Association of Simultaneously Measured Limbs Blood Pressure Differences with Ankle–Brachial Index
2019
The relationship between simultaneous limbs blood pressure differences and Ankle–Brachial Index (ABI) is controversial. This paper aims to investigate the association of limbs blood pressures differences with ABI as the current non-invasive diagnosis method in clinical primary care. A cross-sectional study was performed to analysis the relationship between them. The results showed that ABI < 0.9 was independently associated with inter-arm (OR, 15.469; CI, (1.776–134.773); P = 0.013) and inter-ankle (OR, 7.189; CI, (1.010–51.179); P = 0.049) when the systolic blood pressure difference ≥15mmHg. Therefore, the simultaneous measurement of four limbs blood pressure differences can provide an aid for the non-invasive detection method of PAD in clinical primary care.
