Community COVID-19 Respiratory Illness is Not Associated with Myopericarditis

Cannot Shift Blame Away from COVID-19 Vaccination

by Peter A. McCullough, MD, MPH

The public has been confused with messaging from academia concerning myocarditis.  During 2020 there was a focus on heart inflammation with the respiratory illness with large studies attempting to “find” cases.   For example, the Big Ten college athletic league had an exhaustive program offered to >9600 students measuring cardiac troponin, and doing additional studies including MRI in the 30% of athletes who contracted the respiratory illness.[i]  After finding just a handful of suspected cases in thousands of studies and no hospitalizations and deaths, the program closed just before the students were encouraged and some later mandated undergo COVID-19 vaccination which has an FDA warning indicating the vaccines cause myocarditis.  It was a tragedy to close a costly screening program just before the REAL CAUSE of myocarditis was introduced into the colleges.  Joy et al performed a detailed prospective cohort study with troponin and multimodality cardiac imaging in healthcare workers who contracted COVID-19 and no evidence of heart damage was found.[ii]  Yet, messaging persisted in the medical community that “COVID-19 causes more myocarditis than the vaccines.”[iii]  This was based on flawed inpatient studies of acute severe COVID-19 where troponin levels are commonly elevated due to critical illness without adjudicated myocarditis.  This is very different from healthy individuals who take a vaccine and then develop chest pain, effort intolerance, ECG changes, dramatic troponin elevations, and have confirmation by MRI.  Community studies such as a recent one by Tuvali et al from Israel are far more likely to find a “signal” if it exists in the time period before vaccines were introduced.[iv]  As you can see, there was no increase in myocarditis above the very low baseline rate of those without COVID-19 in Israel.


This is reassuring since we can focus on COVID-19 vaccination as the likely determinant of myocarditis and pericarditis in 2021 and beyond.  For a wonderful teaching video regarding this paper see the YouTube by the venerable Professor John Campbell.  Tuvali et al, reviewed by Professor John Cambell So the next time a young person is seeking medical clearance to participate in sports, be sure to mention COVID-19 vaccination as part of the medical history and to prompt the doctor to evaluate, if warranted, any signs of heart damage that may have occurred.
