Ten patients with congestive heart failure (CHF), in III and IV NYHA Class, were treated orally with a single dose of ibopamine ranging from 1.2-3.3 mg/kg, and were studied using the Swan-Ganz catheter and thermodilution technique. Cardiac index (CI) and stroke volume index (SVI) were increased, and mean pulmonary pressure (PAP), systemic vascular resistances (SVR) were lowered. Ibopamine incre...

Background: Vein of Galen aneurysm (VGA) is the most common form of symptomatic cerebrovascular malformation in neonates. It develops in a fetus in the first trimester of pregnancy due to unknown reasons, but it is likely to have a genetic etiology. The prognosis of VGA is usually poor, particularly in newborns with heart failure due to high-flow intracerebral shunt. Surgery and endovascular em...

Two-dimensional echocardiographic and Doppler variables and B-type natriuretic peptide (BNP) can predict outcomes in patients with congestive heart failure (CHF). However, there is a paucity of data on the relative cost-effectiveness of these modalities in predicting outcome. One hundred sixteen patients hospitalized with CHF underwent simultaneous BNP and Doppler echocardiographic examinations...

BACKGROUND Sympathetic activation and respiratory abnormalities may each be implicated in the pathophysiology of congestive heart failure (CHF). Chemoreflexes are an important mechanism regulating both sympathetic drive and breathing. We therefore tested the hypothesis that chemoreflex function is altered in CHF. METHODS AND RESULTS We compared ventilatory, sympathetic, heart rate, and blood ...
