Abstract: Objective To evaluate the value of measuring ankle brachial index (ABI) for diagnosing peripheral arterial disease(PAD)compared with conventional digital subtraction angiography (DSA) as the reference standard.Methotis A total of 383 consecutive inpatients (245 male.mean age 64.1 ±11.7 years) underwent both conventional DSA and ABI measurements.Results The rate of statin intervention was 90.9%,ACEI 69.2%,antiplatelet 96.6% and β-blockers 67.9%.The intravascular stenosis was classified into six degrees:normal,<30%,30%-49%,50%-69%,70%-89% and≥90%.Compared to the traditional gold standard (DSA) in diagnosis PDA.the ABI value decreased in proportion to the sevefity of PAD (the ABI value was 1.08±0.11,1.05±0.16,0.99±0.17,0.66±0.24,0.55±0.28 and 0.54±0.00 respectively in the six ranks).There was a significant correlation between DSA and ABI in diagnosis PAD.Conclusion ABI measurement is an accurate and reliable non-invasive altemative to conventional DSA in the assessment of lower extremity arteries in patients with peripheral arterial disease.
