Do incompressible ankle arteries (ABI ≥ 2.5) predict increased mortality compared to measurable yet abnormally high ABI (1.3-2.5) in patients with ABI > 1.3?
Patients with incompressible ankle arteries (ABI ≥ 2.5) have significantly higher overall and cardiovascular mortality compared to those with measurable but abnormally high ABI (1.3-2.5), indicating they are a particularly high-risk subgroup.
Objectives Patients with an elevated ankle brachial index (ABI) > 1.3 have a high burden of disease and poorer outcome compared to patients with a lower ABI. Previously differences between patients with ABI > 1.3 have not been studied in detail. The aim of this study was to analyze the morbidity and mortality of patients with ABI > 1.3. Methods ABI measurements were performed in the vascular laboratory of Turku university hospital 2011–2013. Patients with ABI>1.3 in at least one lower limb were included in the study and divided into 3 groups: At least one lower limb ABI 1.3–2.5 but both limbs 1.3 should be considered as high cardiovascular risk patients.
