1 A modified calculation of ankle-brachial pressure index is far more sensitive in the detection of peripheral arterial disease  Frank Schröder, MD, Nicolas Diehm, MD, Shiraz Kareem, MD, Michael Ames, MD, Alessandro Pira, MD, Uwe Zwettler, MD, Holger Lawall, MD, Curt Diehm, MD  Journal of Vascular Surgery  Volume 44, Issue 3, Pages (September 2006) DOI: /j.jvs Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

2 Fig 1 Measurement of ABI as per the current protocol, the HAP method: ABI of right side = higher of the right ankle arterial SBP (mm Hg)/higher of the two brachial SBP (mm Hg). ABI of left side = higher of the left ankle arterial SBP (mm Hg)/higher of the two brachial SBP (mm Hg). Measurement of ABI by the LAP method: ABI of right side = lower of the two right ankle SBP (mm Hg)/higher of the two brachial SBP (mm Hg). ABI of left side = lower of the two left ankle SBP (mm Hg)/higher of the two brachial SBP (mm Hg).

3 Fig 2 Sensitivity and specificity of the ankle-brachial index calculated by the high ankle pressure method (HAP) and the low ankle pressure method (LAP) method compared with the results of color-coded duplex ultrasonography.
