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

We investigated the possibility of measuring aortic stiffness using ultrasound scans of the abdominal aorta and the Bramwell-u2013Hill equation. We discovered significant biases when estimating each parameter by comparing the Bramwell-u2013Hill equation to the measured values of the other two paramters based on a BlandU2013Hill regression. These findings show that the two measures are not interchangeable, and that a significant part of the bias is due to blood pressure estimation. To determine the potential sources of bias between cf-PWV and aortic pulsatility, further research is required.

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, click here. CfPWV was measured alternately by smartwatch and ComputAnalyse for each participant, and nine sets of data were collected from every participant with a 60-s interval between measurements between measurements. The stability of the two methods was tested using mean error and mean absolute error, respectively, for smartwatches. According to a Bland-Altman review, the error of 95% samples was within the range between u22121. 77 m/s and 1. 86 m/s. The Kappa value of cfPWV was 0. 79, the area under the ROC curve was 0. 97, specificity was 0. 93, negative predictive value was 0. 96, with negative predictive value of 0. 96. With the aid of an arterial stiffness test, Smartwatch can accurately calculate cfPWV to determine arterial stiffness.

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

ObjectivesThe goal of diagnosis and evaluation of hypertension is as a result of an examination and evaluation of hypertension. paraphrasedoutput:Methods and cf-PWV were recruited from December 2017 to September 2021 at Ruijin Hospital in Shanghai, China, in order to determine the risk of TOD in patients with different phenotypes of peripheral blood pressure and cf-PWV. Methods. CONCLUSDifferent profiles were based on the status of PBP and cf-PWV variables in the group with elevated pBP and cf-PWV affecting different TOD, with elevated pBP P = 0. 005, OR 2. 264, 95%CI 1. 277, 144, u20134. 016; and in the group with elevated pBP and cf-PWV; and a higher risk of ACR abnormality in the group with elevated trophy Individuals with elevated pBP are at a greater risk of ACR abnormality, compared to those with only cf-PWV elevated, who have a higher risk of LVH.

P165 EVALUATING CAROTID FEMORAL PULSE WAVE VELOCITY MEASURED BY CUFF-BASED APPROACH AGAINST THE TONOMETRY-BASED REFERENCE STANDARD IN A PAEDIATRIC POPULATION

Background: The femoral pulse wave velocity in major elastic arteries is directly related to arterial stiffness in arterial arteries and predicts future cardiovascular events. cfPWV is a marker of vascular health in children. Methods: We wanted to establish the reliability of a cuff-based cfPWV device in healthy children and see if an age-appropriate algorithm raises accuracy. With a tonometer on the carotid artery and an elevated cuff on the thigh, and a tonometer on both the carotid artery and the femoral artery as a reference method, CfPWV was determined. Children who were exposed to the reference standard had a positive response to the Cuff-based device estimates. Although the cuff-based semi-automatic approach estimates cfPWV with high conformance to the reference model, adjusting the algorithm for known leg PWV increases the accuracy of cuff-based measurements in children.

3.3 TOTAL ARTERIAL ELASTANCE IS MORE STRONGLY ASSOCIATED WITH CARDIOVASCULAR DISEASE THAN CAROTID-FEMORAL PULSE WAVE VELOCITY

In a cohort of elderly people, we compared the results of CVD and cfPWV, as well as total arterial elastance. Coronary heart disease was classified as a coronary event or revascularization based on medical record analysis and adjudicated by an independent commission. TAE were more influential than cfPWV and subdividing participants based on cfPWV had no effect on associations, according to TAE. 1. 05 [0. 95,1. 16] [0. 96,2. 11] 0. 05 [0. 96,1. 21] PWV 1. 04 [0. 93,1. 11] [0. 95,1. 12] 0. 9 0. 7 [0. 96,1. 11] 0. 4 [0. 8],1. 16] 0. 05 [0. 94,1. 11] 0. 06 [0. 93,1. 28] 0. 8 0. 05 [1. 06,1. 10] 0. 04 [0. 90],0. 93 [0. 94,1. 11] 0. 01 0. 01 [0. 94,1. 81] 1. 26 [0. 96 [0. 6 [0. 96] [0. 81] 1. 21] 1. 11 [0. 96] [0. 83] 1. 28] [0. 8] [0. 66] 0. 08 [0. 61] 1. 01] 1. 02 [0. 97,1. 21 [0. 98] [0. 96] 2. 24 [0. 97,1. 34 1. 28] [0. 96] [0. 6] [0. 93 [0. 96] [0. 96] 1. 01 [0. 96] [0. 931 [0. 87,1. 14] 1. 16 [0. 94] [0. 97,1. 11] 1. 28] [0. 96] [.

P54 Age-specific, Pressure-independent Acute Changes in Carotid-femoral Pulse Wave Velocity During Head-up Tilt

Introduction: Acute, gravity-induced blood pressure rises during head-up tilt may cause concomitant fluctuations in carotid-femoral pulse wave velocity. With tilting, both young and old people displayed increasing trends for peripheral SBP, DBP, PP, and central DBP, while central SBP remained unchanged; central SBP remained unchanged. Conclusion: With age, the escalating connection between BP and cf-PWV has become increasingly nonlinear.

Relationship between Carotid-Femoral Pulse Wave Velocity and Diet-Induced Weight Loss

Given the fact that obesity rises the risk of cardiovascular disease, cardiovascular diseases, nutritional strategies to avoid cardiovascular disease often target weight loss. Although many methods are used to induce weight loss, the most common ones are either total energy restriction, carbohydrate restriction, or dietary fat restriction. Although many techniques are used to achieve weight loss, the most common ones are either total energy restriction, carbohydrate restriction, or dietary fat restriction. Weight loss was notably linked to a decrease in cf-PWV. These results show that a weight loss program led by a low-carbohydrate diet may have a larger effect on PWV than total energy restriction. Cf-PWV: More studies are required to determine the impact of weight loss achieved by a low-fat diet on cf-PWV.

P145 MEASUREMENT OF BLOOD PRESSURE DEPENDENCY OF CAROTID-FEMORAL PULSE WAVE VELOCITY

Background: The carotid-femoral pulse wave speed is predictive of cardiovascular outcomes, but clinical interpretation is confounded by blood pressure interactions. This article discusses a procedure for PWV pressure dependency testing that is suitable for routine clinical or research use. Multiple equations describing the seated and supine measurements revealed hydrostatic BP changes across the carotid-femoral route and the pressure dependence of cfPWV. The relationship of cfPWV's pressure dependence on demographic and cardiovascular variables was quantified by a multiple linear regression. Result: The 4th out of 88 participants had unexpected rise in cfPWV with decreased BP from seated to supine positions, with unexpected rise in cfPWV from 88 subjects. According to cross-sectional reports in the remaining cohort, blood pressure dependence of cfPWV increased with brachial pulse pressure, diastolic pressure, gender, and heart rate. In these two largely stable BP positions, Measuring cfPWV aids in the estimation of the BP dependency of cfPWV.

P17 Comparisons of Carotid-femoral Pulse Wave Velocity Obtained from the Surface-distance Measurement and from the Population-derived Distance Formula: Associations with Macro- and Microvascular Alterations in Older Adults

Introduction: Inaccurate determination of arterial path length by surface-distance measurement is an inherent source of error in estimating carotid-femoral pulse wave velocity. A new innovation in determining arterial path-length by a simple distance formula for CFPWV has been shown to not only minimize intercentre measurement uncertainty but also raise the association between CFPWV and traditional cardiovascular risk factors [1]. We investigated whether the correlation between macro- and microvascular alterations with CFPWV obtained from the distance formula would be higher than that with CFPWV derived from the surface-distance measurement. CFPWV-SD and LD were also observed between CFPWV-SD and LD, IAD, and IMT, and IMT. Conclusion: The association of macro- and microvascular alterations with CFPWV-DF was not greater than that with CFPWV-SD, implying that arterial path length determination methods may not have no influence on vascular biomarker interactions with CFPWV-V.

8.11 CARDIO-ANKLE VASCULAR INDEX AND CAROTID-FEMORAL PULSE WAVE VELOCITY ARE CLOSELY ASSOCIATED WITH CHRONOLOGICAL AGE

Methods: Fifty-eight participants, age 69. 57. 46, who suffered with a transient ischaemic attack or lacunar stroke within the last two weeks, had vascular stiffness parameters, brachial, and central blood pressures measured. With Valiant VS-1500N00ae, a coronary artery beat velocity and carotid-radial pulse wave velocity were determined; Computid-femoral pulse wave velocity and carotid-radial pulse wave velocity were determined; radial augmentation index and central blood pressure were measured with Comcompo;u00ae ; Complico VS-1500N 00ae; Compulid-radial v ; vs VS-1500N VS-1500Nu00ae 00ae v v>ae vy fiduu00ae; carotid-radial pulse wave s; Comcompo v het-radial pulse wave versus e ae versus te vs measurable &u00aet-radial pulse wave vu00aete and carotid-radial pulse wave vu00aed-based versus vance versus vance versus CAVI and cfPWV were strongly linked to age in a bivariate study, but rAIx and crPWV were not. As the sole determinant factor in age and CAVI, cfPWV, crPWV, cPP, and rAIx as independent variables, a multivariate regression analysis revealed that CAVI was the only meaningful parameter related to age, with age as the dependent factor and CAVI, cfPWV, crPWV, cPP, and rAIx as independent variables.
