Key result
Pulse palpation (mean ABI 0.85) and automatic blood pressure devices (mean ABI 1.09) were not reliable alternatives to the Doppler method (mean ABI 1.03; p<0.0001 and p<0.05) for ABI measurement.
Why the study?
Does ankle-brachial index measurement by pulse palpation or automatic blood pressure device provide accurate and reproducible results compared to the Doppler method in subjects?
Cross-Sectional (n=54)
Does ankle-brachial index measurement by pulse palpation or automatic blood pressure device provide accurate and reproducible results compared to the Doppler method in subjects?
p-value: p=<0.0001
Pulse palpation and automatic blood pressure devices are not reliable alternatives to the Doppler method for measuring the ankle-brachial index.
No takes yet. Share an insight, caveat, or question.
ABI by pulse palpation or automatic devices should not yet replace Doppler; this Level-4 finding leaves open need for prospective validation.
Aboyans et al. (2008) conducted a cross-sectional in Peripheral arterial disease (n=54). Pulse palpation and automatic blood pressure devices vs. Doppler method was evaluated on Mean ankle-brachial index (ABI) and reproducibility (p=<0.0001). Pulse palpation (mean ABI 0.85) and automatic blood pressure devices (mean ABI 1.09) were not reliable alternatives to the Doppler method (mean ABI 1.03; p<0.0001 and p<0.05) for ABI measurement.
