Figure 1 Plots of Individual Values of ST-Segment Shift on the IC-ECG During the First and Second Inflation in the 2 Groups of Patients

In gin-treated patients (left), ST-segment changes during the second inflation were significantly greater than those during the first inflation (p = 0.03). Conversely, in placebo-treated patients (right), ST-segment changes during the second inflation were significantly less than those during the first inflation (p = 0.005). IC-ECG = intracoronary electrocardiogram.
