Effects of sustained-release moxonidine, an imidazoline agonist, on plasma norepinephrine in patients with chronic heart failure.
BACKGROUND In chronic heart failure, sympathetic activation is increased. Moxonidine acts on central nervous system receptors to decrease sympathetic activation. We investigated the dose-response relationship of a new sustained-release (SR) preparation of moxonidine and the plasma concentration of norepinephrine in patients with chronic heart failure. METHODS AND RESULTS A total of 268 patien...
متن کاملThe effects of moxonidine, a novel imidazoline, on plasma norepinephrine in patients with congestive heart failure. Moxonidine Investigators.
OBJECTIVE To evaluate the dose response relationship of moxonidine on plasma concentration of norepinephrine during acute and chronic administration in patients with congestive heart failure (CHF). BACKGROUND Sympathetic activation is increased in heart failure. Moxonidine is an imidazoline ligand acting on the central nervous system (CNS) receptors to decrease sympathetic activation. METHO...
متن کاملInfluence of central inhibition of sympathetic nervous activity on myocardial metabolism in chronic heart failure: acute effects of the imidazoline I1-receptor agonist moxonidine.
Although beta-adrenergic blockade is beneficial in heart failure, inhibition of central sympathetic outflow using moxonidine has been associated with increased mortality. In the present study, we studied the acute effects of the imidazoline-receptor agonist moxonidine on haemodynamics, NA (noradrenaline) kinetics and myocardial metabolism. Fifteen patients with CHF (chronic heart failure) were ...
متن کاملDiurnal variation in plasma norepinephrine in patients with heart failure.
Diurnal variation in plasma norepinephrine (PNE) levels is well documented in healthy individuals but not in patients with heart failure. Therefore, we attempted to determine variations in PNE levels over 24 hours, measured hourly, in six patients with an ejection fraction below 40% and a history of heart failure of longer than 3 months. Three controls without a history of heart failure also we...
متن کاملVASODILATOR EFFECTS OF THE β -AGONIST ISOPRENALINE IN AN EXPERIMENTAL MODEL OF HEART FAILURE
Heart failure is a clinical syndrome characterized by the inability of the heart to provide nutrient supply to tissues. In 75% of cases, the underlying pathology causing heart failure in patients with cardiac death is coronary heart disease. A rabbit model of heart failure with coronary ligation was produced to mimic coronary heart disease in humans. After producing the model, two arteries ...
