Figure 2 Histogram of myocardial perfusion in hearts from patients who exhibited steal in at least one segment. In these patients, as depicted, myocardial perfusion at rest in segments with and without steal was equivalent. However, after dipyridamole, segments with steal exhibited an absolute reduction in perfusion, whereas segments without steal vasodilated to similar levels as those observed in patients without steal. Open bars: segments with steal (n = 24); solid bars: segments without steal (n = 40).
