Myocarditis after SARS-CoV-2 infection and COVID-19 vaccination: Epidemiology, outcomes, and new perspectives<\/a><\/h4>

Conclusion:<\/h3>
Our conclusions refute several claims previously made by public health agencies and professional associations, namely the following: (1) the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and Omicron infections have caused more cases of myocarditis than the COVID-19 mRNA immunizations; (2) mRNA vaccine-induced myocarditis is typically mild, transient, and rare, with no long-term sequelae; and (3) the risk-benefit calculus favors continued use of these products despite evidence of more iatrogenic cases. We address each of these misconceptions by applying a combination of epidemiological, clinical, and immunological perspectives.\u00a0<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Case of Myocarditis, Pericarditis, and Fatal Aortic Dissection Following Covid-19 vaccination<\/a><\/h3>
Pre-Print<\/strong><\/div>
Quote:\u00a0<\/div>
“However, currently, a standard method of reporting myocarditis and cardiac adverse events, incidence rate, and follow-up findings does not exist, but gaps do exist in many current studies.<\/div>
For instance, myocarditis patients selected for research studies typically restrict the inclusion of patients who have presented with myocarditis within 7 to 14 days of vaccination, and many only include myocarditis cases that take place after the second dose.<\/div>
Yet, it has been shown that myocarditis incidence after COVID-19 vaccination is often known to take place after the first dose, and it can take place within 28 days and sometimes up to 90 days after the second dose.<\/div>
\u00a0<\/div>
We should also point out that many studies include only myocarditis participants with raised troponin levels, even though elevated troponin levels have been reported as an unreliable biomarker of myocarditis.<\/div>
\u00a0<\/div>
For instance, the pathology of the young man whose medical case we present herein shows raised myoglobulin markers without raised troponin <\/span>markers. Again, the biological markers and the sophisticated imaging techniques described above<\/span><\/div><\/div><\/div>
have revealed even subclinical cases or asymptomatic cases. Still, it is important to remember that not all cities and communities have access to this testing, and many cases will remain undetected. In the case presented herein and in the relevant data, we found that the above factors can exclude even serious myocarditis cases from research studies, and we also learned that cases may go undetected, untreated, and excluded from statistical analysis.”<\/div>

Determinants of COVID-19 vaccine-induced myocarditis<\/a><\/h4>

Conclusion:<\/h3>
COVID-19 vaccination is strongly associated with a serious adverse safety signal of myocarditis, particularly in children and young adults resulting in hospitalization and death. Further investigation into the underlying mechanisms of COVID-19 vaccine-induced myocarditis is imperative to create effective mitigation strategies and ensure the safety of COVID-19 vaccination programs across populations.<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Commentary: raised c-troponin levels as a sign of myocardial injury after COVID-19 vaccination in healthy individuals are worrying<\/a><\/h3>

Conclusions<\/h3>

The claim that the extent of myocardial injury after COVID-19 infection would be higher than after vaccination is not supported by empirical evidence and therefore wrong. We conclude that cross-national systematic observational studies should be conducted that allow a more precise estimation of the risk\u2013benefit ratio of COVID-19 mRNA vaccinations.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Conclusion: Here, we demonstrated for the first time, that in isolated cardiomyocytes, both mRNA-1273 and BNT162b2 induce specific dysfunctions that correlate pathophysiologically to cardiomyopathy. Both RyR2 impairment and sustained PKA activation may significantly increase the risk of acute cardiac events.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
