Increased central artery stiffness in impaired glucose metabolism and type 2 diabetes - The Hoorn study [PDF]

, 2003
Impaired glucose metabolism (IGM) and type 2 diabetes (DM-2) are associated with high cardiovascular disease risk. Increases in peripheral and central artery stiffness may represent pathophysiologic pathways through which glucose tolerance status leads ...

Hypertension in the elderly. Which are the blood pressure threshold values? [PDF]

, 2019
Managing blood pressure is often difficult in the elderly, not only because of comorbidities, but also due to vascular remodelling and the changes in the renal and endocrine physiology.

Right ventricular outflow tract velocity time integral-to-pulmonary artery systolic pressure ratio: a non-invasive metric of pulmonary arterial compliance differs across the spectrum of pulmonary hypertension. [PDF]

, 2019
Pulmonary arterial compliance (PAC), invasively assessed by the ratio of stroke volume to pulmonary arterial (PA) pulse pressure, is a sensitive marker of right ventricular (RV)-PA coupling that differs across the spectrum of pulmonary hypertension (PH ...

A time-invariant visco-elastic windkessel model relating blood flow and blood volume [PDF]

, 2009
The difference between the rate of change of cerebral blood volume (CBV) and cerebral blood flow (CBF) following stimulation is thought to be due to circumferential stress relaxation in veins (Mandeville, J.B., Marota, J.J.A., Ayata, C., Zaharchuk, G ...

What every ICU clinician needs to know about the cardiovascular effects caused by abdominal hypertension [PDF]

, 2015
The effects of increased intra-abdominal pressure (IAP) on cardiovascular function are well recognized and include a combined negative effect on preload, afterload and contractility.

Arterial stiffness acute changes following aerobic exercise in males with and without hypertension

The Journal of Clinical Hypertension, 2022
While regular exercise exposure is considered the most effective therapy to reduce arterial stiffness, the effect of acute exercise training on arterial stiffness in adults with different blood pressure (BP) levels remains unclear.

Growth factors and experimental arterial grafts [PDF]

, 2016
Background: The production of growth factors from several experimental arterial conduits was determined. Methods: We implanted 105 experimental arterial grafts that were 1 cm long in the abdominal aorta of Lewis rats (average weight, 250 g).

Cardiac contractility is a key factor in determining pulse pressure and its peripheral amplification

Frontiers in Cardiovascular Medicine, 2023
BackgroundArterial stiffening and peripheral wave reflections have been considered the major determinants of raised pulse pressure (PP) and isolated systolic hypertension, but the importance of cardiac contractility and ventricular ejection dynamics is ...

Computation of Vascular Parameters: Implementing Methodology and Performance Analysis

Biosensors, 2023
This paper presents the feasibility of automated and accurate in vivo measurements of vascular parameters using an ultrasound sensor. The continuous and non-invasive monitoring of certain parameters, such as pulse wave velocity (PWV), blood pressure (BP),

Impact of Vascular Hemodynamics on Aortic Stenosis Evaluation: New Insights Into the Pathophysiology of Normal Flow—Small Aortic Valve Area—Low Gradient Pattern

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundAbout 50% of normal‐flow/low‐gradient patients (ie, low mean gradient [MG] or peak aortic jet velocity and small aortic valve area) have severe aortic valve calcification as measured by computed tomography.
