The study sponsor, Prolocor, has developed an investigational test that is designed to guide individualized care in patients who have had a heart attack. Patients that have had a heart attack are at heightened risk of heart attack and stroke in the future. 

800 patients who have had a heart attack will be enrolled in the trial overall to determine whether the test can identify patients who are at a higher risk of heart attack or stroke in the future. 

Inclusions:

1. Male or female subjects ≥ 18 years of age hospitalized with confirmed type 1 MI (STEMI or NSTEMI), referred to as the index event (described in Appendix 1).
2. Must have ≥ 2 of the following risk factors:
a) Age ≥ 65
b) Multi-vessel coronary artery disease (MVD) defined as ≥2 vessels or left main with a stenosis ≥50%
c) Chronic kidney disease (CKD) defined as estimated glomerular filtration rate (GFR) ? 60 ml/min/1.73 m2
d) Diabetes mellitus (DM)
e) Prior MI

3. Must agree to participate in the study, to comply with all study procedures and follow-up contact
4. Signed the informed consent form

Exclusions:

1. Participation in another trial in which the subject is known to receive or could receive anticoagulant or antiplatelet treatment as part of the trial intervention.
2. Non-cardiovascular conditions that, in the judgment of the investigator, will limit survival to less than 2 years
