I42.3

Endomyocardial (eosinophilic) disease

Clinical Classification Guidelines

Inclusion Terms

  • Endomyocardial (tropical) fibrosis
  • Löffler's endocarditis

Medical Intelligence & Overview

Endomyocardial (eosinophilic) disease, also known as Löffler's endocarditis or tropical endomyocardial fibrosis, is a condition characterized by the buildup of eosinophils—a type of white blood cell—in the heart's inner lining (endocardium). This causes inflammation and scarring that impair the heart’s ability to pump blood efficiently. Although considered rare, especially outside tropical regions, understanding this condition is key to recognizing its potential impacts on heart health.

Causes & Symptoms

Clinical Causes: Eosinophilic infiltration: An abnormal increase in eosinophils can occur due to parasitic infections, certain blood disorders, or allergic conditions. Infections: Tropical regions may see higher incidences related to parasitic infections like filariasis or other helminth infestations. Immune responses: Autoimmune conditions might trigger abnormal eosinophil activity leading to tissue damage. Genetic factors: Family history or genetic predispositions may influence susceptibility. Environmental factors: Living in or traveling to tropical areas with endemic parasitic diseases increases risk.

Key Symptoms: Shortness of breath, especially during physical activity or when lying flat Fatigue and weakness Swelling in the legs, ankles, or abdomen due to fluid buildup Palpitations or irregular heartbeats Persistent cough or wheezing Fainting or dizziness in severe cases Signs of heart failure as the disease progresses

Diagnostic & Treatment

Diagnosis Path: Electrocardiogram (ECG): To detect abnormal heart rhythms Echocardiogram: Ultrasound imaging to visualize heart structure and function, revealing scarring or thickening of the endocardium MRI or CT scan: Provide detailed images of the heart tissue and degree of fibrosis Blood tests: To measure eosinophil levels and assess for underlying causes Endomyocardial biopsy: A procedure to collect tissue samples for microscopic examination, confirming eosinophilic infiltration Serological tests: To identify parasitic or infectious causes

Treatment Protocols: Anti-inflammatory medications: Corticosteroids to reduce inflammation and eosinophil activity Treatment of underlying infections: Antiparasitic or antimicrobial agents as indicated Immunosuppressive therapy: In cases related to autoimmune or allergic reactions Management of heart failure: Using medications such as diuretics, ACE inhibitors, or beta-blockers Surgical intervention: In severe cases, procedures to remove scar tissue or repair damaged heart valves Close monitoring: Regular follow-up with echocardiography and clinical assessments to track disease progression

Reimbursement claims with a date of service on or after October 1, 2015 require the use of ICD-10-CM codes.
