Inclusion criteria

Inclusion criteria: - Participants must have an index event that meets all 3 of the following criteria within 7 days prior to randomization: a) clinical syndrome consistent with spontaneous cardiac ischemia, b) diagnosis of acute coronary syndrome (ACS) (that is, ST-elevation myocardial infarction [STEMI], non-STEMI, or unstable angina [UA]), c) cardiac biomarker elevation (example, troponin I, troponin T, creatine kinase-MB [CK-MB]) above the upper limit of normal as determined by the local laboratory - Participants must have at least 2 of the following risk factors:a) age 65 or older, b) diabetes mellitus, c) history of a prior myocardial infarction (MI) (other than index ACS event), d) multivessel coronary artery disease (CAD), e) history of coronary artery bypass graft (CABG) surgery prior to index ACS event, f) history of peripheral artery disease (PAD) or cerebrovascular disease (example, carotid atherosclerosis, intracranial artery stenosis, g) conservative management (that is, no percutaneous intervention [PCI] or CABG after index ACS event), h) Any one or more of the following high-risk angiographic features i) total stent length of greater than (>) 30 millimeters (mm), ii) thrombotic target lesion, iii) bifurcation lesion treated with more than one stent, iv) calcified target lesion treated with atherectomy, v) treatment of obstructive left main or proximal left anterior descending artery for index ACS (or clinical diagnosis of an anterior STEMI) - All female participants of childbearing potential must have a negative highly sensitive serum beta-human chorionic gonadotropin (hCG) or urine test at screening - A female participant must not be pregnant, breastfeeding, or planning to become pregnant until 4 days (5 half-lives) after the last dose of study intervention

Exclusion criteria

Exclusion criteria: - MI secondary to ischemia due to either increased oxygen demand or decreased supply (Type 2 MI) or periprocedural MI as the index ACS event - Planned CABG or staged PCI after randomization - Any condition that requires chronic anticoagulation at the discretion of the investigator and/or local guidelines - Conditions with a significant increased risk of bleeding (example, clinically significant bleeding within previous 3 months, known bleeding diathesis, et cetera)

Design outcomes

Primary

MeasureTime frame
Time to First Occurrence of Major Adverse Cardiovascular Event (MACE) : Up to 3 years 6 months : Time to first occurrence of any component of MACE will be reported. MACE is a composite of cardiovascular (CV) death, myocardial infarction (MI), and ischemic stroke.

Secondary

MeasureTime frame
Time to the First Occurrence of Major Adverse Vascular Event (MAVE) : Up to 3 years 6 months : Time to first occurrence of any component of MAVE will be reported. MAVE is a composite of CV death, MI, ischemic stroke, major adverse limb event (MALE), and symptomatic venous thromboembolism (VTE). Time to the First Occurrence of Composite of All-cause Mortality (ACM), Myocardial Infarction (MI) and Ischemic Stroke : Up to 3 years 6 months : Time to the first occurrence of composite of ACM, MI and ischemic stroke will be reported. Time to Cardiovascular (CV) Death : Up to 3 years 6 months : Time to CV death will be reported. Time to All-cause Mortality (ACM) : Up to 3 years 6 months : Time to ACM will reported. ACM will be categorized into CV death, non-CV death, and death due to unknown cause.
