Researchers from Germany discovered evidence suggesting that a COVID vaccine-triggered autoimmune reaction may be the cause of myocarditis in 14/15 patients.
The comprehensive analysis of endomyocardial biopsy (EMBs) from 15 patients with myocarditis was published on NIH’s PubMed, (Intramyocardial Inflammation after COVID-19 Vaccination: An Endomyocardial Biopsy-Proven Case Series).
Endomyocardial biopsy (EMB) is a procedure that percutaneously obtains small amounts of myocardial tissue for diagnostic, therapeutic, and research purposes.
“The decision to perform EMB was made by the attending physician based on the setting of unexplained heart failure and sudden onset of severe left ventricular failure,” according to the study.
There were a total of 15 patients from 11 different clinics included in this multicenter study. The attending physician suspected myocarditis following COVID-19 vaccination for all patients because of the correlation between vaccination and the start of myocarditis symptoms.
The age range of the cohort is 18-68, and 9/15 (60% of the sample) are male. All patients were Caucasian. Variations in vaccination history, symptom onset, clinical suspicion, and clinical course are widely observed in the reported group.
The table below shows the demographic information, clinical presentation, and test results of patients admitted to the hospital. “Importantly, the suspicion of myocarditis in response to vaccination against COVID-19 was expressed in all cases.”
