Possibilities of Cardiac Scintigraphy with 123I-Iodophen in Patients with Various Forms of Cardiomyopathies

Abstract

We explore the possibilities of cardiac scintigraphy with 123I-iodophen in patients with various forms of cardiomyopathy. In patients with ischemic cardiomyopathy, defects of metabolism correspond to the zones of postinfarction cardiosclerosis and uncoordinated defects typical for hybernation. In patients with dilated cardiomyopathy diffusion and heterogeneous character of impairment of coronary microcirculation and metabolism was predominantly identified. The distribution of 123I-iodophen in the LV myocardium has diffusion and uneven, mosaic character without strict compliance with the basin of the certain coronary artery. A distinctive feature of the non-coronary cardiomyopathy is the absence of mismatched defects of perfusion and metabolism.
