Accuracy Evaluation of Carotid-Femoral Pulse Wave Velocity Estimated by Smart Terminal Watch.

To determine the accuracy of the smartwatch in estimating carotid-femoral pulse wave velocity, we'll use the approximation. CfPWV was measured alternately by smartwatch and ComponentAnalyse for each participant, and nine sets of data were collected from each participant at a 60 s interval between measurements at the sitting and supine positions, according to the author. The accuracy of cfPWV measurement for smartwatches was determined using mean error and mean absolute error, respectively, while the two methods' consistency was determined using Bland-Altman analysis and concordance class correlation. According to Bland-Altman analysis, 95% samples' error was in the range between -1. 77 m/s and 1. 86 m/s. Positive predictive value was 0. 83, and negative predictive value was 0. 96, with a Kappa value of greater than ten m/s at 0. 79, the area under the ROC curve was 0. 79, specificity was 0. 90, positive predictive value was 0. 93, and negative predictive value was 0. 96. To measure arterial stiffness, Smartwatch can quickly assess cfPWV to determine arterial stiffness.

Estimation of carotid-femoral pulse wave velocity from finger photoplethysmography signal.

This project compared a new tool to determine the carotid-femoral pulse wave velocity to the gold-standard cf-PWV technique. The cf-PWV was estimated from the pulse transit time determined by processing Finapres and subject's height only as well as other variables. In 90 participants were evenly divided into three groups, Doppler ultrasound cf-PWVs and FPS-PTTs were weighed in. Multiple linear regressions were used in determining the best regression model by using MATLAB Regression Learner App. In brief mode, the discrepancies were 0. 01 m s -1 and 0. 001 m s -1; 00b1 1. 11 m s -1; -0. 051 m s -1; and 0. 01 m s -1; and 0. 1 m s -1; 0. 05 m s -1; and 0. 0001 m s -1; and 0. 01 -0. 1 m s -1 v s a The discrepancies were: 0. 79 m s -1 and 0. 01 m s -1 when using an Exponential Gaussian process regression tool in full mode: 0 - 0. 73 m s -1 and 0. 01 m s -1.

Overall and repeated measures agreement between brachial-femoral and carotid-femoral measures of pulse wave velocity in young and healthy individuals.

Methods cfPWV and bfPWV were measured in the supine and seated positions, both before and after a 3-hour bout of prolonged sitting. Using the random variance components from linear mixed-model regression, an intraclass correlation coefficient for overall agreement was calculated for overall agreement. Repeated measures agreement was calculated using repeated measurements correlation. Conclusions Complete results from 18 studies were included in the analysis. Discussion The latest results show good overall coordination and a high repeat measures agreement between bfPWV and cfPWV. bfPWV is a user-friendly alternative that conforms with cfPWV-based assessments of central arterial stiffness.

Comparison of Influence of Blood Pressure and Carotid-Femoral Pulse Wave Velocity on Target Organ Damage in Hypertension.

Objectives The assessment of target organ damage is a vital component of hypertension diagnosis and evaluation. This study aims to determine the risk of TOD in individuals with various phenotypes of peripheral blood pressure and cf-PWV. Both the four groups were significantly different, with age, body mass index and fasting blood glucose, as well as peripheral systolic blood pressure, peripheral diastolic blood pressure, and peripheral pulse pressure. PBP P = 0. 005, OR 2. 264, 94 percent 4. 016; and in the group with elevated pBP and cf-PWV; however, left ventricular hypertrophy was much higher in the group with elevated cf-PWV, although left ventricular hypertrophy was evidently higher in the group with elevated cf-PWV. Individuals with elevated pBP have an elevated risk of ACR abnormality, while individuals with only cf-PWV elevated have a higher risk of LVH.

Estimation of Aortic Stiffness with Bramwell-Hill Equation: A Comparative Analysis with Carotid-Femoral Pulse Wave Velocity.

Aortic stiffness is a significant clinical measure for predicting cardiovascular events. We investigated the possibility of measuring aortic stiffness using ultrasound scans of the abdominal aorta and the Bramwell-Hill equation. Healthy volunteers were investigated; cf-PWV measurements were obtained by arterial tonometry and a systo-diastolic pressure difference was estimated using a reliable method. We discovered significant biases when estimating each parameter by applying the Bramwell-Hill equation to the measured values of the other two paramters, which is based on a Bland-Altmann study. To determine the potential sources of bias between cf-PWV and aortic pulsatility, further research is required.
