COVID-19 patients with cardiovascular comorbidities have higher mortality. According to a recent systematic review and meta-analysis,acute cardiac injury with troponin levels greater than 28 pg/ml was detected in 12.4% of confirmed COVID-19 patients.[1]Acute Myocardial Infarction is defined as an acute myocardial injury with clinical evidence of acute myocardial ischemia plus rise and/or fall of cardiac troponin values with at least one value above the 99th percentile upper reference limit and at least one of the following:Symptoms of myocardial ischemia including new ischemic ECG changes, development of pathological Q waves, imaging evidence of new loss of viable myocardium or new regional wall motion abnormality in a pattern consistent with an ischemic etiology. Identification of a coronary thrombus by angiography or autopsy (not for type 2 or 3 MI).[2]





Diagnosis

Diagnostic Criteria

In May 2020, the Centers for Disease Control and Prevention (CDC) set the criteria for multisystem inflammatory syndrome in children (MIS-C):[3]

  • Severe disease course leading to hospitalization
  • Individuals younger than 21 years old
  • Fever (body temperature, >38.0°C) or report of subjective fever present at least 24 hours
  • Laboratory evidence of inflammation
  • Multisystem organ involvement (at least two systems)
  • Laboratory-confirmed SARS-CoV-2 infection

History and Symptoms

COVID-19 associated multisystem inflammatory syndrome is associated with the following symptoms:[3]

Physical Examination

COVID-19 associated multisystem inflammatory syndrome is associated with the following physical examination findings:[3]

Laboratory Findings

COVID-19 associated multisystem inflammatory syndrome is associated with the following laboratory findings:[3]

Less common laboratory findings include:

Inflammatory biomarkers

Elevation of inflammatory markers including ESR, C reactive protein, and procalcitonin are usually seen in MIS-C. Increased level of Interleukin-6 (IL-6), Interleukin-10(IL-10) d-dimer, serum ferritin, prothrombin time have also been seen in MIS-C.

Cardiac biomarkers

Elevation of cardic enzymes including cardiac troponins (cardiac troponin I(cTnI) and cardiac troponin T (cTnT)) and Brain natriuretic peptide (BNP)) has been observed in MIS-C patients.

Electrocardiogram

X-ray

  • X-ray of patients with COVID-19 associated multiorgan system inflammatory syndrome may be normal. When abnormal, findings may include the followings:[4]
    • Peribronchial cuffing
    • Perihilar interstitial thickening
    • Perihilar opacification
    • Perihilar consolidation
    • Low volume pleural effusion affecting both lungs
    • Left lower lobe atelectasis

Echocardiography or Ultrasound

  • To view the echocardiographic findings on COVID-19, click here.

Treatment

Medical Therapy

  • All the children with MIS-C are treated as suspected COVID-19.
  • Mild to Moderate cases of MIS-C are managed supportively.[5][6]
  • Supplemental oxygen is required in children with low oxygen saturation.[6]
  • Fluid resuscitation in 10 ml/kg aliquots with reevaluation after each bolus. Maintain euvolemia. Avoid hypervolemia.[6]
  • Anti-inflammatory treatments with Intravenous immunoglobulin(IVIG) with or without corticosteroids have shown a good response rate.[5][6]
  • Aspirin has been used primarily for its antiplatelet effect. It is recommended in all patients with MIS-C.[5][6]
  • Anakinra is considered if fevers last more than 24 hours post steroids/IVIG or in the moderate or severe presentation.[5][6]
  • Tocilizumab is also considered if fevers last more than 24 hours post steroids/IVIG or in the moderate or severe presentation.[5][6]
  • Empiric antibiotics like vancomycin, ceftriaxone, and clindamycin are given for community-acquired shock presentation until cultures are negative for 48 hours.[5][6]
Presentation Treatment
Mild Disease
  • Symptomatic Treatment
Severe Disease

Prevention of MIS-C

  • MIS-C can be prevented by reducing the risk of child exposure to COVID-19 infection.
