Polynuclear eosinophils (PE) can harm the heart, causing conditions like eosinophilic myocarditis (EM) and chronic parietal endocarditis (CPE). Early treatment with corticosteroids or heart transplantation may be effective.

Area of Science:

  • Cardiovascular Medicine
  • Hematology
  • Immunology

Context:

  • Polynuclear eosinophils (PE) possess beneficial functions but can induce cardiac toxicity.
  • Cardiac manifestations of PE toxicity include chronic parietal endocarditis (CPE) and eosinophilic myocarditis (EM).
  • CPE encompasses Loeffler's fibroplastic endocarditis and Davies' endomyocardial fibrosis, linked to hypereosinophilic syndromes and helminthiasis, respectively.

Purpose:

  • To review the pathophysiology, clinical manifestations, and therapeutic strategies for PE-induced heart diseases.
  • To discuss the controversial nosological classification of EM and CPE and their potential relationship.
  • To explore future directions in identifying genetic predispositions to PE-induced cardiac pathology.

Summary:

  • PE can cause significant cardiac damage through the release of cytotoxic proteins.

  • Eosinophilic myocarditis (EM) and chronic parietal endocarditis (CPE) are key manifestations, with EM potentially preceding CPE.
  • Treatment involves corticosteroids and heart transplantation, while genetic factors influencing susceptibility are under investigation.

    • Impact:

    • Understanding PE cardiotoxicity is crucial for diagnosing and managing these rare but severe conditions.
    • Clarifying the relationship between EM and CPE may refine diagnostic and therapeutic approaches.
    • Identifying genetic markers could enable personalized risk assessment and preventative strategies for PE-induced heart disease.
