Myocarditis

Myocarditis is a condition of inflammation of the heart muscle, and pericarditis is inflammation of the outer lining of the heart. Myopericarditis is where both occur simultaneously. In all three cases, the body’s immune system causes inflammation in response to an infection or some other trigger.

Myocarditis in Animals

Animals other than humans can suffer from myocarditis.

Myocarditis During the COVID-19 Pandemic

Myocarditis can be caused by Covid-19 infection as well as a side effect of Covid-19 Vaccination (see also myocarditis).

Florida Surgeon General Warning

Florida Department of Health sent this bulletin at 10/07/2022 06:12 PM EDT

TALLAHASSEE, Fla. – Today, State Surgeon General Dr. Joseph A. Ladapo has announced new guidance regarding mRNA vaccines. The Florida Department of Health (Department) conducted an analysis through a self-controlled case series, which is a technique originally developed to evaluate vaccine safety.

This analysis found that there is an 84% increase in the relative incidence of cardiac-related death among males 18-39 years old within 28 days following mRNA vaccination. With a high level of global immunity to COVID-19, the benefit of vaccination is likely outweighed by this abnormally high risk of cardiac-related death among men in this age group. Non-mRNA vaccines were not found to have these increased risks.

As such, the State Surgeon General recommends against males aged 18 to 39 from receiving mRNA COVID-19 vaccines. Those with preexisting cardiac conditions, such as myocarditis and pericarditis, should take particular caution when making this decision.

“Studying the safety and efficacy of any medications, including vaccines, is an important component of public health,” said Surgeon General Dr. Joseph Ladapo. “Far less attention has been paid to safety and the concerns of many individuals have been dismissed – these are important findings that should be communicated to Floridians. 2)

Guidance for mRNA COVID-19 Vaccines - October 7, 2022 Florida continues to emphasize that health care providers review all data to evaluate risks and benefits unique to each patient when determining any health care services to provide, including the administration of COVID-19 vaccines containing Messenger RNA (mRNA) which both the Pfizer - BioNTech and the Moderna vaccines utilize.

The Florida Department of Health (Department) conducted an analysis through a self-controlled case series, which is a technique originally developed to evaluate vaccine safety. This studied mortality risk following mRNA COVID-19 vaccination. This analysis found there is an 84% increase in the relative incidence of cardiac-related death among males 18-39 years old within 28 days following mRNA vaccination. Individuals with preexisting cardiac conditions, such as myocarditis and pericarditis, should take particular caution when considering vaccination and discuss with their health care provider.

As such, the Florida Department of Health has issued the following guidance 4)
