Stroke Clinical Trials

• Age 18 years or above at the time of signing the informed consent.

• Hospitalisation for acute myocardial infarction with evidence of type 1 myocardial infarction (MI) by invasive angiography performed at site with percutaneous coronary intervention (PCI) capabilities.

• ST-segment elevation myocardial infarction (STEMI) with all the following: a) Relevant onset of symptoms suggestive of cardiac ischaemia within 12 hours before hospitalisation, at the investigator's discretion.

• b) Electrocardiogram (ECG)-changes (in the absence of left ventricular hypertrophy or left bundle branch block): ST-segment elevation at the J point in at least two contiguous leads greater than or equal 0.25 (millivolt) mV in men less than 40 years, greater than or equal 0.2 mV in men greater than or equal 40 years, or greater than or equal 0.15 mV in women in leads V2-V3; and/or greater than or equal 0.1 mV in all other leads.

⁃ OR

• Non-ST-segment myocardial infarction with all the following: a) Relevant onset of symptoms suggestive of cardiac ischaemia within 24 hours before hospitalisation, at the investigator's discretion. b) Rise and/or fall in car-diac troponin I or T with at least one value above the 99th percentile upper reference limit.

• Possibility for both randomisation and administration of the loading dose of study intervention as early as possible after invasive procedure, and latest within 36 hours of hospitalisation (time 0) for STEMI, and latest within 72 hours of hospitalisation (time 0) for NSTEMI.

• Presence of at least one of the following criteria confirmed based on the participant's medical records and/or medical history interview: a) Any prior MI. b) Prior coronary revascularisation. c) Diabetes mellitus treated with ongoing glucose-lowering agent(s). d)Known chronic kidney disease (CKD) (estimated glomerular filtration rate (eGFR) greater than or equal to 15 and less than 60 milliliter per minute per 1.73 square meter (mL/min/1.73 m\^2). e) Prior ischaemic stroke. f) Known carotid disease or peripheral artery disease in the lower extremities. g) Multivessel coronary artery disease (current/prior). h) For STEMI patients only: anterior MI at index acute myocardial infarction (AMI)
