Abstract:
OBJECTIVETo 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.
METHODSA total of 383 consecutive inpatients (245 male, mean age 64.1 +/- 11.7 years) underwent both conventional DSA and ABI measurements.
RESULTSThe rate of statin intervention was 90.9%, ACEI 69.2%, antiplatelet 96.6% and beta-blockers 67.9%. The intravascular stenosis was classified into six degrees: normal, < 30%, 30% - 49%, 50% - 69%, 70% - 89% and > or = 90%. Compared to the traditional gold standard (DSA) in diagnosis PDA, the ABI value decreased in proportion to the severity 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.
CONCLUSIONABI measurement is an accurate and reliable non-invasive alternative to conventional DSA in the assessment of lower extremity arteries in patients with peripheral arterial disease.
