P5.11 ROLE OF PRESSURE-DEPENDENT ARTERIAL OMPLIANCE IN MODULATING THE PHASE OF WAVE REFLECTIONS: IMPLICATIONS FOR LV-AS COUPLING

Artery Research, 2015
Background: Arterial compliance is pressure-dependent due to the nonhomogeneous composition of the arterial wall. Wall distending pressure varies within each cardiac cycle, thus arterial compliance is dynamic and time-varying within any given cycle.

Automating the determination of wave speed using the pu-loop method [PDF]

, 2005
The PU-loop (pressure-velocity loop) is a method for determining wave speed and relies on the linear relationship between the pressure and velocity in the absence of reflected waves.

Arterial compliance in a group of normotensive and untreated hypertensive Cameroonian subjects in Yaounde

The Pan African Medical Journal, 2016
INTRODUCTION: arterial compliance is an independent predictor of cardiovascular events. It decreases with age and this decrease is accelerated by hypertension.

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

, 2018
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.

Persistent Vascular Collagen Accumulation Alters Hemodynamic Recovery from Chronic Hypoxia [PDF]

, 2012
Pulmonary arterial hypertension (PAH) is caused by narrowing and stiffening of the pulmonary arteries that increase pulmonary vascular impedance (PVZ). In particular, small arteries narrow and large arteries stiffen. Large pulmonary artery (PA) stiffness
