Polymorphonuclear neutrophils (PMN) actively contribute to tissue damage in ischemic diseases. Targeting PMN offers a promising strategy for reducing infarct size and preventing events like myocardial infarction (MI) and stroke.

Area of Science:

  • Cardiovascular Research
  • Immunology
  • Pathophysiology

Background:

  • Accumulating evidence implicates polymorphonuclear neutrophils (PMN) in the development and progression of ischemic/thrombotic diseases.
  • PMN infiltration is now understood as an active contributor to infarction pathophysiology, rather than a passive consequence of ischemia.
  • The role of PMN is critical in the context of reperfusion therapies for thrombosis.

Purpose of the Study:

  • To review the established role of PMN in ischemic/thrombotic diseases.
  • To highlight the therapeutic potential of targeting PMN in reducing tissue damage and infarct size.
  • To explore the implications of PMN's role for early intervention and prophylactic strategies.

Main Methods:

  • Review of accumulated scientific evidence and research findings.

  • Analysis of the pathophysiology of PMN involvement in ischemic events.
  • Evaluation of therapeutic approaches targeting PMN in preclinical and clinical studies.

    • Main Results:

    • PMN are active participants exacerbating tissue damage in infarction.
    • Interventions preventing PMN trapping in ischemic areas effectively reduce infarct size.
    • Elevated PMN counts predict ischemic events and may indicate increased PMN activation.

    Conclusions:

    • PMN play a significant role in thrombotic diseases, contributing to pathophysiology and exacerbating damage.
    • Targeting PMN offers a viable strategy to reduce infarct size and improve outcomes following reperfusion.
    • Prophylactic strategies targeting PMN may hold potential for reducing the incidence of myocardial infarction and stroke.
