A constitutive formulation of arterial mechanics including vascular smooth muscle tone

Nikolaos Stergiopoulos, Martin Zulliger, Alexander Rachev

A pseudo-strain energy function (pseudo-SEF) describing the biomechanical properties of large conduit arteries under the influence of vascular smooth muscle (VSM) tone is proposed. In contrast to previous models that include the effects of smooth muscle co ...

Geometrical, functional, and histomorphometric adaptation of rat carotid artery in induced hypertension

Nikolaos Stergiopoulos, Martin Zulliger

Acute and long-term (up to 56 days) evolution of geometry, structural properties, vascular smooth muscle (VSM) tone and histomorphometric properties of the rat common carotid arteries under induced hypertension were investigated. Hypertension was induced i ...

Biomechanical adaptation of porcine carotid vascular smooth muscle to hypo and hypertension in vitro

Nikolaos Stergiopoulos, Martin Zulliger

Previous research in arterial remodeling in response to changes in blood pressure seldom included both hyper- and hypotension. To compare the effects of low and high pressure on arterial remodeling and vascular smooth muscle tone and performance, we have u ...

Relation of effective arterial elastance to arterial system properties

Nikolaos Stergiopoulos, Patrick Segers, Nico Westerhof

Effective arterial elastance (E(a)), defined as the ratio of left ventricular (LV) end-systolic pressure and stroke volume, lumps the steady and pulsatile components of the arterial load in a concise way. Combined with E(max), the slope of the LV end-systo ...

Effects of longitudinal stretch on VSM tone and distensibility of muscular conduit arteries

Nikolaos Stergiopoulos, Martin Zulliger

With progressing age, large arteries diminish their longitudinal stretch, which in extreme cases results in tortuosity. Increased age is also associated with loss of vessel distensibility. We measured pressure-diameter curves from muscular porcine carotid ...

Adaptation of conduit artery vascular smooth muscle tone to induced hypertension

Nikolaos Stergiopoulos, Jean-Jacques Meister

We studied the changes in vascular smooth muscle (VSM) cell tone during the adaptation of rat common carotids to induced hypertension. Hypertension was induced in 8 week old male Wistar rats by total ligation of the aorta between the two kidneys. Mean bloo ...

Predicting systolic and diastolic aortic blood pressure and stroke volume in the intact sheep

Nikolaos Stergiopoulos, Patrick Segers, Nico Westerhof

We developed a mathematical model describing the interaction between the heart and the arterial system. The model was constructed and tested on basis of invasive hemodynamic data in six sheep. Data from a first group of three animals (49 cardiac cycles) we ...

Model of geometrical and smooth muscle tone adaptation of carotid artery subject to step change in pressure

Nikolaos Stergiopoulos, Jean-Jacques Meister

Recent experimental studies have shown significant alterations of the vascular smooth muscle (VSM) tone when an artery is subjected to an elevation in pressure. Therefore, the VSM participates in the adaptation process not only by means of its synthetic ac ...
