“…Assessing PWV, the SphygmoCor is currently the most evaluated and commonly used device in clinical studies. However, it is known that the tonometric method of the SphygmoCor is highly operator‐dependent and requires considerable operator training to guarantee for good interobeserver and intraobserver variability 8,9,13,14 . However, in contemporary studies, it is not unusual to have multiple centers and different study staff conducting PWV measurements.…”

Carotid to femoral pulse wave velocity (PWV) is associated with an increase in cardiovascular morbidity and all‐cause mortality. Noninvasive approach has made this method applicable for the examination of larger populations. This study aimed to obtain reference values of PWV measured with the Vicorder device. PWV was obtained using the oscillometric Vicorder in 318 healthy, normotensive patients (165 women, 28.7±17.6 years, range 6–83 years). A plethysmographic sensor was placed over the right carotid region to pick up the carotid pulse wave and a blood pressure cuff was placed around the upper thigh to trace the femoral pulse wave. Path length was defined as the distance from the suprasternal notch to the top of the thigh cuff. Mean PWV was 6.1±1.4 m/s and significantly increased with age (r=.842; P<.0001). PWV was associated with mean arterial pressure (r=.546; P<.0001) and body mass index (r=.396; P<.0001). In a multiple linear regression model, age, mean arterial pressure, and body height emerged as independent markers for PWV. This study established reference values for carotid to femoral PWV derived by oscillometric measures that can now be used for risk stratification.

“… 5 Previous studies used carotid-femoral PWV (cfPWV), which measures the velocity of the pulse wave as it travels a given distance between the carotid and femoral arteries 6 and reflects the stiffness of elastic arteries. 7 A high cfPWV was significantly associated with marked declines in psychomotor speed, 8 verbal learning, and nonverbal memory 9 in older adults. Scuteri and colleagues 10 , 11 reported an association between cfPWV and CD among older adults who reported memory problems and were assessed using the Mini-Mental State Examination (MMSE).…”

BackgroundBrachial-ankle pulse wave velocity (baPWV) is inversely associated with cognitive function. However, it is not known whether baPWV predicts cognitive decline (CD) in later life. We examined whether or not baPWV is an independent risk marker of subsequent CD in a population of older Japanese.MethodsAmong 982 adults aged 65 years or older who participated in a baseline survey, 526 cognitively intact adults (Mini-Mental State Examination [MMSE] score ≥24; mean [SD] age, 71.7 [5.6] years; women, 57.8%) were followed for a period of up to 5 years. Pulse wave velocity was determined using an automated waveform analyser. Cognition was assessed by the MMSE, and CD was defined as a decrease of two points or more on the MMSE.ResultsDuring an average follow-up of 3.4 years, 85 participants (16.2%) developed CD. After controlling for important confounders, the odds ratios for CD in the highest and middle tertiles of baPWV, as compared with the lowest tertile, were 2.95 (95% confidence interval, 1.29–6.74) and 2.39 (95% confidence interval, 1.11–5.15), respectively.ConclusionsHigh baPWV was an independent predictor of CD in a general population of older adults and may be useful in the clinical evaluation of elders.

“…They were placed at the left carotid and the left femoral arteries for the recording of pressure waveforms of these arteries. This automatic waveform analyzer of form determines the upstroke of the wave and the pulse transit time on phase velocity theory (24). The distance that the pulse waves travels from the sensors at the carotid to the femoral artery was obtained based on the height by using the formula.…”

Objective: Home blood pressure (HBP) measurements are known as an important adjunct to office blood pressure (OBP) measurements in clinical practice. But little is known about the relationship between HBP and subclinical target organ damage (TOD) other than left ventricular hypertrophy (LVH). So we investigated the relationship of HBP measurements with subclinical TOD in untreated hypertensive patients. Methods: We measured ambulatory blood pressure (ABP), HBP and OBP of 93 untreated hypertensive patients (men: 60 and women: 33, mean age, 49±13 years). The ABP was recorded for 24 hours, HBP was measured for one week, and OBP was measured at least in two visits. All BP measurements were taken using automatic BP measuring device. The parameters indicating subclinical TOD were the left-ventricular mass index (LVMI) by transthoracic echocardiography, urinary albumin excretion rate (AER), brachial ankle pulse-wave velocity (PWV), and carotid intima-media thickness (IMT). Results: The LVMI was significantly correlated with systolic HBP and 24 hours systolic ABP, but not with OBP. The AER, PWV and IMT were also significantly correlated with systolic HBP and 24 hours systolic ABP. In a binary logistic regression analysis, systolic HBP, 24 hours systolic and diastolic ABP were the predictors of LVMI, AER and PWV (all p<0.05). Conclusion: Our data suggest that HBP is as good as ABP monitoring and superior to OBP measurements in regard to their association with subclinical TOD. Therefore, HBP measurements give valuable information on the subclinical TOD in hypertensive patients in addition to ABP monitoring. (Anadolu Kardiyol Derg 2014; 14: 711-8)
