Figure 5.

Phase analysis for a patient with balanced 3-vessel disease (LAD stenosis 70%, LCX stenosis 80%, RCA stenosis 70%, respectively). (A) The perfusion polar map revealed only mild grade of perfusion abnormality with partial reversibility in apex and inferior wall. (B) Phase polar map revealed remarkable deterioration in global synchrony from rest to stress, with phase SD and bandwidth of 18° and 65° at rest, and 31° and 85° at stress, respectively. LAD, left anterior descending artery; LCX, left circumflex artery; RCA, right coronary artery.
