Table 3 Evaluation of Ankle Brachial Pressure Index (ABI) in terms of diagnostic methods and selected treatments

From: Peripheral artery disease assessed by ankle-brachial index in patients with established cardiovascular disease or at least one risk factor for atherothrombosis - CAREFUL Study: A national, multi-center, cross-sectional observational study

  ABI ≤ 0.90
(n = 106)
ABI >0.90
(n = 424)
Suggested diagnostic method n(%)
Conventional angiography 17(14.9)** 15(15.6)
Computed-tomography angiography 4(3.5)* 3(3.1)
Magnetic resonance angiography 23(20.2)** 10(10.4)
Ultrasonography 70(61.4)** 68(70.8)
Recommended treatment   
Exercise 83(78.3)** 95(22.4)
Revascularization 31(29.2) ** 4(0.9)
Endovascular interventions 4(3.8)* 2(0.5)
Surgery 2(1.9) 1(0.2)
  1. *p < 0.05 and **p < 0.001; compared to ratio of treatment suggestion for patients having ABI >0.90
