Pulse wave velocity 24-hour monitoring with one-site measurements by oscillometry

Abstract

This review describes issues for the estimation of pulse wave velocity (PWV) under ambulatory conditions using oscillometric systems. The difference between the principles of measuring the PWV by the standard method and by oscillometry is shown, and information on device validation studies is summarized. It was concluded that currently oscillometry is a method that is very convenient to use in the 24-hour monitoring of the PWV, is relatively accurate, and is reasonably comfortable for the patient. Several indices with the same principles as those in the analysis of blood pressure in ambulatory monitoring of blood pressure, namely the assessment of load, variability, and circadian rhythm, are proposed.

Validation of the integration of technology that measures additional “vascular” indices into an ambulatory blood pressure monitoring system

“…The ability to obtain the data required to calculate PWV values using brachial waveforms acquired from a regular BP cuff has also been demonstrated previously 4–7. The accuracy of measurements produced using the Vasotens technology was “acceptable” according to the guidelines of the ARTERY Society, which were used as the basis of our study protocol 16.…”

“…The difference in time between the first wave and the second wave (ie, the reflected wave) correlates to the distance, according to the manufacturer’s instructions, and the resulting PWV is expressed as meters per second. The principle of PWV measurement using Vasotens technology has also been described previously 7,20…”

“…Recently, ABPM monitors measure or calculate other parameters that provide information about vascular wall properties have been developed. Several oscillometric ABPM systems, for example, the BPLab ® with Vasotens ® technology (OOO Petr Telegin, Nizhny Novgorod, Russia), use specific algorithms to perform pulse wave analyses based on 24-hour recordings of ABPM data and to calculate central BP 4–7…”

The “Extra-Media” Thickness of Carotid Arteries as a Novel Marker of Perivascular Visceral Adipous Tissue: Accent on the Relation With Vascular Remodelling Parameters

“…Анализ ригидности артерий выполняли с использованием технологии Vasotens [13], оцени-вали среднюю дневную скорость пульсовой волны (СПВ) в аорте. При этом определяемая данным мето-дом величина СПВ в аорте ≥7,9 м/с соответствует величине каротидно-феморальной СПВ >10 м/с [14].…”

“…Анализ ригид-ности артерий выполняли с использованием техно-логии Vasotens [13], оценивали среднесуточную ско-рость пульсовой волны (СПВ) в аорте (м/с). При этом определяемая данным методом величина сред-несуточной СПВ в аорте ≥8,3 м/с соответствует величине СПВ на участке "сонная-бедренная арте-рия" >12 м/с [14].…”
