    Red blood cell deformability, crucial for microcirculation, is significantly reduced in chronic arterial occlusive disease. This impairment is more pronounced than that caused by vascular risk factors alone.

    Area of Science:

    • Hematology
    • Vascular Biology
    • Microcirculation

    Context:

    • Chronic arterial occlusive disease affects microcirculation.
    • Red blood cell deformability is a key factor in blood flow.
    • Peripheral vascular disease impacts overall circulation health.

    Purpose:

    • To investigate alterations in red blood cell deformability in chronic arterial occlusive disease.
    • To assess whole-blood filterability as a measure of microcirculatory function.
    • To determine the influence of vascular risk factors on blood filterability.

    Summary:

    • Whole-blood filterability was significantly lower in patients with peripheral vascular disease compared to healthy controls.
    • Blood filterability decreased with an increasing number of vascular risk factors.

  • Even with similar risk factors, arteriopatic patients exhibited lower blood filterability than controls, indicating disease-specific impairment.
  • Elevated fibrinogen levels correlated significantly with reduced blood filterability.

    • Impact:

    • Highlights impaired red blood cell deformability as a characteristic of chronic arterial occlusive disease.
    • Suggests whole-blood filterability as a potential biomarker for microcirculatory dysfunction.
    • Underscores the multifactorial nature of impaired blood flow, involving both disease pathology and risk factors.
