Objective: to study the relationship of obesity with arterial stiffness and dynamics of central aortic pressure in women of different ages with preserved and lost reproductive function. Materials and methods: 161 women were examined, who were divided into 3 groups. Two groups with preserved reproductive function: group 1 consisted of 52 young women from 18 to 30 years old (23.85.3 years); group 2 - 54 women aged from 31 to menopause (415.9 years). Group 3 included 55 postmenopausal women (55.45.8 years). All women underwent a clinical examination with anthropometry; questioning; 24-hour monitoring of the dynamics of blood pressure with the determination of indicators of arterial stiffness and daily aortic central pressure; determination of the carotid-femoral pulse wave velocity (cfPWV); study of vascular stiffness by volume sphygmography. Results: women in groups 2 and 3 were comparable in terms of the prevalence of general obesity (GO). Abdominal obesity (AO) was detected in 19.2% of the 1st group; 51.9% of the 2nd and 76.4% of the 3rd group. In 1st group AO has the strongest relationship with aortic pulse wave velocity PWVao (R=0.41, p=0.002) and the corrected to HR75 augmentation index Aixao (R=0.38, p=0.005). In 2nd group AO correlates with cfPWV (R=0.4, p=0.003); GO with PWVao (R=0.38, p=0.005) and aortic cardio-ankle vascular index CAVIao (R=0.48, p=0.001). In the 2nd group AO and GO are also interconnected with central and peripheral pressure. In 3rd group AO correlates with PWVao (R=0.33, p=0.01), cfPWV (R=0.32, p=0.02); GO with the index of the double product IDP (R=0.36, p=0.01). Conclusion: it is necessary to conduct a comprehensive assessment of arterial stiffness and daily dynamics of central aortic pressure in women of all ages, suffering from obesity and, first of all, its abdominal type, in order to early diagnosis of subclinical changes in the vascular wall and central hemodynamic disturbances.

The PURPUSE of the present study is changes in function and structure of large arteries in individuals with High Normal Arterial Pressure (HNAP) to be established. MATERIAL and METHODS: Structural and functional changes in the large arteries were investigated in 80 individuals with HNAP and in 45 with optimal arterial pressure (OAP). In terms of arterial stiffness, pulse wave velocity (PWV), augmentation index (AI), central aortic pressure (CAP), pulse pressure (PP) were followed up in HNAP group. Intima media thickness (IMT), flow-induced vasodilatation (FMD), ankle-brachial index (ABI) were also studied. RESULTS: Significantly increased values of pulse wave velocity, augmentation index, central aortic pressure, pulse pressure are reported in the HNAP group. In terms of IMT and ABI, being in the reference interval, there is no significant difference between HNAP and OAP groups. The calculated cardiovascular risk (CVR) in both groups is low. CONCLUSION: Significantly higher values of pulse wave velocity, augmentation index, central aortic pressure and pulse pressure in the HNAP group are reported.

Abstract Background Non-invasive measurements of 24 h ambulatory central aortic systolic pressure (24hCASP) is now feasible method than single measurement of CASP. There is growing interest in CASP as cardiovascular risk marker beyond conventional brachial blood pressure (BP). Pulse wave velocity estimates arterial stiffness, whereas CASP is representative of the BP in major organs. Purpose To evaluate non- invasive parameters for arterial stiffness using oscillometric method and to compare 24hCASP with single measurement of CASP in well-controlled hypertensive patients to detect target organ damage (TOD). Methods A total 95 patients (57±14 years) with hypertension, were separated in two groups: 22 patients with normal EA/Ees ratio (Arterial elastance (EA) and ventricular elastance (Ees)) and 73 hypertensive patients with decrease EA/Ees ratio, marker for ventriculo-arterial coupling. EA and Ees were calculated as and – systolic pressure/stroke volume and end-systolic pressure/end-systolic volume. Parameters for arterial stiffness – 24hCASP, ambulatory central systolic pressure (CASP), 24-hour pulse wave velocity (PWV24h) and ambulatory PWV were measured non-invasively with oscillometric method by Mobil-O-graph PWA. Results Statistically significant differences in parameters of vascular stiffness were found in patients with normal ventriculo-arterial coupling in comparison with disturbed EA/Ees: 24hCASP (107.64±9.19 vs. 116.64±16.7 mm Hg, p=0.02), CAP (117.45±9.26 vs. 128.42±16.15 mm Hg, p<0.0001). There were no statistically significant differences in PWV and PWV24h. Multiple regression analysis demonstrated that CAP (B=−0.264 p=0.003; 95% CI: −0.003–0.014) is independent predictor of TOD in hypertensive patients, than 24 hour central aortic pressure. Conclusion There is no superiority of 24hCASP than single measurment of CASP. CASP could predict preclinical damage and cardiovascular outcome. Funding Acknowledgement Type of funding source: None

Background and Objectives. Chronic venous insufficiency (CVI) is a common pathology of the circulatory system and is associated with a high morbidity for the patients and causes high costs for the healthcare systems. Arterial stiffness has been shown to be a predictor of cardiovascular events and mortality. The relationship between CVI and arterial stiffness using pulse wave velocity (PWV) and augmentation index (Aix) was evaluated in this study. Methods. Sixty-two patients with the stage of C3-C5 chronic venous disease (CVD) and 48 healthy subjects were enrolled in the study. To assess arterial stiffness, all cases were evaluated with I.E.M. Mobil-O-Graph brand ambulatory blood pressure monitor device. PWV and Aix were used to assess arterial stiffness in this study. Results. The mean age was 61.9±11.05 years and 54 % of the patient population was females. PWV and Aix were significantly higher in CVI patients than controls (8.92±1.65 vs. 8.03±1.43, p=0.001; 25.51±8.14 vs. 20.15±9.49, p=0.003, respectively) and also positive linear correlation was observed between CVI and all measured arterial stiffness parameters (r=0.675 for CVI and PWV, r=0.659 for CVI and Aix, respectively). A PWV value of > 9.2 has 88.9 % sensitivity and 71.4 % specificity to predict the presence of CVI. Conclusions. PWV and Aix are the most commonly used, easy, reproducible, reliable methods in the clinic to assess arterial stiffness. Logistic regression analysis showed that PWV and Aix were the independent predictors of CVI. PWV has the sensitivity of 88.9 % and specificity of 71.4 % to detect the presence of CVI.

Background: Arterial stiffness is a strong predictor of mortality in hemodialysis patients. In this study, we aimed to investigate possible relations of arterial stiffness with volume status determined by bioimpedance analysis and aortic blood pressure parameters. Also, effects of a single hemodialysis session on these parameters were studied. Methods: A total of 75 hemodialysis patients (M/F: 43/32; mean age: 53 ± 17) were enrolled. Carotid-femoral pulse wave velocity, augmentation index, and aortic pulse pressure were measured by applanation tonometry before and after hemodialysis. Extracellular fluid and total body fluid volumes were determined by bioimpedance analysis. Results: Carotid-femoral pulse wave velocity (9.30 ± 3.30 vs 7.59 ± 2.66 m/s, p < 0.001), augmentation index (24.52 ± 9.42 vs 20.28 ± 10.19, p < 0.001), and aortic pulse pressure (38 ± 14 vs 29 ± 8 mmHg, p < 0.001) significantly decreased after hemodialysis. Pre-dialysis carotid-femoral pulse wave velocity was associated with age (r2 = 0.15, p = 0.01), total cholesterol (r2 = 0.06, p = 0.02), peripheral mean blood pressure (r2 = 0.10, p = 0.005), aortic-mean blood pressure (r2 = 0.06, p = 0.02), aortic pulse pressure (r2 = 0.14, p = 0.001), and extracellular fluid/total body fluid (r2 = 0.30, p < 0.0001). Pre-dialysis augmentation index was associated with total cholesterol (r2 = 0.06, p = 0,02), aortic-mean blood pressure (r2 = 0.16, p < 0.001), and aortic pulse pressure (r2 = 0.22, p < 0.001). Δcarotid-femoral pulse wave velocity was associated with Δaortic-mean blood pressure (r2 = 0.06, p = 0.02) and inversely correlated with baseline carotid-femoral pulse wave velocity (r2 = 0.29, p < 0.001). Pre-dialysis Δaugmentation index was significantly associated with Δaortic-mean blood pressure (r2 = 0.09, p = 0.009) and Δaortic pulse pressure (r2 = 0.06, p = 0.03) and inversely associated with baseline augmentation index (r2 = 0.14, p = 0.001). In multiple linear regression analysis (adjusted R2 = 0.46, p < 0.001) to determine the factors predicting Log carotid-femoral pulse wave velocity, extracellular fluid/total body fluid and peripheral mean blood pressure significantly predicted Log carotid-femoral pulse wave velocity (p = 0.001 and p = 0.006, respectively). Conclusion: Carotid-femoral pulse wave velocity, augmentation index, and aortic pulse pressure significantly decreased after hemodialysis. Arterial stiffness was associated with both peripheral and aortic blood pressure. Furthermore, reduction in arterial stiffness parameters was related to reduction in aortic blood pressure. Pre-dialysis carotid-femoral pulse wave velocity was associated with volume status determined by bioimpedance analysis. Volume control may improve not only the aortic blood pressure measurements but also arterial stiffness in hemodialysis patients.

Introduction: Grip strength has been associated with cardiovascular events. However, there have been no exact mechanisms explaining the association between grip strength and cardiovascular events. Hypothesis: The aim of this study was to assess whether arterial stiffness or endothelial function could mediate the association between grip strength and cardiovascular events. Methods: We studied 1508 participants (Age; 60 ± 7, Men; 47.5 %) from the Ansan cohort of the Korean Genome Epidemiology Study. Participants were assessed for grip strength, measured using a Jamar dynamometer. The central blood pressure, the augmentation index, and the pulse wave velocity were evaluated by using an applanation tonometer. Intima medial thickness was measured by B-mode ultrasonogram with a 7.5 MHz linear array transducer. Results: With increasing the grip strength, augmentation index decreased (r= -0.445, p<0.001). Pulse wave velocity (r= -0.044, p=0.109) and carotid intima medial thickness (r= -0.004, p=0.881) had no significant correlation with grip strength. Conclusions: Grip strength was inversely correlated with augmentation index. This result suggests that systemic arterial stiffness could mediate the association between grip strength and cardiovascular events.
