“…Positive and negative study conclusion In 18 of the 25 studies reviewed in this paper (72%; n ¼ 3449), 7,14,[19][20][21][22][23][25][26][27][28]31,[34][35][36]38,40 the authors arrived at a conclusion in favor of oscillometric ABI measurement. Studies with Table 1a Studies that compared the oscillometric with Doppler method for ankle-brachial index measurement a positive conclusion compared with those with a negative one reported a lower but not significant average Doppler-oscillometric ABI difference (0.012±0.010 vs. 0.047±0.035 P ¼ 0.38) and absolute ABI difference (0.044 ± 0.011 vs. 0.060 ± 0.021; P ¼ 0.51), and a significantly higher sensitivity for PAD diagnosis (80 ± 3% vs. 51±5%; Po0.001).…”

Automated oscillometric determination of the ankle-brachial index: a systematic review and meta-analysis

Measurement of the ankle-brachial index (ABI) using a Doppler device is widely used to identify subjects with peripheral artery disease (PAD), and those who are at high risk of cardiovascular disease. This paper presents a systematic review (Medline/ PubMed, Embase and Cochrane) and meta-analysis of studies assessing the usefulness of automated oscillometric devices for ABI estimation and PAD detection compared with the conventional Doppler method. A total of 25 studies including 4186 subjects were analyzed. A random-effects model analysis showed that the average oscillometric ABI was similar to the Doppler ABI (mean difference ± s.e. 0.020 ± 0.018, P ¼ 0.3) but that the absolute differences were significant (0.048 ± 0.009, Po0.01). The pooled correlation coefficient (r) between the oscillometric and Doppler ABI was 0.71 ± 0.05. Simultaneous arm-leg measurements resulted in a smaller difference between the average oscillometric ABI value and the average Doppler ABI value than did sequential measurements ( À0.012 ± 0.022 vs. 0.040 ± 0.026, respectively, Po0.01). The average sensitivity and specificity of the oscillometric ABI estimation in PAD diagnosis was 69 ± 6% and 96 ± 1%, respectively (with Doppler ABI taken as the reference). These data suggest that an automated ABI measurement obtained by oscillometric blood pressure monitors is a reliable and practical alternative to the conventional Doppler measurement for the detection of PAD.To increase the sensitivity of the PAD diagnosis based on an oscillometric ABI, a higher threshold of 1.0 might be preferable.

“…Electrocardiogram, bilateral brachial BP and ankle BP, and carotid arterial pulse waves were simultaneously measured in triplicate with a vascular testing device (VP-2000; Omron Healthcare, Bannockburn, IL, USA). 9 This machine was originally developed as a screening device for hypertension, peripheral artery disease (via ankle brachial index), and arterial stiffness (via pulse wave velocity), and this necessitated the use of a BP cuff on each limb (a total of four different cuffs). Carotid arterial pressure waveforms were recorded for 30 s from the left common carotid artery using an applanation tonometry sensor.…”

Association between ankle blood pressure and central arterial wave reflection

There is an increasing recognition that central aortic pressure is more relevant than brachial measure for the prediction and pathophysiology of cardiovascular disease. Central pressure is influenced by the phenomenon of arterial wave reflections returning from the peripheral vasculature, which can be quantified by augmentation index. Accordingly, the primary aim of this study was to determine the association between central augmentation index and arterial blood pressures (BPs), recorded in both the upper and lower limbs. A total of 833 apparently healthy adults of varying ages were studied. All of the BP (brachial and ankle, systolic, mean, diastolic and pulse) measurements were significantly associated with carotid augmentation index. Among them, ankle mean arterial pressure was the strongest correlate of carotid augmentation index (r ¼ 0.51, Po0.0001). This relation remained highly significant even after the influence of potential confounders was accounted for by the partial correlation analyses. Stepwise regression analyses revealed that ankle mean arterial pressure was the strongest independent predictor of carotid augmentation index. Ankle BP is strongly associated with the augmentation of central BP, and this relation is independent of other BP measures (brachial BP).
