Research Standard for Covid Vaccine Myocarditis Risk
Research was done for infection but not vaccination
This represents a summary of the BIG-10 study looking for COVID-19 myocarditis in May 2021. This study was used to promote vaccines in the younger cohort based on the presumption that Covid infection would be blocked by vaccination.
The aims of this study were to estimate the prevalence of myocarditis among athletes after COVID-19 infection, to compare differences in COVID-19 myocarditis across Big Ten Universities, to evaluate the utility of different diagnostic strategies for myocarditis screening among competitive athletes, and to review timing and results of repeat CMR imaging to inform safe RTP (return to play) decisions.

Four tested modalities
Electrocardiogram (ECG) - It is a medical test that records the electrical impulses generated by the heart as it contracts and relaxes create a pattern of electrical signals, which can be detected and visualized through electrodes placed on the skin.
Echocardiogram - medical imaging test that uses ultrasound technology to create detailed images of the heart's structure and function. It allows visualization of the heart in real-time, capturing moving images of the heart's chambers, valves, and blood flow.
Serum troponin levels - troponin refers to a group of specific proteins found in cardiac muscle cells, and it is often used as a marker to diagnose and assess heart-related conditions
Cardiac magnetic resonance (CMR) - Cardiac magnetic resonance imaging (MRI) uses a powerful magnetic field and radio waves to create images of the heart's structure, function, and blood vessels. It provides highly detailed and accurate information about the heart and is a valuable tool for diagnosing and assessing a wide range of cardiac conditions.
Outcomes for COVID-19 Myocarditis
“cardiovascular testing was performed in 1597 athletes (964 men [60.4%]). Thirty-seven (including 27 men) were diagnosed with COVID-19 myocarditis (overall 2.3%; range per program, 0%-7.6%); 9 had clinical myocarditis and 28 had subclinical myocarditis. If cardiac testing was based on cardiac symptoms alone, only 5 athletes would have been detected (detected prevalence, 0.31%). Cardiac magnetic resonance imaging for all athletes yielded a 7.4-fold increase in detection of myocarditis (clinical and subclinical). Follow-up CMR imaging performed in 27 (73.0%) demonstrated resolution of T2 elevation in all (100%) and late gadolinium enhancement in 11 (40.7%).”
What is late gadolinium enhancement?
Late gadolinium enhancement (LGE) is a technique used in cardiac magnetic resonance imaging (MRI) to visualize and assess areas of scar tissue or damaged myocardium (heart muscle). It provides valuable information about the health and function of the heart, particularly after a heart attack (myocardial infarction) or in certain cardiomyopathies.
Why was this standard of research not done for Covid Vaccination?

Thank you for looking at this. Can you say what the background levels of myocarditis are in athletes that did not have Covid? With that we can better understand how much was caused by Covid and how much subclinical exists regardless of Covid and treatments.
Prominent vaccine proponent Dr. Paul Offit speculating about autoimmunity and why the COVID vaccines cause myocarditis. I thought you mind find this interesting Dr.McMillan.
