Clinical usefulness of carotid arterial wave intensity in assessing left ventricular systolic and early diastolic performance
Wave intensity (WI) is a novel hemodynamic index, which is defined as (dP/dt)·(dU/dt) at any site of the circulation, where dP/dt and dU/dt are the derivatives of blood pressure and velocity withExpand
A new noninvasive measurement system for wave intensity: evaluation of carotid arterial wave intensity and reproducibility
Abstract. Wave intensity (WI) is a new hemodynamic index that provides information about the dynamic behavior of the heart and the vascular system and their interaction. Carotid arterial waveExpand
Relationship between the pressure and diameter of the carotid artery in humans
Abstract The purpose of this study was to examine the assumption of similarity between pressure and diameter-change waveforms in humans. We measured carotid arterial pressure and diameter change,Expand
Clinical usefulness of wave intensity analysis
TLDR
Wave intensity (WI) is a hemodynamic index, which can evaluate the working condition of the heart interacting with the arterial system. Expand
On-line noninvasive one-point measurements of pulse wave velocity
Abstract Pulse wave velocity (PWV) is a basic parameter in the dynamics of pressure and flow waves traveling in arteries. Conventional on-line methods of measuring PWV have mainly been based onExpand
Aortic blood momentum--the more the better for the ejecting heart in vivo?
OBJECTIVES The aim of the present study was to test two hypotheses: (1) the momentum of the blood flowing out of the left ventricle toward the aorta (inertia force) plays an important role in theExpand
A noninvasive method of measuring wave intensity, a new hemodynamic index: application to the carotid artery in patients with mitral regurgitation before and after surgery
SummaryWave intensity (WI) is a new hemodynamic index, which is defined as (dP/dt)(dU/dt) at any site of the circulation, where dP/dt and dU/dt are the time derivatives of blood pressure andExpand
Development of a non-invasive real-time measurement system of wave intensity
Time-normalized wave intensity (WI) is a new hemodynamic index, which is defined as (dP/dt)(dU/dt) at any site of the circulation, where dP/dt and dU/dt are the time derivatives of blood pressure andExpand
Relationship between blood pressure obtained from the upper arm with a cuff-type sphygmomanometer and central blood pressure measured with a catheter-tipped micromanometer
Recently, the importance of central blood pressure for cardiovascular risk stratification has been emphasized. Accordingly, the differences in peak systolic and bottom diastolic pressures between theExpand
Intermittent, moderate-intensity aerobic exercise for only eight weeks reduces arterial stiffness: evaluation by measurement of stiffness parameter and pressure–strain elastic modulus by use of
Background and purposeAerobic exercise has been reported to be associated with reduced arterial stiffness. However, the intensity, duration, and frequency of aerobic exercise required to improveExpand
