Per the ADA 2017 guidelines, atherosclerotic CVD was defined as follows: acute coronary syndrome, history of myocardial infarction, stable or unstable angina, coronary or other arterial revascularization, stroke, transient ischemic attack, or peripheral arterial disease presumed to be of atherosclerotic origin
ACS acute coronary syndrome, PAD peripheral arterial disease, MI history of myocardial infarction, TIA transient ischemic attack
aRevascularization: coronary or other arterial revascularization
