Disturbances in cardiovascular neural regulation, influencing both disease course and
survival, progress as heart failure worsens. Heart failure due to left ventricular systolic …

Catecholamines are translocated across plasma membranes by transporters that belong to
two large families with mainly neuronal or extraneuronal locations. In mammals, neuronal …

Background. Iodine 123 metaiodobenzylguanidine (MIBG) imaging and heart rate variability
(HRV) analysis were compared in patients with an implantable cardioverter defibrillator …

Objectives: We hypothesized that some aspects of left ventricular assist device (LVAD)
reverse remodeling could be independent of hemodynamic factors and would primarily …

Cardiac autonomic innervation plays a key role in maintaining hemodynamic and
electrophysiologic harmony. Cardiac sympathetic function is adversely altered in many …

Objectives: The purpose of this study was to analyze the effects of left ventricular assist
devices (LVADs) on myocardial sympathetic innervation of the failing heart. Background …

Abstract Background 123 I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy is one
of only a few methods available for objective evaluation of cardiac sympathetic function at a …

Radionuclide cardiac imaging has potential to assess underlying molecular,
electrophysiologic, and pathophysiologic processes of cardiac disease. An area of current …

Background Carvedilol treatment reduces the mortality rate in patients with congestive heart
failure. It is not known whether carvedilol treatment is effective in heart failure patients with …

Heart failure (HF) is characterized by activation of the sympathetic cardiac nerves. The
condition of cardiac sympathetic nerves can be evaluated by 123 I …
