We recruited 60 pregnant women (G1), control group, included 25 normoglycemic pregnant (G2) included 35 women with Gestational Diabetes Mellitus (GDM). PWVft(G1: 5.99±1.23; G2:10.3±1.9; p˂0.0001) are significantly higher in diabetic group. PWVft is positively correlate to HOMAIR index Conclusion : Gestational diabetes might induce an increase of pulse wave velocity expressing increment of arterial stiffness. This last constitute an early underlying cardiovascular risk

tous les patients consécutifs opérés d’une résection colorectale programmée. Les patients étaient répartis en deux groupes selon la VOP mesurée par le pOpmètre® en période pré-opératoire: VOP+ (VOP>10m/s) et VOP- (VOP≤10m/s). Un total de 96 patients était identifié, 60 dans le groupe VOP- et 36 dans le groupe VOP+. Les patients VOP+ étaient plus à risque de présenter une FA que ceux VOP- (6.25% vs 0%) (p=0.002). Hormis la durée d’hospitalisation, il n’y avait pas de différence dans les complications opératoires immédiates entre les groupes. La VOP prédisait l’apparition d’une FA avec une sensibilité et une valeur prédictive négative de 100%. La mesure de la VOP pourrait être un examen prédictif dans le dépistage précoce des FA après chirurgie colorectale.

Purpose: To extend the existing 1D arterial network model (103 segments) of Reymond et al. to a more detailed model (143 segments) including the foot and hand circulation (radial and tibial arteries). The goal is to (i) extend the existing 1D arterial network model (103 segments) of Reymond et al. to a more detailed model (143 segments) including the foot and hand circulation (Radial and Tibial arteries); (ii) use the extending model as testing tool for pOpmètre® (finger–toe pulse wave velocity). The arterial tree dimensions and properties were taken from the literature and completed with data from patient scans. A non-linear viscoelastic constitutive law for the arterial wall was considered. Comparison of simulations with & without detailed hand and foot circulation demonstrate important differences in waveforme morphology in the distal beds. The completed model predicts pressure and flow waves in the hand and foot arteries which are in good qualitative agreement with the published in- vivo measurements. The correlation between ftPWV and aPWV was good and significant (R2 = 0.95). The Bland and Altman analysis, mean difference was 0.4 m/s, classifying the ftPWV as good agreement with reference method.

The objective is to establish a transfer function estimating the central blood pressure (CBP), calibrated with a brachial pressure cuff and using the parameters obtained with the contour analysis of the photoplethysmographic pulse measured with the pOpmètre® system. 69 subjects were included: 24 healthy subjects and 45 patients with essential hypertension aged 33 ± 8 years and 59 ± 17 years respectively. The correlation between the estimated central systolic pressure (CSP) and the reference one, was good and significant (R = 0.91 ; p<0.0001). A better correlation was found in terms of central diastolic pressure (CDP) (R = 0.92; p<0.0001). The Bland and Altman analysis, mean difference was 4 mmHg p<0.0001 (CSP) versus 3 mmHg p<0.0001 (CDP), the standard deviation of the difference was 5 mmHg (CSP) versus 4 mmHg (CDP), classifying the estimation as good agreement

Finger–toe PWV (ft-PWV) was calculated using the four algorithms.The correlation between ft-PTT and carotid–femoral PTT was very good (r 2 = 0.81, P < 0.0001, RMSE = 5.4 ms)

Data from 100 consecutive patients recruited in a French CR centre. ftPWV was measured (pOpmètre-Axelife SAS-France) at the beginning and the end of CR (mean duration = 18.3±4 days). The patients (mean age 64±11 years), males = 84%, were coronary (51%), valvular (38%), heart failure (3%) and other (8%). The risk factors were the following : current smoking (n=3), Diabetes (n=26), high blood pressure (n=58), high cholesterol (n=48), obesity (n=15) and coronary heredity (n=19), sedentarity (n=20). The maximal workload (MWL) increased from 94.9±35 to 116±37 Watts and the 6min walking test (6MWT) from 430±113 to 505±106 m (p<0.0001). The PWV decreased from 9.16±3.0 to 8.39±2.5 m/s (p<0.008). Maximal physical capacity and 6MWT were dependant of the PWV and a current CR programme seems to improve the arterial stiffness in a cardiac population.

A cross-sectional study was conducted in patients with obesity without T2DM (n=37), T2DM without obesity (n=40), T2DM plus obesity (n=43), and healthy controls (n=114). Outpatient measurements of the finger–toe PWV (ftPWV) were made. Mean ftPWV in controls and in patients with obesity, T2DM, and T2DM plus obesity was 8.32 ± 2.68, 9.50 ± 3.38, 11.29 ± 4.34, and 12.36 ± 6.67 m/s, respectively
(P < 0.0001). Outpatient-measured ftPWV was correlated with age, SBP, and ABI. It was higher in patients with T2DM and obesity compared with healthy controls. The highest ftPWV was observed in patients with both T2DM and obesity

Nine SCT carriers aged 32±9 years (7 men) were compared to 14 SCA subjects aged 29±9 years (2 men) and 22 control subjects aged 34±9 years. The cardiovascular risk (CVR) was assessed according to the Framingham Laurier score. The SCT carriers had a higher PWVft (m/s) than SCA subjects (8.2±2.2 vs 6.1±0.9m/s, P=0.004) but not different from that of healthy controls (8.2±2.2 vs 7.4±1.8m/s, P=0.33. Linear regression showed a positive relationship between PWVft and the pulse pressure (PP) (P˂0.001; r2=0.39; F=13.20). The results show that the SCT carriers have stiffer arteries than SCA subjects. Linear regressions adjusted for age, mean arterial pressure (MAP) and PP, showed that only age and PP were independently correlated with arterial stiffness in the entire population.

One hundred and four subjects (55 women, mean age 33.08 ± 11.52 years, BMI = 23 kg/m2) were enrolled in a prospective cross-sectional study. Subjects with SC (n = 78 aged 16 to 61 years) were compared to controls (AA, n = 26).
A high level arterial stiffness was associated with Sickel Cell trait carriers, especially in sedentary patients.Exercise training exerts a beneficial effect on arterial stiffness.

45 subjects were included: 18 healthy subjects and 27 patients with essential hypertension aged 32 ± 7 years and 58 ± 18 years respectively. The correlation between FT PWV and CF PWV was good and significant (r2 = 0.77; p < 0.0001). A better correlation was found in terms of transit time (r2 = 0.83; p < 0.0001). The Bland and Altman analysis, mean difference was 0.35 m/s p < 0.0001 versus -11 ms p < 0.0001, the standard deviation of the difference was 0.87 m/s versus 6.73 ms, classifying the device as good agreement with reference (Wilkinson, ARTERY RES 2010). A significant bias persisted with underestimation in older subjects.

Chez 44 transplantés reinaux, La VOP est positivement corrélée avec l’âge (r 2 = 0,16, p <0,009) et négativement avec la GFR (r 2 = 0,15, p <0,009). En utilisant un modèle de régression pas à pas (incluant le sexe, l’âge, la PAS, la PAD, la taille et le poids), seuls l’âge et la VOP restait significativement associé à la GFR.

From September to December 2015, 332 subjects aged from 18 to 95 years had a standard health check-up at the IPC Center (Paris, France) including finger to toe pulse wave velocity recording with pOpmetre®, performed by nurses
Conclusion: The very simple and quick measurement of finger to toe arterial stiffness with the pOpmètre® device, can be performed by nurses during a tight time schedule.It provides values within aortic Reference value ranges.It appears as a promising substitute to reference techniques with the advantage of simplicity for assessing PWV during standard health check- up.

Ce travail concerne la validation et la preuve du concept. Rréalisé à partir de scanner cervico-thoracique chez 28 patients. Nous avons prouvé que l’arc aortique est de même longueur quela distance entre l’os Hyoïde les sigmoïdes aortiques ; et qu’il y a un lien entre la taille et la dimension de l’Aorte. Results:There was a correlation between the Aortic segment and the distance to the Hyoïd bone (non-parametric r = 0.66, p < 0.0001) and the AV-HD distance were positively correlated to the height of the subjects (r=0.60, p<0.002).
