5. Study Description
Brief Summary
Several methods are available to measure ankle brachial index (ABI) non-invasively. A recent scientific statement of the AHA considers the Doppler method as the reference. However because Doppler devices are not widely available in primary care, several attempts have been made to propose alternative methods, among whom oscillometric methods (automatic blood pressure machines) have attracted most attention.
We hypothesize that:
- the diagnostic characteristics (i.e. sensitivity, specificity and AUC) of the oscillometric method would be very good as compared to the Doppler method.
the oscillometric method would have better intra- and inter-observer reproducibilities as compared to the Doppler method.
