Definition of the infarct and remote zone myocardium. a, In case the culprit coronary artery lesion was in the proximal left anterior descending coronary artery (LAD), the infarct zone was defined according to the 16-segment model of the left ventricle (LV) with the segments 1–2, 7–8 and 13–16 and the rest of the LV myocardium was defined as the remote zone. b, If the culprit lesion was found in mid or distal LAD, the infarct zone included segments 7–8 and 13–16 and the rest of LV myocardium was defined as the remote zone. LAD, left anterior descending; LCX, left circumflex; LM, left main
