Outline the criteria used in noninvasive arterial physiologic testing with an ankle-brachial index (ABI) ≥1.40 being defined as noncompressible and classified into four subgroups.
Describe the role of noninvasive lower extremity imaging in patients with peripheral arterial disease (PAD), arterial calcification, and other risk factors documented in noncompressible and intermittently compressible arteries.
Discuss the importance of noninvasive physiologic lower leg testing to include ABI, toe-brachial index (TBI) with continuous wave (CW) Doppler, and arterial waveform analysis when evaluating patients with PAD.
The prevalence of noncompressible ABI represented what percentage of all patients in the article’s study cohort? A. 16% B. 11% C. 24% D. 27.4%
According to Table 2, how many male patients in the cohort with arterial noncompressible ABI were classified in the single exam occurrence (NC-S) group? A. 479 B. 276 C. 103 D. 106
According to Table 4, what was the most common risk factor for both of the compressible to noncompressible and intermittent compressibility groups? A. Chronic kidney disease B. Diabetes C. Hypertension D. Peripheral artery disease
The authors concluded that additional research may be needed to further investigate a possible increased cardiovascular risk in which patient ABI group? A. Intermittent compressibility B. Compressibility C. Noncompressiblity D. Compressible to noncompressible
What was the total number of follow-up exams performed on all 718 NC-M, C-NC, and I-C patients? A. 3,014 B. 767 C. 172 D. 1,198
