Clinical and haemodynamic evaluation of chronic thromboembolic pulmonary hypertension patients scheduled for pulmonary thromboendarterectomy: Is schistosomiasis hypertension an important confounding factor?
(Faculdade de Medicina / USP, 2010)
INTRODUCTION: Chronic thromboembolic pulmonary hypertension is a disease affecting approximately 4,000 people per year in the United States. The incidence rate in Brazil, however, is unknown. The estimated survival for ...
Adrenomedullin induces pulmonary vasodilation but does not attenuate pulmonary hypertension in a sheep model of acute pulmonary embolism
(Elsevier B. V., 2015-10-15)
The pulmonary vasodilation induced by adrenomedullin may be beneficial in the acute pulmonary embolism (APE) setting. This study examined effects of adrenomedullin in sheep with microsphere-induced APE. Twenty four ...
Can we start to think about consensus-oriented clinical practices?

Revisiting the role of TRP, orai, and ASIC channels in the pulmonary arterial response to hypoxia
(Frontiers Media S.A., 2018)
© 2018 Reyes, Castillo-Galán, Hernandez, Herrera, Ebensperger and Llanos. The pulmonary arteries are exquisitely responsive to oxygen changes. They rapidly and proportionally contract as arterial PO2 decrease, and they ...
Fístula arteriovenosa pulmonar maciça. Causa rara, potencialmente curável de hipóxia neonatal.
(1996-06-01)
The case of a six-day-old neonate admitted in an emergency situation because of dyspnea and increasing cyanosis is reported. Despite abnormal opacification on the chest X-ray and left ventricular overload on the electrocardiogram ...
Hypoxic pulmonary vasoconstriction in reptiles: a comparative study of four species with different lung structures and pulmonary blood pressures
(Amer Physiological Soc, 2005-11-01)
Low O-2 levels in the lungs of birds and mammals cause constriction of the pulmonary vasculature that elevates resistance to pulmonary blood flow and increases pulmonary blood pressure. This hypoxic pulmonary vasoconstriction ...
Unicentric study of cell therapy in chronic obstructive pulmonary disease/pulmonary emphysema
(Dove Medical Press Ltd, 2011-01-01)
Within the chronic obstructive pulmonary disease (COPD) spectrum, lung emphysema presents, as a primarily histopathologic feature, the destruction of pulmonary parenchyma and, accordingly, an increase in the airflow ...
Long-term exposure to high-altitude chronic hypoxia during gestation induces neonatal pulmonary hypertension at sea level
(2010)
We determined whether postnatal pulmonary hypertension induced by 70% of pregnancy at high altitude (HA) persists once the offspring return to sea level and investigated pulmonary vascular mechanisms operating under these ...
Melatonin decreases pulmonary vascular remodeling and oxygen sensitivity in pulmonary hypertensive newborn lambs
(Frontiers media SA, 2018)
Background: Chronic hypoxia and oxidative stress during gestation lead to pulmonary hypertension of the neonate (PHN), a condition characterized by abnormal pulmonary arterial reactivity and remodeling. Melatonin has strong ...
