Figure 2 This graph displays the changes over time of risk area/control area ratios of videointensity obtained from MCE and RBF in this study. Values are reported at baseline (BSL), during LAD occlusion (OCC), and at 5, 30, 90, and 180 min of reperfusion (RP). Both MCE and RBF ratios follow the same trend and their values are identical at each time point. Both parameters decreased significantly during coronary occlusion and increased over baseline at 5 min of reperfusion (*p < 0.0001 vs. baseline). At 30 min of reperfusion, both MCE and RBF ratios returned to baseline values and then progressively decreased at 90 and 180 min of reperfusion to a level lower than baseline (*p < 0.0001 vs. baseline for RBF).
