Note: CABG = coronary artery bypass graft, CPR = cardiopulmonary resuscitation, ECG, electrocardiogram, eGFR = estimated glomerular filtration rate, EMS= emergency medical services, LVEF = left ventricular ejection fraction, MI = myocardial infarction, PCI = percutaneous coronary intervention, STEMI = ST-segment elevation myocardial infarction, TIA = transient ischemic attack, TIMI = thrombolysis in myocardial infarction. *Unless otherwise indicated. †Number in parentheses is the number of patients with available values for that variable.
