    Abstract:
    201TlCl (Tl), 123I-beta-methyl-p-iodophenyl pentadecanoic acid (BMIPP) and 123I-metaiodobenzylguanidine (MIBG) images were applied before and after PTCA to a patient with acute coronary syndrome who had repeated ischemic attacks on light effort. A decreased tracer uptake was noted at the mid and apical anteroseptal regions in each image before PTCA. MIBG uptake was most decreased and Tl uptake was least decreased, but Tl uptake at exercise decreased as severely as MIBG uptake at rest. After PTCA an uptake was improved in each image. Both before and after PTCA, the area with decreased BMIPP uptake corresponded to the region with deteriorated wall motion obtained by echocardiography. It was suspected that the decreased MIBG uptake correlates with "area at risk" and that the decreased BMIPP uptake correlates with abnormal wall motion. Taken together those findings, it was indicated that an application of these cardiac scintigraphy is useful for the evaluation of comprehending metabolic abnormality and recovering process of ischemic myocardium.
