“…A number of comparative and validation studies have already been performed using different settings. 19,21 The aim of the present work was to provide comparative values for PWV in children, teenagers and young adults across a broad spectrum of PWV using PP, SC and VIC devices adhering to or surpassing the pediatric portion of the guidelines proposed. 29 The applanation tonometry devices PP and SC are invasively validated.…”

“…10 A multitude of various methods and techniques have been used to assess PWV in adults such as applanation tonometry, 11,12 ultrasound, 13,14 methods using mechanotransducers 15 and computerized oscillometry; 16 furthermore, a number of comparative studies with diverging results have been published concerning the comparability of the different methods. [17][18][19][20][21] Instruments based on the principle of applanation tonometry (PulsePen (PP) (DiaTecne, Milan, Italy) and Sphygmocor (SC) (AtCor, Sydney, Australia) have been extensively used. They are easily applied in adults and children and have a fair reproducibility.…”

To estimate the value of pulse wave velocity (PWV) in pediatric cardiovascular disease, prospective studies are needed. Various instruments based on different measurement principles are proposed for use in children, hence the need to test the comparability of these devices in this younger population. The objective of this study was to compare PWV measured by oscillometry (Vicorder (VIC)) with the gold standard of applanation tonometry (PulsePen (PP), Sphygmocor (SC)). PWV was measured in 98 children and young adults (age: 16.7(6.3-26.6) years (median(range)) with the above three devices at the same visit under standardized conditions. Mean PWV measured by VIC was significantly lower than that measured by SC and PP. There was no difference following path length correction of the VIC measurement (using the distance between the jugular notch and the center of the femoral cuff), (PP: 6.12(1.00), SC: 5.94(0.91), VIC: 6.14(0.75) m s À1 ). Velocities measured by the three devices showed highly significant correlations. Bland-Altman analysis revealed excellent concordance between all three devices, however, there was a small but significant proportional error in the VIC measurements showing a trend toward lower PWV measured by VIC at higher PWV values. Our study provides data on the three most frequently used instruments in pediatrics. Following path length correction of the VIC, all three devices provided comparable results. Thus, our work allows extrapolating data between previously established normal PWV values for children and forthcoming studies using these instruments to assess children at long-term risk of cardiovascular disease. The small proportional error of VIC needs additional technical development to improve the accuracy of the measurements.

BackgroundWe are the first to evaluate the prevalence of renal artery stenosis (RAS) in consecutive patients with acute myocardial infarction (AMI) referred for primary percutaneous coronary intervention from a single tertiary center. As a novelty, we assessed hydration and metabolic status and measured arterial stiffness. We elaborated a predicting model for RAS in AMI.Methods and ResultsOne hundred and eighty‐one patients with AMI underwent concomitantly primary percutaneous coronary intervention and renal angiography. We obtained data on demographics, medical history, cardiovascular risk factors, echocardiography, Killip class, and blood tests. In the first 24 hours post–primary percutaneous coronary intervention, we assessed bioimpedance through Body Composition Monitoring® and arterial stiffness through pulsed‐wave velocity, SphygmoCor®. Significant RAS (>50% lumen narrowing, RAS+) was present in 16.6% patients. In the RAS+ group we recorded significantly higher stiffness, CRUSADE score and dehydration, and more women with higher prevalence of multivascular coronary artery disease and heart failure. In our multivariate models, variables independently associated with RAS+ were previous percutaneous coronary intervention, low estimated glomerular filtration rate, multivascular coronary artery disease, and total/extracellular body water. These models had good specificity and low sensitivity.ConclusionsWe observed that RAS+ AMI patients have a particular hydration, metabolic, and endothelial profile that could generate more future major adverse cardiac events. Hence, renal angiography in AMI should be considered in specific subsets of patients.Clinical Trial Registration URL: https://www.clinicaltrials.gov/. Unique identifier: NCT02388139.

“…The cfPWV was measured as specified previously. 13 Briefly, electrocardiogram and carotid/femoral pulse waves were obtained simultaneously to calculate the transit time using the foot-to-foot method. The distance traveled by the pulse wave was calculated by subtracting the sternal notch-right carotid site from right femoral site-sternal notch distances.…”

Comparison of arterial stiffness indices measured by the Colins and SphygmoCor systems

Arterial stiffness is a known independent predictor of cardiovascular mortality. The Colins system is an easy device and has gained widespread use, but the cutoff value for high-risk central arterial stiffness is not well established. We investigated the correlation between arterial stiffness measured by the Colins system with conventional measurements from the SphygmoCor system. Arterial pulse wave velocity (PWV) and augmentation indices (AIs) were measured on a single visit using two different devices in 948 patients with hypertension or coronary artery disease. INTRODUCTIONArterial stiffening results from changes in the central arteries that are accompanied by arterial dilatation, elastin degradation, increased collagen and vascular smooth muscle cell proliferation in the intima media of the arterial wall. 1,2 Studies have shown that increased pulse wave velocity (PWV), an index of arterial stiffness, is an independent predictor of cardiovascular mortality in both the general population and in patients with hypertension. 3-5 Carotid-femoral PWV (cfPWV), which is the ratio of the distance between the carotid artery-femoral artery and the pulse wave transit time, is considered the conventional method for measuring PWV. Studies have shown that a PWV of more than 12 m s À1 is associated with increased risk of both all-cause mortality and cardiovascular mortality. 6,7 Although the measurement of heart-femoral PWV (hfPWV) and brachial-ankle PWV (baPWV) using the Colins system (VP-2000 pulse wave unit) has gained widespread popularity and usage in the clinical setting in East Asia due to its ease of use, the measurement of baPWV has been criticized because it contains components of peripheral vascular stiffness.
