James Cintolo Substack | Jan. 26, 2023

Three days after a 2nd dose of Pfizer’s COVID vaccine, a previously healthy 17-year-old male presented to ED with nausea, vomiting, no initial chest pain, or heart murmur.

  1. Blood work revealed:
  2. Elevated troponin 10.4 ng/mL (norm <0.04) which suggested cardiac damage.
  3. Elevated NT-proBNP 205 pg/mL (norm <125).

Electrocardiogram + echocardiogram normal. Patient was admitted to pediatric ICU for likely vaccine-associated myocarditis (C-VAM).

Shortly after, MRI of child revealed late gadolinium enhancement near basal, mid + apical inferior lateral walls and into lower basal wall of left ventricle which indicated fibrosis (scaring) of the heart.
