Diurnal variation in pulmonary artery pressure [PDF]

Journal of Sleep Research, 1995
SUMMARY  Previous observations have suggested that pulmonary artery pressure rises during sleep, whereas systemic artery pressure falls. A system has been developed for careful and accurate recording of pulmonary arterial pressure, and applied it to two groups of subjects: patients with heart failure, and patients with chronic stable angina.

Right ventricular-pulmonary arterial coupling and pulmonary hypertension in hemodialysis: insights into structural cardiac changes and clinical implications

Renal Failure
Objectives This cross-sectional analysis from the CZecking Heart Failure in patients with advanced Chronic Kidney Disease trial (ISRCTN18275480) examined pulmonary hypertension and right ventricular-pulmonary arterial coupling in patients on chronic ...

Transcription factors and potential therapeutic targets for pulmonary hypertension

Frontiers in Cell and Developmental Biology, 2023
Pulmonary hypertension (PH) is a refractory and fatal disease characterized by excessive pulmonary arterial cell remodeling. Uncontrolled proliferation and hypertrophy of pulmonary arterial smooth muscle cells (PASMCs), dysfunction of pulmonary arterial ...

Pulmonary arterial dilation with normal pulmonary artery pressure in sarcoidosis

Journal of Family Medicine and Primary Care, 2018
In this paper we present a clinical case that has improved on our knowledge and our curiosity about sarcoidosis. We report a case of a patient known to have pulmonary sarcoidosis, who presents with respiratory failure with severe hypercapnia. Following thorough investigations this patient was recognized to have three unique yet interrelated aspects of ...

Evaluation of factors associated with selection for coronary angiography and in‐hospital mortality among patients presenting with out‐of‐hospital cardiac arrest without ST‐segment elevation

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1159-1170, December 1, 2022., 2022
Abstract Background Clinical factors favouring coronary angiography (CA) selection and variables associated with in‐hospital mortality among patients presenting with out‐of‐hospital cardiac arrest (OHCA) without ST‐segment elevation (STE) remain unclear.

The hemodynamic characteristics of severe chronic lung disease referred for lung transplantation

Pulmonary Circulation, 2022
Severe pulmonary hypertension (PH) is not common even in patients with severe chronic lung disease (CLD) but data on hemodynamic characteristics among patients with severe CLD is scarce.

Structural and hemodynamic properties in murine pulmonary arterial networks under hypoxia-induced pulmonary hypertension [PDF]

arXiv, 2020
Detection and monitoring of patients with pulmonary hypertension, defined as mean blood pressure in the main pulmonary artery above 25 mmHg, requires a combination of imaging and hemodynamic measurements. This study demonstrates how to combine imaging data from microcomputed tomography (micro-CT) images with hemodynamic pressure and flow waveforms from

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

arXiv, 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 ...

Cognitive function in late‐stage HFpEF patients with tricuspid regurgitation undergoing transcatheter tricuspid valve intervention

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1323-1330, December 1, 2022., 2022
Abstract Objectives This study evaluates the impact of transcatheter tricuspid valve interventions (TTVI) on cognitive function (CF), quality of life (QOL), and exercise capacity in late‐stage heart failure with preserved ejection fraction (HFpEF) and relevant tricuspid regurgitation (TR).

Baicalin prevents pulmonary arterial remodeling in vivo via the AKT/ERK/NF-κB signaling pathways

Pulmonary Circulation, 2019
Pulmonary arterial hypertension is a rapidly progressive and often fatal disease. As the pathogenesis of pulmonary arterial hypertension remains unclear, there is currently no good drug for pulmonary arterial hypertension and new therapy is desperately ...
