (AMI) are included (NCT04050956). Among them, eligible Patients for "APERITIF" will be randomized into two groups: Dual Anti-Platelet Therapy (DAPT) alone or DAPT plus rivaroxaban 2.5mg twice daily for 4 weeks, prescribed as soon as possible after admission and completion of the initial percutaneous coronary intervention/angiography procedure.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Rate of thrombus between the two arms	The main objective of this randomized trial is to determine whether, in anterior AMI patients (e.g., large necrosis area), the use of rivaroxaban 2.5mg twice daily in addition to DAPT (dual antiplatelet therapy) will reduce LV thrombus formation, compared with the use of DAPT alone (current practice).; The primary endpoint is the presence of Left Ventricular (LV) thrombus at 1-month, as detected by the validated delayed enhancement (Cardiovascular Magnetic Resonance) CMR method	1 month
Secondary	Description of the thrombus	LV thrombus dimension (greatest diameter)	1 month
Secondary	Rate of bleeding events	Rate of bleeding events using the Thrombolysis in Myocardial Infarction (TIMI) and the Bleeding Academic Research Consortium (BARC) criteria at 1 month (investigator-reported),	1 month
Secondary	Rate of major adverse cardiac events (MACE) at 1 month	Rate of major adverse cardiac events (MACE) defined as a composite of death, non-fatal MI or stroke at 1 month	1 month
Secondary	Rate of major adverse cardiac events (MACE) at 1 year	Rate of major adverse cardiac events (MACE) defined as a composite of death, non-fatal MI or stroke at 1-year	1 year
Secondary	Rate of antithrombotic using	Antithrombotic drugs used in the patients with confirmed LV thrombus on CMR between 1 month and 1 year	1 year
