  1. Etiology
    1. Lymphocytic
    2. Acute infectious
      1. Viral illness
        1. Coxsackie Virus B (most common)
        2. Influenza
        3. Hepatitis
        4. Adenovirus
        5. HIV Infection
        6. Cytomegalovirus (CMV)
      2. Tropical Disease
        1. Trypanosoma cruzi (Chagas' Disease)
  2. Symptoms
    1. Most cases are mild and asymptomatic
    2. Palpitations
    3. Malaise
    4. Chest Pain
    5. Fever (viral Myocarditis)
    6. Symptoms secondary events
      1. Myocardial Infarction
      2. Congestive Heart Failure
    7. Infant presentation
      1. Poor feeding
      2. Lethargy
  3. Signs
    1. Pericardial Friction Rub
    2. Loud S3 Gallop
    3. Sinus Tachycardia (or other fast dysrhythmia)
      1. Out of proportion to other causes (e.g. beyond what would be expected with fever alone)
    4. Weak pulses
  4. Labs
    1. Creatine Phosphokinase (CPK) increased
    2. Sedimentation Rate (ESR) >60 mm/h
    3. Leukocytosis
  5. Diagnostics
    1. Electrocardiogram
      1. ST segment elevation progresses to T Wave inversion
      2. Normalizes in 2 months
    2. Chest XRay
      1. Cardiomegaly in 50% cases
  6. Management
    1. Inpatient management
    2. Agents used in acute viral Myocarditis (e.g. coxsachievirus)
      1. IV Ig
      2. Corticosteroids
      3. Cyclosporine

Myocarditis (C0027059)

Definition (NCI) Inflammation of the muscle tissue of the heart.
Definition (NCI) A disorder characterized by inflammation of the muscle tissue of the heart.
Definition (CHV) inflammation of the heart muscle
Definition (MSH) Inflammatory processes of the muscular walls of the heart (MYOCARDIUM) which result in injury to the cardiac muscle cells (MYOCYTES, CARDIAC). Manifestations range from subclinical to sudden death (DEATH, SUDDEN). Myocarditis in association with cardiac dysfunction is classified as inflammatory CARDIOMYOPATHY usually caused by INFECTION, autoimmune diseases, or responses to toxic substances. Myocarditis is also a common cause of DILATED CARDIOMYOPATHY and other cardiomyopathies.
Definition (CSP) inflammation of the muscular walls of the heart.
