Outcomes after acute myocardial infarction (MI) can be improved by lifestyle changes; control of cardiovascular risk factors; and treatment with secondary preventive medications, such as aspirin, P2Y12-inhibitors, statins, beta blockers, angiotensin-converting enzyme inhibitors (ACEIs), and/or angiotensin-receptor blockers (ARBs), all of which are recommended in international guidelines [1–3]. Here, P2RY12 is linked to myocardial infarction.
