Hemodynamic effects of infused arginine vasopressin in congestive heart failure

Arginine vasopressin in heart failure.

Pathogenesis of AVP Release In several animal models of low-output and high-output cardiac failure and in congestive heart failure in humans, it has been demonstrated that plasma AVP, renin activity, aldosterone and norepinephrine are significantly increased.7 Renal excretion of sodium and water is predominantly regulated by the integrity of the arterial circulation, which is determined by card...

Short-term hemodynamic effects of vasopressin V1-receptor inhibition in chronic right-sided congestive heart failure.

Arginine vasopressin is elevated in congestive heart failure. To determine the effect of arginine vasopressin upon systemic hemodynamics and regional blood flows, we administered the specific inhibitor of the vascular action of vasopressin [1-(beta-mercapto-beta,beta-cyclopentamethylenepropionic acid),2-(O-methyl)-tyrosine]-arginine vasopressin [d(CH2)5Tyr(Me)AVP] to 15 dogs with chronic right-...

Adverse hemodynamic effects of antiarrhythmic drugs in congestive heart failure.

Hemodynamic effects of intravenous butopamine in congestive heart failure.

Butopamine is chemically similar to dobutamine but, unlike dobutamine, it is not a catecholamine. Preclinical studies on dogs show that butopamine is inotropic intravenously and orally. We gave butopamine intravenously to eight patients with congestive heart failure using a progressive dose-response protocol ranging from 0.02 to 0.17 mcg/kg/min. The mean cardiac index and stroke volume index in...

Hemodynamic effects of digoxin on congestive heart failure.

To assess the hemodynamic effects of digoxin (0.01 mg/kg) on congestive heart failure, we evaluated 19 patients with decreased contraction force of left ventricle (old myocardial infarction n = 9, and dilated cardiomyopathy n = 10, group 1) and 8 patients with mechanical impaired left ventricular filing (mitral stenosis n = 8, group 2). In groups 1 and 2, heart rate and pulmonary capillary pres...
