Separation of arterial pressure waves into their forward and backward running components

Nikolaos Stergiopoulos, Jean-Jacques Meister

A new separation technique has been developed to determine the forward and backward running arterial pressure wave components. It takes into account friction as well as nonlinear effects due to convective acceleration and to the pressure dependence of the ...

Theoretical study of dynamics of arterial wall remodeling in response to changes in blood pressure

Nikolaos Stergiopoulos, Alexander Rachev

The dynamics of arterial wall remodeling was studied on the basis of a phenomenological mathematical model. Sustained hypertension was simulated by a step increase in blood pressure. Remodeling rate equations were postulated for the evolution of the geomet ...

Contributions of vascular tone and structure to elastic properties of a medium-sized artery

Nikolaos Stergiopoulos

Isobaric compliance and distensibility of the radial artery were recently reported to be normal or slightly increased in untreated hypertensive patients. However, these findings provide no information on the intrinsic mechanical properties of the wall mate ...

Determinants of stroke volume and systolic and diastolic aortic pressure

Nikolaos Stergiopoulos, Jean-Jacques Meister, Nico Westerhof

We investigated how parameters describing the heart and the arterial system contribute to the systolic and diastolic pressures (Ps and Pd, respectively) and stroke volume (SV). We have described the heart by the varying-elastance model with six parameters ...

Modeling of the wave transmission properties of large arteries using nonlinear elastic tubes

Nikolaos Stergiopoulos, Jean-Jacques Meister

We propose a new, simple way of constructing elastic tubes which can be used to model the nonlinear elastic properties of large arteries. The tube models are constructed from a silicon elastomer (Sylgard 184, Dow Corning), which exhibits a nonlinear behavi ...

Non-invasive determination of arterial diameter and distensibility by echo-tracking techniques in hypertension

Jean-Jacques Meister

METHODOLOGY: A new non-invasive ultrasonic device was developed to characterize the biomechanical properties of medium and large peripheral arteries. Simultaneous recordings of internal diameter and blood pressure over the whole cardiac cycle are used to e ...

Non-invasive estimate of the mechanical properties of peripheral arteries from ultrasonic and photoplethysmographic measurements

Jean-Jacques Meister

The non-linear elastic response of arteries implies that their mechanical properties depend strongly on blood pressure. Thus, dynamic measurements of both the diameter and pressure curves over the whole cardiac cycle are necessary to characterise properly ...
