Abstract Background To investigate the effect of brachial–ankle pulse wave velocity (baPWV) on new-onset acute myocardial infarction (AMI). Methods A retrospective cohort study was performed for the subjects who underwent baPWV examination during the follow-up of Kailuan Study Cohort from 2010 to 2017. The observation subjects were divided into 3 groups based on the levels of baPWV: <14, 14 to <18, and ≥18 m/s. The incidence density of AMI in 3 groups was calculated. Log-rank test was used to compare the differences of cumulative AMI incidence among 3 groups. The influence of baPWV on new-onset AMI was analyzed by Cox proportional risk model and restricted cubic spline. Results A total of 41,405 subjects were included in the study. During 2.66 (1.07–5.39) years’ follow-up, 150 new-onset AMI cases were observed. The incidence density of AMI in 3 groups was 3.69, 12.79, and 26.65 per 10,000 person-years, respectively. Log-rank test result showed the cumulative AMI incidence increased gradually from the subjects with the lowest baPWV to those with the highest baPWV (P < 0.05). Compared with subjects with baPWV <14 m/s, Cox model showed that hazard ratios (95% confidence interval) of AMI in those with baPWV 14 to <18 m/s and baPWV ≥18 m/s were 1.77 (1.04–3.01) and 1.93 (1.03–3.60) after adjusting for age, sex, and other potential confounding factors, respectively. Restricted cubic spline analysis showed that there was a dose–response relationship between the hazard ratio of AMI and baPWV levels. Conclusions The increased baPWV is a risk factor for new-onset AMI.

Significant Difference

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.

Vascular Stiffness

Abstract Background and Aims Fluid overload and vascular stiffness are two independent predictors of cardiovascular events in hemodialysis (HD) patients. To date, observational and interventional studies that investigated the effect of inter- and intradialytic fluid overload changes on vascular stiffness in HD patients are very limited. We performed a scoping review to explore existing reports about effects of fluid overload on vascular stiffness in adults receiving HD treatment and to identify knowledge gaps for future research. Method We followed the framework originally developed by Arksey and O’Malley. We searched Medline, Embase, CINAHL, and Cochrane Database of systematic reviews from inception to October 29, 2019. References of review papers were screened for relevant studies not identified from the initial search until saturation is achieved. Results Of 666 eligible studies, nineteen studies met the inclusion criteria. These included clinical observational studies (n=16) and randomized controlled trials (n=3). In general, most of the identified studies had small sample size and short term of follow up. Studies use different definitions of fluid overload and vascular stiffness. Measures of relative fluid overload like the ratio of extracellular fluid/intracellular fluid, fluid overload/extracellular fluid, and/or extracellular fluid/total body fluid were used as a representative of fluid status. Pulse wave velocity and augmentation index were used interchangeably as vascular stiffness measures. The accumulated findings were inconsistent and inconclusive. There was no consensus whether intradialytic fluid volume changes affected vascular stiffness. In the majority of the observational studies, a decrease in pulse wave velocity or augmentation index correlated with a decrease in blood pressure after fluid correction by HD treatment. The randomized clinical trials used different methods and technologies for the correction of fluid overload, thereby, results were conflicting. Conclusion Current literature is insufficient to justify whether fluid overload changes have a direct effect on vascular stiffness in HD patients. The findings were conflicting which limits the comparisons of studies and generalization of findings. These knowledge gaps urge the need for further clinical studies to enhance the understanding and to improve the quality of research in this topic. This includes standardized definitions and methodologies as well as longer term of follow up.

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.
