Spike Protein (mRNA) Myocarditis Shows Evidence of Persistent Fibrosis: Further Understanding Sudden Cardiac Deaths: Dangers of Reexposures
A recent case report documents a healthy 30‑year‑old male who developed myocarditis three days after his second Pfizer mRNA COVID‑19 shot. Cardiac magnetic resonance (CMR) imaging performed eight weeks later revealed mid‑to‑epicardial lateral wall fibrosis, which persisted, though partially resolved, at a five‑month follow‑up despite normalized symptoms and biomarkers. The author argues that such persistent fibrosis creates an arrhythmogenic substrate that can lead to ventricular tachycardia and sudden cardiac death. The post cites broader studies showing one‑third of myocarditis patients progress to chronic disease and highlights recurrence risks and exercise‑related mortality.
