Total arterial compliance, estimated by a novel method, is better related to left ventricular mass compared to aortic pulse wave velocity: The SAFAR study

Nikolaos Stergiopoulos

Aim: The investigation of the association between total arterial compliance (C-T)-estimated by a novel technique-with left ventricular mass (LVM) and hypertrophy (LVH). Our hypothesis was that C-T may be better related to LVM compared to the gold-standard ...

Non-invasive hemodynamic monitoring by electrical impedance tomography

Martin Proença

The monitoring of central hemodynamic parameters such as cardiac output (CO) and pulmonary artery pressure (PAP) is of paramount clinical importance to assess the health status of the cardiovascular system. However, their measurement requires the insertion ...

Contribution of the Arterial System and the Heart to Blood Pressure during Normal Aging - A Simulation Study

Nikolaos Stergiopoulos, Elira Maksuti, Nico Westerhof

During aging, systolic blood pressure continuously increases over time, whereas diastolic pressure first increases and then slightly decreases after middle age. These pressure changes are usually explained by changes of the arterial system alone (increase ...

Total arterial compliance estimated by a novel method and all-cause mortality in the elderly: the PROTEGER study

Nikolaos Stergiopoulos, Orestis Vardoulis

Aortic stiffness, assessed by carotid-to-femoral pulse wave velocity (PWV), often fails to predict cardiovascular (CV) risk and mortality in the very elderly. This may be due to the non-linear association between PWV and compliance or to blood pressure dec ...

First in vivo application and evaluation of a novel method for non-invasive estimation of cardiac output

Nikolaos Stergiopoulos, Orestis Vardoulis

Surgical or critically ill patients often require continuous assessment of cardiac output (CO) for diagnostic purposes or for guiding therapeutic interventions. A new method of non-invasive CO estimation has been recently developed, which is based on press ...

Experimental peripheral arterial disease: new insights into muscle glucose uptake, macrophage, and T-cell polarization during early and late stages

Rolf Gruetter, Carole Poitry-Yamate

Peripheral arterial disease (PAD) is a common disease with increasing prevalence, presenting with impaired walking ability affecting patient's quality of life. PAD epidemiology is known, however, mechanisms underlying functional muscle impairment remain un ...

Effects of Isoflurane Anesthesia on Aortic Compliance and Systemic Hemodynamics in Compliant and Noncompliant Aortas

Nikolaos Stergiopoulos

Objectives: To investigate the effect of general anesthesia on aortic compliance and other cardiovascular hemodynamics in chronically instrumented pigs with compliant and noncompliant (stiff) aortas. Design: Experimental study. Setting: University animal l ...

Systolic Hypertension Mechanisms: Effect of Global and Local Proximal Aorta Stiffening on Pulse Pressure

Nikolaos Stergiopoulos, Philippe Reymond, Nico Westerhof

Decrease in arterial compliance leads to an increased pulse pressure, as explained by the Windkessel effect. Pressure waveform is the sum of a forward running and a backward running or reflected pressure wave. When the arterial system stiffens, as a result ...

On the Estimation of Total Arterial Compliance from Aortic Pulse Wave Velocity

Nikolaos Stergiopoulos, Orestis Vardoulis

Total arterial compliance (C (T)) is a main determinant of cardiac afterload, left ventricular function and arterio-ventricular coupling. C (T) is physiologically more relevant than regional aortic stiffness. However, direct, in vivo, non-invasive, measure ...

Time course of flow-induced adaptation of carotid artery biomechanical properties, structure and zero-stress state in the arteriovenous shunt

Nikolaos Stergiopoulos

Numerous studies have provided evidence of diameter adaptation secondary to flow-overload. but with ambiguous findings vis a vis other morphological parameters and information on the biomechanical aspects of arterial adaptation is rather incomplete. We exa ...
