Figure 2 Schematic definition of circumferential segments at the basal level (top), mid-ventricular level (middle) and apical level (bottom). The perfusion territory of the LAD was considered to be at the basal level in segments 10 to 3, at the mid level in segments 9 to 3 and at the apical level in segments 9 to 4. The infarct-related area is indicated by the dashed segments, the adjacent area by the solid segments and the remote area by the open segments. LAD = left anterior descending coronary artery.
