Accuracy of Noninvasively Determined Pulmonary Artery Pressure in Dogs With Myxomatous Mitral Valve Disease
Development of pulmonary hypertension is an independent predictor of poor outcome in dogs affected by myxomatous valvular degeneration (MMVD). Systolic pulmonary arterial pressure is routinely estimated by Doppler echocardiography applying the simplified Bernoulli equation to the velocity of …

Investigation of Machine-Learning Techniques for Pulmonary Artery Pressure Estimation from Electrical Impedance Tomography Images
Pulmonary artery pressure (PAP) is measured for the diagnosis and monitoring of pathologies such as congestive heart failure. Unfortunately, current modalities used for PAP measurements have disadvantages which reduce their use. One proposal to address these issues is the measurement of PAP using a …

Development and Resolution of Pulmonary Arterial Hypertension in RAO Horses
… affected horses. Horses demonstrating severe pulmonary compromise develop concurrent secondary pulmonary hypertension. The development of pulmonary hypertension is well documented in RAO affected horses, however, it is not known how rapidly increases in pulmonary artery pressure occur after …

Echocardiographic Assessment of the Canine Right Heart: Reference Intervals and Repeatability
… echocardiographic measurements which predict pulmonary artery pressure. Materials and Methods: Phase 1) 45 healthy adult dogs. Dogs underwent one echocardiographic examination by the same operator. Phase 2) 6 randomly selected dogs from the pool of Phase 1 dogs. Dogs underwent repeated …

Exploration, processing and visualization of physiological signals from the ICU
… explored include heart rate, arterial blood pressure, pulmonary artery pressure, and central venous pressure measurements. Following an introduction to these signals, several methods are proposed for visualizing the data using time and frequency domain techniques. By way of a patient case …

A Combined In Vivo and In Vitro Approach to the Study of Endotoxemia in Swine
The cardiopulmonary effects of endotoxin administration (1 microgram/kg) were evaluated in 8-10 week old SPF-derived Yorkshire pigs, both because endotoxemia is a common and important swine problem, and because the pig is a good model for human adult respiratory distress syndrome. Physiological …

Effekte von Iloprost auf Hämodynamik und Gasaustausch beim akuten Lungenversagen : eine tierexperimentelle Studie
… distress syndrome) is characterized by an intrapulmonary mismatch between ventilation and perfusion, resulting in grave hypoxemia, pulmonary hypertension, high pulmonary right-to-left shunt and complex inflammatory events. In spite of modern proposals of therapy, it leads to a lethal disease …

Etablierung eines modifizierten Adriamycin-induzierten Herzinsuffizienzmodells am Schwein
… a continued increase of the central venous pressure, pulmonary artery pressure, pulmonary wedge pressure, and pulmonary vascular resistance, whereas cardiac output, stroke volume index, and left ventricular stroke work index decreased. These results were supported by the echocardiographic …

Cardiovascular Toxicity Induced by Fumonisin in Pigs and Horses
… have been shown to induce acute lethal pulmonary edema in pigs and leukoencephalomalacia in horses. The main purpose of these studies was to examine the cardiovascular effects of fumonisin toxicity in pigs and horses. The overall goal of the research was to expand our knowledge of …

Development and Evaluation of Generative Adversarial Networks for Predicting Central Hemodynamics
… measurement of central hemodynamic values (e.g pressures in the chambers of the heart and the pulmonary vessels). The current gold standard for obtaining these values is right heart catheterization, an invasive procedure that entails some level of risk for the patient. By contrast, other …

Portal hypertension in cirrhosis and its associated pulmonary vascular disorders
… (PH), leads to complications, including pulmonary vascular disorders, portopulmonary hypertension (PoPH), and hepatopulmonary syndrome (HPS). PoPH and HPS are poorly characterised and associated with a worse prognosis in cirrhosis. There is no consensus on screening, and they are …

In-vivo-Implantation der Mikrodiagonalpumpe II beim Kalb : Hämodynamik und Hämolyse
… The hemodynamic parameters such as mean arterial pressure, mean pulmonary artery pressure, pulmonary capillary wedge pressure and cenral venous pressure remained stable during the examination period. The pump flow was almost constant over the entire examination period with 3,1 l/min by 6000 …

Interactions between potassium channels and serotonin in pulmonary arterial hypertension
Pulmonary arterial hypertension (PAH) is a progressive disease which results from increases in mean pulmonary artery pressure and pulmonary vascular resistance. If untreated it leads to right ventricular failure and death. 5-Hydroxytryptamine (5-HT) has been implicated in the disease process and is …

Investigation of the intracellular pathways required for 5HT-induced mitogenesis and their role in pulmonary hypertension.
ABSTRACT Pulmonary arterial hypertension (PAH) is a rare and progressive disease characterised by increased pulmonary vascular resistance and elevated pulmonary artery pressure, leading to right ventricular failure and eventually death. The monoamine 5-hydroxytryptamine (5HT) has been implicated in …

Einfluss einer kontrollierten Lungenperfusion auf die pulmonalarteriellen Drücke und den pulmonalen Wassergehalt
Pulmonale Komplikationen nach Operationen mit CPB zählen zu den häufigsten Ursachen für die perioperative Morbidität. Die Ursachen für die pulmonalen Funktionsstörungen sind nicht restlos geklärt, doch vermutlich spielen Entzündungsreaktionen durch Mediatoraktivierung und die Minderdurchblutung der …

Potential cardioprotective effect of chronic, moderate consumption of reduced-alcohol wine in a rat model of pulmonary hypertension
Background: Pulmonary arterial hypertension (PAH) is a severe disease which leads to right ventricular (RV) dysfunction and possibly death. The pathophysiological process of PAH remains unclear but oxidative stress is thought to contribute to arterial and ventricular dysfunction. Red wine has …

Pulmonary Artery and Central Venous Pressures as Prognostic Indicators of Post Lung Transplant Outcome
Background The relationship between elevated mean pulmonary arterial pressure (mPAP) and central venous pressure (CVP) on poor prognosis in patients undergoing lung transplants has been widely debated. We hypothesized that not only the isolated values of mPAP and CVP, but also the combination of …
