Figure 3 Changes in LVEF by BCO (ordinate) were plotted against the minimal 123I-MIBG counts of the artery of interest in all lesions (abscissa). Six of seven patients with a substantial fall in LVEF ( 10%) had augmentation of the LF components, regardless of the conditions of cardiac sympathetic innervation. In contrast, in 16 patients with mild ischemia provoked by a fall in LVEF of <10%, the prevalence of augmentation of LF components was significantly less in lesions with cardiac denervation (minimal count of MIBG <52.2%) than in those without cardiac denervation. Solid squares = patients with augmentation of LF components; open circles = patients without augmentation of LF components. Abbreviations as in Figure 1.
