Imaging hemodynamics [PDF]

open access: yesCancer and Metastasis Reviews, 2008
Microvascular permeability is a pharmacologic indicator of tumor response to therapy, and it is expected that this biomarker will evolve into a clinical surrogate endpoint and be integrated into protocols for determining patient response to antiangiogenic or antivascular therapies.

Functional assessment of coronary artery disease by intravascular ultrasound and computational fluid dynamics simulation

open access: yesRevista Portuguesa de Cardiologia, 2014
Clinical trials have shown that functional assessment of coronary stenosis by fractional flow reserve (FFR) improves clinical outcomes. Intravascular ultrasound (IVUS) complements conventional angiography, and is a powerful tool to assess atherosclerotic

The hemodynamics of counterpulsation

open access: yesThe Journal of Thoracic and Cardiovascular Surgery, 1966
Summary and conclusions 1. Synchronized counterpulsation was applied to two groups of 9 dogs with the use of a new fluid-coupled pulse generator. Multiple measurements were made of central (cardiac) and peripheral hemodynamics. 2. The counterpulsation pump performance was superior to pneumatically coupled systems previously studied.

Hemodynamics of hyperuricemia

open access: yesSeminars in Nephrology, 2005
Prolonged hyperuricemia is associated with the development of hypertension, renal arteriolosclerosis, glomerulosclerosis, and tubulointerstitial injury. It confers a greater risk than proteinuria for developing chronic renal disease and is associated with the development of hypertension.

The Impact of Left Ventricular Performance and Afterload on the Evaluation of Aortic Valve Stenosis: A 1D Mathematical Modeling Approach

open access: yesBioengineering, 2023
The transaortic valvular pressure gradient (TPG) plays a central role in decision-making for patients suffering from severe aortic stenosis. However, the flow-dependence nature of the TPG makes the diagnosis of aortic stenosis challenging since the ...

Percutaneous balloon valvuloplasty in a pregnant patient with pulmonary bioprosthetic valve stenosis

open access: yesRevista Médica del Hospital General de México, 2022
The pulmonary valve’s anomalies can lead to the obstruction of the right ventricle’s outflow tract. This leads to the right ventricle’s pressure overload, dilation, hypertrophy and eventually his malfunction.

CASP1 Gene Polymorphisms and BAT1-NFKBIL-LTA-CASP1 Gene–Gene Interactions Are Associated with Restenosis after Coronary Stenting

open access: yesBiomolecules, 2022
In the present study, we evaluated the association of the BAT1, NFKBIL, LTA, and CASP1 single nucleotide polymorphisms and the gene–gene interactions with risk of developing restenosis after coronary stenting. The allele and genotype determination of the

Machine learning-enabled estimation of cardiac output from peripheral waveforms is independent of blood pressure measurement location in an in silico population

open access: yesScientific Reports
Monitoring of cardiac output (CO) is a mainstay of hemodynamic management in the acutely or critically ill patient. Invasive determination of CO using thermodilution, albeit regarded as the gold standard, is cumbersome and bears risks inherent to ...

HSP70 governs permeability and mechanotransduction in primary human endothelial cells

open access: yesFEBS Open Bio, EarlyView.
HSP70 chemical inhibition reduces endothelial cell proliferation and increases permeability, the latter supported by normal interendothelial junctional protein distribution. HSP70 also plays a role in shear stress response, a hemodynamic force naturally present in blood vessels and correlated with vessel protection.
