Comparison of Accuracy of Two Different Methods to Determine Ankle-Brachial Index to Predict Peripheral Arterial Disease Severity Confirmed by Angiography
Ankle-brachial index (ABI) is conventionally derived as the ratio of higher of the 2 systolic ankle blood pressures to the higher brachial pressure (HABI method). Alternatively, ABI may be derived using the lower of the 2 systolic ankle pressures (LABI method). The objective of this study was to ass...

Zusammenfassung: | Ankle-brachial index (ABI) is conventionally derived as the ratio of higher of the 2 systolic ankle blood pressures to the higher brachial pressure (HABI method). Alternatively, ABI may be derived using the lower of the 2 systolic ankle pressures (LABI method). The objective of this study was to assess the utility and difference between 2 techniques in predicting peripheral artery disease (PAD). Participants who underwent both ABI measurement and arteriography from July 2005 to June 2010 were reviewed. Angiographic disease burden was scored semiquantitatively (0 = 75% stenosis of any lower extremity arterial segment), and PAD by angiography was defined as >50% stenosis of any 1 lower extremity arterial segment. A combined PAD disease score was calculated for each leg. A total of 130 patients were enrolled (260 limbs). The ABI was |
