Figure 4 Time course of changes in the myocardial blood flow within the risk area at baseline, occlusion, and after coronary reperfusion for the control (n = 8) and glycoprotein IIb/IIIa inhibitor (GPI) (n = 8) groups. *p < 0.05 versus control group at each stage. The data during occlusion and reperfusion are expressed as the mean percentage of baseline ± SD. R-30, R-60, R-90, and R-180 = reperfusion for 30, 60, 90, and 180 min, respectively.
