Heart failure (HF) is a complex clinical syndrome characterized by the activation of at least
several neurohumoral pathways that have a common role in maintaining cardiac output and …

Neuropeptide Y (NPY) is an abundant sympathetic co-transmitter, widely found in the central

Objectives. The aim of this study was to characterize cardiac sympathetic nervous function in
patients with severe heart failure and to investigate the influence of the cause of heart …

Through the past decade of research, the pathogenic mechanisms underlying metabolic
syndrome have been suggested to involve not only the peripheral tissues, but also central …

The two branches of the autonomic nervous system (ANS), adrenergic and cholinergic, exert
a multitude of effects on the human myocardium thanks to the activation of distinct G protein …

We conducted this study in an effort to characterize and understand vagal abnormalities in
heart failure patients whose sympathetic activity is known. We measured sympathetic …

Hypertension is an important risk factor for cardiovascular morbidity and mortality and for
events such as myocardial infarction, stroke, heart failure and chronic kidney disease and is …

Purpose Cardiac autonomic dysfunction is one of the main pillars of cardiovascular

Neuropeptide Y coexists with norepinephrine in sympathetic nerves and is coreleased into
the circulation on sympathetic activation. Little is known about the regional release of …

Neumpeptidc Y (NPYJ is a 36 amino acid prptide present in the brain, the adrenal medulla
