“…Although it is not possible to analyze the carotid and femoral waves simultaneously, they can be normalized separately with the electrocardiogram (ECG) getting. 6 PWV measurements were taken under the same conditions during both examinations, after the second dialysis session (second and third dialysisfree days represent the time point when PWV is very close to the weekly middle value) in supine position after resting for at least 10 minutes, including a constant room temperature of [19][20][21] C. Baseline PWV was determined and patients were followed three years for outcomes.…”

Background/Aims: The aim of this study was to investigate all-cause and cardiovascular mortality in chronic hemodialysis patients (CHP) and to identify the determinants of mortality predictors. Methods: In this study with 3 years of follow-up period, we studied a cohort of 80 CHPs. Mean age at entry was 59.3 AE 11.8 years (duration of dialysis 5.47 AE 5.16 years). At entry, together with standard clinical and biochemical analyses, pulse wave velocity (PWV) was determined from time diversity propagation of the common carotid artery and common femoral artery flow signals by Doppler ultrasound. Results: The mean PWV (m/s) was presented at entry: in survived (12.5 AE 2.01) and deceased (13.13 AE 1.70) patients. The PWV cutoff point (by ROC curves) was 11.8. The regression coefficients (b) and Exp (b) hazard ratio coefficients of covariates in Cox-regression survival analysis in all-cause and CV outcomes was:Relative risk for exposed groups according to all-cause and CV events was 4.2976 (95% CI ¼ 1.6051-11.5071) and 14.3590 (95% CI ¼ 1.6051-11.5071), p ¼ 0.0037, respectively. Conclusions: We conclude that PWV, CRP and serum albumin are strong independent predictors of overall and CV mortality in patients undergoing dialysis.

“…Of the above techniques, Doppler flowmeter is a widely used technique and PWV measured using Doppler flowmeter has been found to be highly reproducible in able-bodied populations. 10,11 To date, PWV in the SCI population has not been fully investigated, although PWV would be highly valuable in the SCI population. 12 Conventional more invasive methods for early detection of asymptomatic CAD, are often infeasible to administer, difficult to interpret, among individuals with SCI; often precluding them from participation in some forms of diagnostic testing (i.e.…”

Background: Pulse wave velocity (PWV), which reflects arterial stiffness, is an important predictor of future coronary artery disease. The test-retest reliability of PWV has not been investigated in people with spinal cord injury (SCI). Purpose: To report the test-retest (day-to-day) reliability of PWV measurements among people with SCI, and to determine the smallest real difference (SRD) of PWV values. Participants: Twenty men (n = 19) and a woman (n = 1) with SCI (C4-T10; AIS A-D; ≥1-year post-injury; 10 with paraplegia and 10 with tetraplegia; time post-injury: 11.8 ± 8.7 years; age: 43.0 ± 12.6 years). Methods: On two occasions within a 2-week period, aortic PWV (between the common carotid and femoral artery), arm PWV (between the brachial and radial artery), and leg PWV (between femoral and posterior tibial artery) were assessed at the same time of day using Doppler flowmeters. Results: No statistically significant differences were found between days 1 and 2 in aortic PWV (day 1: 941 ± 185 cm/seconds, day 2: 917 ± 160 cm/seconds, P = 0.257), leg PWV (day 1: 1088 ± 141 cm/seconds, day 2: 1122 ± 165 cm/seconds, P = 0.099) and arm PWV (day 1: 1283 ± 185 cm/seconds, day 2: 1358 ± 256 cm/seconds, P = 0.180). The aortic and leg PWVs had high test-retest reliability (intraclass correlation coefficient: ICC = 0.920 and 0.913, respectively; P < 0.001 for both) and arm PWV had moderate test-retest reliability (ICC = 0.598, P = 0.03). SRDs for each PWV were 104 cm/seconds (aortic PWV), 97 cm/seconds (leg PWV) and 143 cm/seconds (arm PWV). Conclusion: The test-retest reliability of PWV assessment is high among patients with chronic SCI. Changes in aortic PWV values above 104 cm/seconds with repeated testing like represent true changes in health status.

“…Carotid intima-media thickness (cIMT), carotid plaques (CPs), flow-mediated dilation (FMD), aortic pulse wave velocity (PWV) and aortic augmentation index (AIx) are all examples of these non-invasive arterial morphology or functional modalities. Convincing evidence are now available showing that each one of these variables is able to add prognostic information over and above conventional VRFs and all are independent predictors of CV events [8][9][10][11][12][13][14]. For these reason all these variables are now widely accepted as surrogate markers of subclinical and even clinical atherosclerosis.…”

0.11, 1.81; p=0.027) were found in AVSc subjects than in controls, with no differences in AIx (MD: 0.76%; 95%CI: -0.97, 2.49; p=0.389). In Meta-regression analyses body mass index and triglycerides levels have an impact on the difference in IMT between cases and controls, while male gender and smoking habit were associated with the difference in the prevalence of CPs between the two groups. Conclusion:AVSc is significantly associated with altered markers of subclinical atherosclerosis, thus supporting the concept that AVSc and atherosclerosis share common etiopathological mechanism and/or risk factors. On this basis, an echocardiogram carried out to assess the state of the aortic valve would be desirable whenever an altered subclinical marker of atherosclerosis is found.
