STEMI
= ST-elevation myocardial infarction, NSTEMI = non ST-elevation myocardial
infarction, L = litre, TNI = troponin I, CK = creatine
kinase, ECG = electrocardiogram, AF = atrial fibrillation, VT/VF = ventricular
tachycardia or ventricular fibrillation, Heart block = Mobitz
II or complete heart block, LV Preserved = left ventricular systolic function
preserved (left ventricular ejection fraction > 50%), LV Mild = mild
reduction of left ventricular systolic function (left ventricular ejection
fraction > 40% - 50%), LV Moderate = moderate reduction of left ventricular
systolic function (left ventricular ejection fraction 35 - 40%), LV Severe =
severe reduction of left ventricular systolic function (left ventricular
ejection fraction < 35%), CABG = coronary artery bypass grafting.
