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

Abstract

BackgroundThe objective of this study was to validate the novel integration of oscillometric (Vasotens®) technology into a BPLab® ambulatory blood pressure (BP) monitoring system to measure central BP, the aortic augmentation index, and pulse wave velocity (PWV) compared with the recommended and widely accepted tonometric method.MethodsThe ARTERY Society guidelines for comparison of PWV measurement techniques were used as the basis for recruitment of 99 individuals (mean age 44±19 years, 52 males). The standard for comparison was the conventional “classic” SphygmoCor device.ResultsAccordance of the two methods was satisfactory (r=0.98, mean difference of 2.9±3.5 mmHg for central systolic BP; r=0.98, mean difference of −1.1±2.3 mmHg for central diastolic BP; r=0.83, mean difference of −2.6%±13% for aortic augmentation index; r=0.85, mean difference of 0.69±1.4 for PWV).ConclusionThe performance of Vasotens algorithms using an oscillometric ambulatory BP monitoring system is feasible for accurate diagnosis, risk assessment, and evaluation of the effects of antihypertensive drugs.

Cardiovascular features of possible autonomous cortisol secretion in patients with adrenal incidentalomas

“…Cardiac MRI or aortic catheterization would have provided more definitive findings. However, they are more affordable, have good reproducibility and are often used in the clinical setting for population studies (14,31,32), expanding the applicability of our findings. Finally, some recent reports suggested that patients with NFA may also carry an increased CV risk compared with the general population, thus our study may underestimate the magnitude of cardiac damage associated with pACS.…”

Comparison of the BPLab® sphygmomanometer for ambulatory blood pressure monitoring with mercury sphygmomanometry in pregnant women: validation study according to the British Hypertension Society protocol

“… 7 , 11 Moreover, the device was validated for measuring central aortic pressure and parameters of arterial stiffness. 12 – 14 It provides normative data for arterial stiffness and central BP indices and allows studying the feasibility of BPLab indices in daily life dynamic conditions. 15 , 16 We believe that this is an additional advantage of BPLab use for ABPM in the antenatal clinic, in the pregnancy day assessment unit, or when admitted to the antenatal ward for hypertension management.…”

Validation of the BPLab® 24-hour blood pressure monitoring system in a pediatric population according to the 1993 British Hypertension Society protocol

“…The BPLab ABPM device is known to have accuracy class “A/A” for measuring peripheral arterial BP in adults. 8 Moreover, the device was clinically validated for measuring central aortic pressure and parameters of arterial stiffness, 9 – 11 which provides normative data for arterial stiffness and central BP indices. 12 However, validation of the accuracy of the device in the pediatric population has not been performed as yet.…”
