A Systems Engineering Approach to Modeling and Analysis of Chronic Obstructive Pulmonary Disease (COPD) [PDF]

open access: yesarXiv, 2022
Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung disease characterized by airflow limitation. This study develops a systems engineering framework for representing important mechanistic details of COPD in a model of the cardio-respiratory system.

Efficient Uncertainty Quantification in a Multiscale Model of Pulmonary Arterial and Venous Hemodynamics [PDF]

open access: yesarXiv, 2023
Computational hemodynamics models are becoming increasingly useful in the management and prognosis of complex, multiscale pathologies, including those attributed to the development of pulmonary vascular disease. However, diseases like pulmonary hypertension are heterogeneous, and affect both the proximal arteries and veins as well as the ...

“It is the fear of exercise that stops me” – attitudes and dimensions influencing physical activity in pulmonary hypertension patients

open access: yesPulmonary Circulation, 2021
Pulmonary hypertension is a progressive cardiorespiratory disease that is characterized by considerable morbidity and mortality. While physical activity can improve symptoms and quality of life, engagement in this population is suboptimal.

Hemodynamic assessment of pulmonary hypertension in mice: a model based analysis of the disease mechanism [PDF]

open access: yesarXiv, 2017
This study uses a one dimensional fluid dynamics arterial network model to infer changes in hemodynamic quantities associated with pulmonary hypertension in mice. Data for this study include blood flow and pressure measurements from the main pulmonary artery for 7 control mice with normal pulmonary function and 5 hypertensive mice with hypoxia induced ...

Computer simulation of surgical interventions for the treatment of refractory pulmonary hypertension [PDF]

open access: yesarXiv, 2021
This paper describes computer models of three interventions used for treating refractory pulmonary hypertension (RPH). These procedures create either an atrial septal defect, a ventricular septal defect, or, in the case of a Potts shunt, a patent ductus arteriosus.

Prediction of Prognostic Hemodynamic Indices in Pulmonary Hypertension Using Non-Invasive Parameters

open access: yesDiagnostics, 2020
Effective targeted therapy of pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) requires regular risk stratification.

Effect of ambrisentan in patients with systemic sclerosis and mild pulmonary arterial hypertension: long-term follow-up data from EDITA study

open access: yesArthritis Research & Therapy
Background In the EDITA trial, patients with systemic sclerosis (SSc) and mild pulmonary vascular disease (PVD) treated with ambrisentan had a significant decline of pulmonary vascular resistance (PVR) but not of mean pulmonary arterial pressure (mPAP ...

DDAH1 regulates apoptosis and angiogenesis in human fetal pulmonary microvascular endothelial cells

open access: yesPhysiological Reports, 2019
Nitric Oxide (NO) is an endogenous pulmonary vasodilator produced by endothelial NO synthase (eNOS). Asymmetric dimethyl L‐arginine (ADMA) is an endogenous inhibitor of eNOS activity.

Safety, tolerability, and efficacy of an in‐class combination therapy switch from bosentan plus sildenafil to ambrisentan plus tadalafil in children with pulmonary arterial hypertension

open access: yesPulmonary Circulation
The aim of this single‐centre retrospective observational study was to evaluate the safety, tolerability, and efficacy of an in‐class combination therapy switch from bosentan plus sildenafil to ambrisentan plus tadalafil in children with pulmonary ...

Patient engagement and self-management in pulmonary arterial hypertension

open access: yesEuropean Respiratory Review, 2016
Improved care in pulmonary arterial hypertension has led to increased longevity for patients, with a paralleled evolution in the nature of their needs.
