Figure 2 Short-axis slices from one representative patient during dipyridamole stress testing. There is a severe defect in the anterior and septal segments with placebo (arrows, upper panels) that partially reverses with pravastatin treatment (arrows, lower panels).

Figure 3 Polar map display and quantitative analysis of the SPECT study obtained in the same patient represented in Figure 2. The images were obtained during dipyridamole stress and at rest, after placebo (upper panel) and pravastatin treatment (lower panel). The percentage of perfusion defect is represented for each of three vascular territories (LAD = left anterior descending; RCA = right coronary artery; LCX = left circumflex) and for the total left ventricle.
