Figure 3 Myocardial blood flow in the subendocardial (upper panel) and subepicardial (lower panel) regions of the occluded area for the different groups (control group represented by open bars; fully supported group = darker shaded bars; group supported in reperfusion only = lighter shaded bars; and group with partial support during reperfusion = solid bars). During occlusion, there was almost no flow in either of the groups. At reperfusion, the fully supported group was the only group to show normal myocardial perfusion. BS = baseline; occl = during coronary occlusion; reperf = reperfusion. *Significant difference (Student t test) compared with the baseline value. ^#Significant difference (Student t test) compared with the control group.
