Sex differences in blood pressure responses to mental stress are abolished after a single bout of exercise: underlying hemodynamic mechanisms
(Springer, 2014-05-01)
We aimed to investigate whether the pressor responses to mental stress (MS) are exaggerated in men due to heightened cardiac responses, before and after a bout of exercise. Fifteen men and 19 women underwent a protocol ...
Determining Significant Morphological and Hemodynamic Parameters to Assess the Rupture Risk of Cerebral Aneurysms
(Springer Berlin Heidelberg, 2019)
Hemodynamics and morphology are recognized as major factors in the rupture risk of cerebral aneurysms, and exploration of their relationship is necessary to establish a method that can be employed by clinicians to assess ...
Study of the Hemodynamics effects of an isolated systolic hypertension (ISH) condition on cerebral aneurysms models, using FSI simulations
(MDPI, 2021)
Featured Application
This study indicates that the shape of the pulsatile pressure has great effect on hemodynamics and therefore in the future it should be considered in the clinical treatment of cerebral aneurysms.

Use of afterload hemodynamic stress as a practical method for assessing cardiac performance in rats with heart failure
(Natl Research Council Canada-n R C Research Press, 2010-07-01)
After myocardial infarction, the hemodynamics under basal conditions might appear to be unaltered, which makes it difficult to identify cardiac dysfunction by the usual approaches. Thus, we tested the response to sudden ...
Cardiac remodeling induced by smoking: concepts, relevance, and potential mechanisms
(Inflammation & Allergy Drug Targets, 2012)
Cardiac or ventricular remodeling is characterized by molecular, cellular, and interstitial alterations that lead to changes in heart size, mass, geometry and function in response to a given insult. Currently, tobacco smoke ...
Role of the Carotid Body Chemoreflex in the Pathophysiology of Heart Failure: A Perspective from Animal Studies
(Springer New York LLC, 2015)
Non-newtonian blood modeling in intracranial aneurysm hemodynamics: Impact on the wall shear stress and oscillatory shear index metrics for ruptured and unruptured cases
(2021-07-01)
When simulating blood flow in intracranial aneurysms (IAs), the Newtonian model seems to be ubiquitous. However, analyzing the results from the few studies on this subject, the doubt remains on whether it is necessary to ...
SvO(2)-GUIDED RESUSCITATION for EXPERIMENTAL SEPTIC SHOCK: EFFECTS of FLUID INFUSION and DOBUTAMINE ON HEMODYNAMICS, INFLAMMATORY RESPONSE, and CARDIOVASCULAR OXIDATIVE STRESS
(Lippincott Williams & Wilkins, 2011-12-01)
The pathogenetic mechanisms associated to the beneficial effects of mixed venous oxygen saturation (SvO(2))-guided resuscitation during sepsis are unclear. Our purpose was to evaluate the effects of an algorithm of ...
A longitudinal study of a lateral intracranial aneurysm: identifying the hemodynamic parameters behind its inception and growth using computational fluid dynamics
(2021-03-01)
In the last two decades, the application of computational fluid dynamics (CFD) to study the blood flow in intracranial aneurysms has gained popularity since hemodynamics plays a key role in the inception, growth, and rupture ...
Hemodynamic effects of inducible nitric oxide synthase inhibition combined with sildenafil during acute pulmonary embolism
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
While endogenous nitric oxide (NO) may be relevant to the beneficial hemodynamic effects produced by sildenafil during acute pulmonary embolism (APE), huge amounts of inducible NO synthase (iNOS)derived NO may contribute ...
