The Daily Orange: How is myocarditis linked to COVID-19 and what are the concerns with it?
Dr. Michael Ackerman: There are thousands of diagnoses of myocarditis in the United States each year before COVID. It’s a big deal. It’s the third-leading cause of sudden death in young people. Each year, there will be about 50 to 100 athletes from Little League to (the) professional level who will die suddenly. Of those, five to 10 of them will have died from myocarditis. We know what causes this inflammation of the heart muscle, which can lead to weakening of the heart muscle and heart failure.
D.O.: Are there any other viruses that can cause myocarditis?
M.A.: Yes, there are. Long before coronavirus, there are over 20 viruses that have been implicated with the ability for this kind of heart damage that we call myocarditis. We know that almost half, around 40% to 50%, of all cardiac transplant recipients require transplants because of the damage done by myocarditis. It is a very important entity but it is one that has been around long before coronavirus. This virus is yet another virus with the capability of infecting the heart muscle and potentially damaging the heart muscle. It’s created even more anxiety during this COVID-19 pandemic.
D.O.: How does this apply to young and healthy athletes who don’t have pre-existing conditions?
M.A.: For those individuals who are asymptomatic or minimally symptomatic, this myocarditis thing is a non-issue. That’s because the virus hasn’t reached or done any damage to that viral infected person. It’s a very small number of otherwise healthy young people where the viral infection of SARS-CoV-2 is going to reach the heart, penetrate the heart, or do any measurable damage. Myocarditis taking center stage with athletes and discussing athletes risk is probably a bit overstated.
