Age Dependence of Arterial Pulse Wave Parameters Extracted From Dynamic Blood Pressure and Blood Volume Pulse Waves

Abstract

Atherosclerosis is a significant cause of mortality in the aged population, and it affects arterial wall properties causing differences in measured arterial pulse wave (PW). In this study, both dynamic arterial blood pressure PWs and blood volume PWs are analyzed. The PWs are recorded noninvasively from multiple measurement points from the upper and lower limbs from 52 healthy (22-90-year-old) volunteers without known cardiovascular diseases. For each signal, various parameters earlier proposed in the literature are computed, and 25 different novel parameters are formed by combining these parameters. The results are evaluated in terms of age and heart rate (HR) dependence of the parameters. In general, the results show that 14 out of 25 tested combined parameters have stronger age dependence than any of the individual parameters. The highest obtained linear correlation coefficients between the age and combined parameter and individual parameter equal to 0.85 ( ) and 0.79 ( ), respectively. Most of the combined parameters have also improved discrimination capability when classifying the test subjects into different age groups. This is a promising result for further studies, but indicate that the age dependence of the parameters must be taken into account in further studies with atherosclerotic patients.

Non Invasive Measurement of Hemoglobin using Optical Sensor

“…For this purpose a magnet was used which is set essentially over the radial artery of an individual whose hb concentration is to be discovered [6].Observable Red Laser light of wavelength 650 nm was used by the simple and beneficial noninvasive device for Blood Glucose Monitoring (RL-BGM) [7].The impacts of Skin thickness and Fingerprints was pretended to show the issues with Noninvasive RF Blood Glucose Sensing from Fingertips [8]. The Pulse Waves (PW) are portrayed non obtrusively from the upper and lower extremity from 52 healthy volunteers without known cardiovascular ailments [9].Dynamic Spectrum analysis is utilized for the estimation of hemoglobin concentration non obtrusively [10].…”

The effect of percutaneous transluminal angioplasty of superficial femoral artery on pulse wave features

“…In pre-processing, the signals were filtered with a Savitzky-Golay smoothing filter having a window length of 91 samples (182 ms) and a polynomial order of 2. In addition, the signals were forward-backward filtered with a finite impulse response low-pass filter having a cutoff frequency of 10 Hz, transition band of 10-12 Hz, pass band ripple of 0.05 dB, and stop band attenuation of 100 dB [15], as implemented in [16,11]. After pre-processing and feature extraction, the PWs were characterized by computing altogether 10 different PW-parameters.…”

A Novel Approach to Predict High Blood Pressure Using ABF Function

“…Heart beats are regulated by the natural pacemaker system in the heart. If the age of a person increases then pathways of the heart's pacemaker system deposits fat, which will affect the heart performance while pumping the blood [3]. As we grow older Heart muscle cells will be degenerated and becomes thin, Blood vessels performance decreases.…”
