Figure 3 Relationship between the presence of abnormal flow (CTFC 28) in nonculprit arteries and a wall motion abnormality within the distribution of the nonculprit artery. Patients with abnormal nonculprit artery flow had a greater frequency of regional wall motion abnormalities within the distribution of the nonculprit artery (p < 0.001). When the analysis was restricted to patients without a prior MI, similar findings were observed (p = 0.038).
