Figure 2 Prevalence of reversible regional wall motion abnormality (RWMA) and reversible perfusion defects, with varying degrees of angiographic coronary stenosis by vascular territory. The percentage of patients with angiographic stenoses of 50% to 79% (mean and median values 70%) and 80% to 99% (mean and median values 90%) that show reversible RWMA (summed difference [perfusion] score for wall motion >2), compared with those that show reversible perfusion defects (summed difference [perfusion] score >2), are shown for specific vascular territories, defined by myocardial segments typically supplied by the following coronary arteries: anterior = left anterior descending, septal and diagonal; lateral = circumflex and obtuse marginal; and inferior = right and posterior descending.
