“…[17][18][19] We defined PAD on the basis of ABI measurements obtained from NHANES 1999 -2000 participants aged Ն40 years during the examination component of the survey. Systolic blood pressure was measured on the right arm (brachial artery) and both ankles (posterior tibial arteries).…”

“…However, the magnitude of this problem is likely to be small because the sensitivity of our definition has been shown to be Ͼ90% in other studies. [17][18][19] Additionally, the cross-sectional nature of NHANES limits conclusions about direction or causality of associations observed in the present study. The use of self-reported data for some risk factors could underestimate prevalence, especially for health conditions such as coronary heart disease.…”

“…PAD can be determined with high sensitivity and specificity using the ratio of the systolic blood pressure in the ankle to that in the arm (ABI) (16)(17)(18). We defined PAD on the basis of ABI measurements obtained from NHANES 1999-2004 in participants aged 40 and over during the examination component of the survey.…”

“…3 The Doppler-measured ankle-brachial index (ABI) is a relatively simple and noninvasive method for the assessment of PAD and the prediction of cardiovascular risk. 1,[4][5][6] Current guidelines provided by the European Society of Hypertension-European Society of Cardiology endorse the ABI measurement as a 'recommended' test in hypertensive patients, with values o0.9 indicating advanced atherosclerosis and increased cardiovascular risk. 7 However, its clinical application is limited by the need for specialized equipment and the time required for measurement, which leads to underdiagnosis of asymptomatic PAD.…”

Automated determination of the ankle-brachial index using an oscillometric blood pressure monitor: validation vs. Doppler measurement and cardiovascular risk factor profile

The ankle-brachial index (ABI) is a method used widely for peripheral arterial disease (PAD) diagnosis and cardiovascular risk prediction. This study validated automated ABI measurements taken using an oscillometric blood pressure (BP) monitor allowing simultaneous arm-leg BP measurements. A total of 93 patients (hypertension 83%; dyslipidemia 72%; diabetes 45%; cardiovascular disease 23%; smoking 15%) were submitted to Doppler and automated ABI measurements, performed using a professional oscillometric BP monitor (Microlife WatchBP Office; triplicate simultaneous arm-leg BP measurements), in a randomized order. The mean difference between the Doppler reading (1.08±0.17) and (1) the first oscillometric ABI reading was 0.03±0.11, (2) the average of two oscillometric readings was 0.02±0.10 and (3) the average of three oscillometric readings was 0.02 ± 0.09 (Po0.01 for all). Strong correlations were found between oscillometric and Doppler ABI (r 0.80, 0.85 and 0.86 for single and average of two and three oscillometric readings, respectively; Po0.001 for all). Agreement between oscillometric and Doppler ABI in diagnosing PAD (Doppler ABI o0.9) was found in 95% of cases (j 0.79; agreement in diabetics: 94%, j 0.79). A receiver operating characteristic (ROC) curve revealed area under the curve at 0.98, with a 0.97 oscillometric ABI cutoff for optimal sensitivity (92%) and specificity (92%) in diagnosing PAD. Average time for automated ABI measurement was 5.8 vs. 9.3 min for Doppler (Po0.001). Doppler and oscillometric ABI were associated and predicted (multivariate regression analysis) by the same cardiovascular risk factors (pulse pressure, smoking and cardiovascular disease history). Automated ABI measurement using a professional BP monitor allowing simultaneous arm-leg BP measurements appears to be a reliable and faster alternative to Doppler measurement.
