PULMONARY HYPERTENSION Treatment of canine pulmonary hypertension: effects of norepinephrine and isoproterenol on pulmonary vascular pressure-flow characteristics
Pulmonary vascular flow resistive properties may be described by mean pulmonary arterial pressure (PAP)-cardiac output (CO) plots. The slope of the PAP-CO relationship defines the incremental resistance and the extrapolated pressure intercept defines the effective outflow pressure. We investigated effects of norepinephrine (1 1 dogs) and isoproterenol (seven dogs) on the pulmonary vascular PAP-...
متن کاملInteratrial shunt for chronic pulmonary hypertension: differential impact of low-flow vs. high-flow shunting.
The purpose of the present study was to determine for the first time the qualitative and quantitative impact of varying degrees of interatrial shunting on right heart dynamics and systemic perfusion in subjects with chronic pulmonary hypertension (CPH). Eight dogs underwent 3 mo of progressive pulmonary artery banding, following which right atrial and ventricular end-systolic and end-diastolic ...
متن کاملPulmonary capillary pressure in pulmonary hypertension
INTRODUCTION Pulmonary capillary pressure (PCP), together with the time constants of the various vascular compartments, define the dynamics of the pulmonary vascular system. Our objective in the present study was to estimate PCPs and time constants of the vascular system in patients with idiopathic pulmonary arterial hypertension (IPAH), and compare them with these measures in patients with acu...
متن کاملMore pressure on pulmonary hypertension.
PH describes a group of devastating diseases, comprising idiopathic and associated/secondary forms, which cause breathlessness, loss of exercise capacity and death due to elevated pulmonary artery pressure and subsequent right heart failure [1]. Pulmonary arterial hypertension (PAH) is defined by an elevation of the mean pulmonary artery pressure above 25 mmHg at rest and/or 30 mmHg during exer...
متن کاملChronic infusion of nitric oxide in experimental pulmonary hypertension: pulmonary pressure-flow analysis.
Inhaled-nitric oxide (NO) is a selective pulmonary vasodilator in short-term clinical studies. Use of NO inhalation in chronic pulmonary hypertension is complicated by potential problems with ambulatory NO delivery. We hypothesized that long-term infusion of NO solution into the central venous circulation, which did not suffer from this drawback, might reduce chronic pulmonary hypertension. Sat...
