Aim: The ankle brachial index (ABI) is a non-invasive measure for the assessment of peripheral artery disease (PAD). Currently, its use is not sufficiently implemented in general practice, because it is time-consuming. An automated test may facilitate screening for PAD. In this study we assessed the accuracy and reliability of oscillometric ABI determination compared with Doppler.
Method: A total of 99 subjects, including 27 PAD patients, with various cardiovascular risk profiles (hypertension 45,9%; cardiovascular disease 29,6%; diabetes 24,5%; dyslipidemia 38,8%; smoking 21,4%), were recruited between January 2010 and February 2011 at the Department of Cardiology. Doppler with a handheld probe (Hadeco Bidop ES-100V3) and oscillometric measurements with a validated automated blood pressure system (Datascope Acutorr Plus) were performed in a randomized order. PAD was defined as ABI below 0.9.
Results: The Spearman correlation coefficient between the Doppler and oscillometric method was 0.71 (P< 0.001). The sensitivity and specificity for the oscillometric device for detecting PAD were resp. 80% and 97%, the positive and negative predictive values were resp. 89% and 95%. The average time for Doppler and oscillometric ABI determination significantly differed between both methods (resp. 11 minutes (min) 40 seconds (s) and 4min 29s; p< 0.001). The mean ABI measured with the oscillometric device was slightly higher than with Doppler (resp. 1.03 ± 0.16 and 1.01 ± 0.19; P<0.05 by paired t-test).
Conclusion: These results show that automated ABI determination is an accurate and reliable screening method for the detection of PAD.
