Non-invasive assessment of pulmonary vascular resistance in pulmonary hypertension: Current knowledge and future direction [PDF]

open access: yes, 2017
Pulmonary Hypertension (PHT) is relatively common, dangerous and under-recognised. Pulmonary hypertension is not a diagnosis in itself; it is caused by a number of differing diseases each with different treatments and prognoses.

Definition, classification and diagnosis of pulmonary hypertension

open access: yesEuropean Respiratory Journal
Pulmonary hypertension (PH) is a haemodynamic condition characterised by elevation of mean pulmonary arterial pressure (mPAP) >20 mmHg, assessed by right heart catheterisation.

Pulmonary hypertension in chronic lung diseases: comparison to other pulmonary hypertension groups

open access: yesPulmonary Circulation, 2018
Group 3 pulmonary hypertension (PH) is a common complication of advanced chronic lung disease. Our hypothesis was that group 3 PH is associated with a more severe baseline presentation and a more severe prognosis compared to group 1 pulmonary arterial ...

Right Heart Size and Right Ventricular Reserve in Pulmonary Hypertension: Impact on Management and Prognosis

open access: yesDiagnostics, 2020
Various parameters reflecting right heart size, right ventricular function and capacitance have been shown to be prognostically important in patients with pulmonary hypertension (PH).

Exercise ventilatory reserve predicts survival in adult congenital heart disease associated pulmonary arterial hypertension with Eisenmenger physiology

open access: yesInternational Journal of Cardiology Congenital Heart Disease, 2022
Impaired ventilatory responses during exercise significantly contribute to breathlessness in patients with pulmonary arterial hypertension (PAH). Breathing reserve (BR) at peak exercise during cardiopulmonary exercise testing (CPET), a measure of the ...

Non-infectious pulmonary complications of hematopoietic stem cell transplantation [PDF]

open access: yes, 2014
Noninfectious pulmonary complications of hematopoietic stem cell transplant are currently more prevalent than infectious complications. Unfortunately, the pathophysiology basis is not completely understood.

YAP1::TFE3 mediates endothelial‐to‐mesenchymal plasticity in epithelioid hemangioendothelioma

open access: yesMolecular Oncology, EarlyView.
The YAP1::TFE3 fusion protein drives endothelial‐to‐mesenchymal transition (EndMT) plasticity, resulting in the loss of endothelial characteristics and gain of mesenchymal‐like properties, including resistance to anoikis, increased migratory capacity, and loss of contact growth inhibition in endothelial cells.

Three-dimensional echocardiography and 2D-3D speckle tracking imaging in chronic pulmonary hypertension. diagnostic accuracy in detecting hemodynamic signs of RV failure [PDF]

open access: yes, 2015
Background and objective. Our aim was to compare three-dimensional (3D) and 2D and 3D speckle tracking (2D-STE, 3D-STE) echocardiographic parameters with conventional right ventricular (RV) indexes in patients with chronic pulmonary hypertension (PH ...

Timing and Predictive Value of Clinical Conditions Preceding Multiple Sclerosis in the UK Biobank

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Multiple sclerosis (MS) patients often experience a higher incidence of clinical conditions before diagnosis, suggesting a prodromal phase. However, their predictive value and temporal trajectories remain underexplored. We investigated these aspects using the large UK Biobank's population‐based cohort, which provided clinical ...

Pathogenic Role of mTORC1 and mTORC2 in Pulmonary Hypertension. [PDF]

open access: yes, 2018
Concentric lung vascular wall thickening due to enhanced proliferation of pulmonary arterial smooth muscle cells is an important pathological cause for the elevated pulmonary vascular resistance reported in patients with pulmonary arterial hypertension ...
