Invasive haemodynamic evaluation of the pulmonary circulation in pulmonary hypertension.

open access: yesSwiss medical weekly, 2017
The term pulmonary hypertension refers to a serious condition characterised by high pulmonary vascular pressure, mainly as a consequence of various cardiac and respiratory diseases. Current clinical classification of pulmonary hypertension considers five

Nitric Oxide in Experimental Pulmonary Embolism [PDF]

open access: yes, 2010
Nitric oxide (NO) is an important modulator of the pulmonary circulation both at basal state and in pulmonary hypertension. Low levels of NO are detectable in exhaled gas which is believed to mirror pulmonary NO formation and elimination.

Efficacy and safety of riociguat replacing PDE-5is for patients with pulmonary arterial hypertension: A systematic review and meta-analysis

open access: yesFrontiers in Pharmacology, 2023
Introduction: Pulmonary arterial hypertension (PAH) is a rare and progressive disease. Some patients treated with phosphodiesterase type 5 inhibitors (PDE-5is) fail to reach treatment goals. As a novel soluble guanylate cyclase agonist, riociguat acts on

Numerical predictions of shear stress and cyclic stretch in the healthy pulmonary vasculature [PDF]

open access: yesarXiv, 2021
Isolated post-capillary pulmonary hypertension (Ipc-PH) occurs due to left heart failure, which contributes to 1 out of every 9 deaths in the United States. In some patients, through unknown mechanisms, Ipc-PH transitions to combined pre-/post-capillary PH (Cpc-PH), diagnosed by an increase in pulmonary vascular resistance and associated with a ...

Summary of recommendations for the haemodynamic and angiographic assessment of the pulmonary circulation. Joint statement of the Polish Cardiac Society's Working Group on Pulmonary Circulation and Association of Cardiovascular Interventions.

open access: yesKardiologia polska, 2015
Right heart catheterisation (RHC) is the 'gold standard' for haemodynamic assessment of the pulmonary circulation. For the diagnosis of pulmonary hypertension (PH), the guidelines of the European Society of Cardiology require a mean pulmonary arterial ...

Quantification of Bronchial Circulation Perfusion in Rats [PDF]

open access: yes, 2004
The bronchial circulation is thought to be the primary blood supply for pulmonary carcinomas. Thus, we have developed a method for imaging and quantifying changes in perfusion in the rat lung due to development of the bronchial circulation.

11,12-EET stimulates the association of BK channel α and β(1) subunits in mitochondria to induce pulmonary vasoconstriction [PDF]

open access: yes, 2012
In the systemic circulation, 11,12-epoxyeicosatrienoic acid (11,12-EET) elicits nitric oxide (NO)- and prostacyclin-independent vascular relaxation, partially through the activation of large conductance Ca2+-activated potassium (BK) channels. However, in

Pulmonary Vascular Reserve and Aerobic Exercise Capacity [PDF]

open access: yes, 2019
Pulmonary circulation has long been known to have specific proprieties of recruitment and distention to keep the hemodynamic pressure low even when facing very high blood flow.

Redox Regulation of Ion Channels in the Pulmonary Circulation

open access: yesAntioxidants and Redox Signaling, 2015
Significance: The pulmonary circulation is a low-pressure, low-resistance, highly compliant vasculature. In contrast to the systemic circulation, it is not primarily regulated by a central nervous control mechanism.

Absence of reflex vascular responses from the intrapulmonary circulation in anaesthetised dogs [PDF]

open access: yes, 2000
The aim of this investigation was to determine whether reflex cardiovascular responses were obtained to localised distension of the intrapulmonary arterial and venous circulations in a preparation in which the stimuli to other major reflexogenic areas ...
