The relationship among neuropeptide Y (NPY), catecholamines and haemodynamics was
assessed both at baseline and during inotropic intervention in patients with congestive heart …

Neuropeptide Y (NPY) exerts potent vasoconstrictor activity and is coreleased with
noradrenaline from sympathetic nerves, mainly on a high degree of activation. It may …

Neuropeptide-Y (NPY) is a sympathetic cotransmitter, which causes vasoconstriction,
decreases coronary blood flow and decreases cardiac output. Circulating immunoreactive …

The direct and reflex-mediated components of the cardiovascular response to administration
of neuropeptide Y (NPY) in intact conscious rabbits were determined by studies with cardiac …

Plasma neuropeptide Y (NPY) was measured by radioimmunoassay in 43 patients with
congestive heart failure (CHF) and 20 healthy control subjects. The results showed that …

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 …

Neuropeptide Y (NPY) is a recently isolated vasoactive peptide, which is present, together
with catecholamines, in sympathetic nerves and in the adrenal medulla. In the present study …

Neuropeptide Y (NPY) is released from sympathetic neurons and exerts short-term (acute)
effects on prejunctional nerve terminals and postjunctional cardiac ion channels. However …

The purpose of this study was to examine the sympathetic-parasympathetic interactions on
heart rate through release of neuropeptide Y (NPY) and its action on prejunctional NPY Y 2 …
