    Summary

    Ankle pressure and gradients strongly correlate with walking distance in patients with peripheral artery disease. These pressure measurements are key indicators for assessing walking limitations.

    Area of Science:

    • Vascular Medicine
    • Biomedical Engineering
    • Clinical Diagnostics

    Background:

    • Obliterating atherosclerosis significantly impacts peripheral artery circulation.
    • Assessing functional limitations like walking distance is crucial for patient management.
    • Ankle pressure and pressure gradients are non-invasive markers of arterial health.

    Purpose of the Study:

    • To investigate the relationship between ankle pressure/pressure gradients and functional walking capacity.
    • To determine the correlation between pressure parameters and claudication distances.
    • To evaluate the predictive value of pressure measurements for walking ability.

    Main Methods:

    • Study involved male patients with obliterating atherosclerosis.
    • Measurements included ankle pressure, pressure gradients, and claudication distances.

  • Stepwise regression analysis was used to identify significant correlations.

    • Main Results:

    • Ankle pressure and gradients correlated with final claudication distance in early stages.
    • Both initial and final claudication distances depended on poststenotic pressure and gradients.
    • Lowest pressure in crural arteries significantly influenced walking distances.
    • A very high correlation (R=0.98) was observed between initial and final claudication distances.

    Conclusions:

    • Ankle pressure parameters are reliable indicators of walking distance in atherosclerosis.
    • Pressure measurements effectively predict functional limitations in peripheral artery disease.
    • Claudication distances are strongly linked to arterial pressure, even independent of pressure parameters.
