The autonomic phenotype of congestive cardiac failure is characterised by high sympathetic
drive and impaired vagal tone, which are independent predictors of mortality. We …

Neumpeptidc Y (NPYJ is a 36 amino acid prptide present in the brain, the adrenal medulla
and peripheral sympathetic nerves. The localization and mode of release of NPY led to the …

This study examined the effects of low doses of intravenous clonidine on regional and global
sympathetic nervous system activity in heart failure. In heart failure, adrenoceptor-blocking …

The sympathetic nervous system plays an important role in the occurrence of ventricular
tachycardia (VT). Many patients, however, experience VT despite maximal doses of beta …

The co-transmitter neuropeptide Y (NPY), released during prolonged cardiac sympathetic
nerve stimulation, can attenuate vagal-induced bradycardia. We tested the hypothesis that …

β3‐Adrenoceptor agonists have proven useful in the treatment of overactive bladder
syndrome, but it is not known whether their efficacy during chronic administration may be …

Objective: To assess urinary 6-sulfatoxymelatonin excretion in patients admitted to the
hospital because of congestive heart failure (CHF). Methods: Urinary 6-sulfatoxymelatonin …

Objectives: The present investigation was designed to determine the best endogenous
plasma marker of early congestive heart failure (CHF). Methods: Forty volunteers with mild …

OBJECTIVES The aim of this study was to investigate the role of peripheral presynaptic
alpha-2 adrenergic receptors in modulating norepinephrine (NE) release in congestive heart …

Neuropeptide Y (NPY) is a co-transmitter of the sympathetic nervous system including the
renal nerves. The kidney expresses NPY receptors, which can also be activated by peptide …
