6.01.56 Myocardial Sympathetic Innervation Imaging in Patients with Heart Failure

Influence of diabetes mellitus on prognostic utility of imaging of myocardial sympathetic innervation in heart failure patients.

BACKGROUND Patients with diabetes mellitus have accelerated progression of heart failure and often have impaired cardiac sympathetic innervation. The present study examines the implications for heart failure progression of cardiac sympathetic denervation, assessed by I-123 metaiodobenzylguanidine imaging, in diabetic compared with nondiabetic subjects. METHODS AND RESULTS We evaluated 343 dia...

False adrenergic transmitters and positron emission tomographic imaging of myocardial sympathetic innervation.

D uring the past 50 years, isotopic tracer methods have become standard techniques for analysis of dynamic biochemical and physiological processes in vitro and in vivo. When liquid scintillation spectrometry was introduced approximately 35 years ago, assay of /3 emitting isotopes was simplified. This resulted in widespread application of isotopic methods to study metabolism and disposition of p...
