[Blood filterability in ischemic heart disease].

E Pretolani, I Zoli, G Battistini

    Bollettino Della Societa Italiana Di Biologia Sperimentale
    |December 30, 1983

    Summary

    Reduced red blood cell deformability, indicated by lower whole-blood filterability, is a key factor in myocardial ischemia. Vascular risk factors significantly contribute to this blood flow alteration in ischemic heart disease.

    Area of Science:

    • Cardiovascular Physiology
    • Hematology

    Context:

    • Myocardial ischemia is often associated with impaired microcirculation.
    • Red blood cell deformability is crucial for blood flow in narrow capillaries.

    Purpose:

    • To investigate if altered red blood cell deformability is present in myocardial ischemia.
    • To assess whole-blood filterability in patients with myocardial ischemia and compare it to controls and subjects with vascular risk factors.

    Summary:

    • Whole-blood filterability was significantly lower in patients with myocardial ischemia compared to healthy controls (p < 0.001).
    • Blood filterability was also lower, though not significantly, in patients with myocardial ischemia compared to subjects with vascular risk factors.
    • The study utilized the Reid and Dormandy method for whole-blood filterability assessment.

    Impact:

    • Findings suggest that reduced red blood cell deformability is a significant factor in myocardial ischemia.
    • Vascular risk factors play a crucial role in the reduction of blood filterability observed in ischemic cardiopathology.
    • This research highlights the importance of microcirculatory function in the pathophysiology of ischemic heart disease.
