I didn't get a chance to answer your question before that thread was zapped, but here goes. I am by no means an expert on myocarditis. I can look up things quickly and anything I post will be from what I just read in the literature.
One study showed 3.1% of people from 18 to 40 that were admitted into an ER for chest pains had myocarditis. I would highly speculate that most of those were older than the players on our team so the number of younger people getting myocarditis or a myocardial infarction. Another study showed that just less than half the people with those conditions actually had myocarditis, the others had MI's. That puts us at less than 1.5% but this also includes older adults. Looking at college aged youths, I would speculate that they would only be a small fraction of 1.5%. Maybe the doc's may have the actual numbers and can chime in.
The people that had the MI's often had " segmental early subendocardial defect, with corresponding segmental subendocardial or transmural delayed high enhancement in a predominantly anteroseptal or inferior vascular distribution." That's fancy for an underlying condition, maybe genetic. The ones with myocarditis had "no early defect and focal or diffuse nonsegmental nonsubendocardial delayed enhancement predominantly in an inferolateral location." A small clot may be the culprit here, that is speculation. Either way, inflammation from the virus is an issue.
I then looked up the causes for myocarditis and found "A viral infection usually causes myocarditis, but it can result from a reaction to a drug or be part of a more general inflammatory condition." Similar to myocarditis is cardiomyopathy and they are closely related. It's causes can be " viral infections (e.g., myocarditis), heart attacks, alcoholism, long-term, severe high blood pressure, genetic neuromuscular diseases (e.g., muscular dystrophies and ataxias), genetic metabolic disorders, complications from AIDS, and other reasons that have not yet been identified (idiopathic cardiomyopathy)."
As an athlete, I would be concerned that the vaccine may cause myocarditis. I think there would be a very small chance of that happening. I would also be concerned that the virus could cause it because it can. Since their age group has very little chance of death from the virus, what should they do?
