Is myocarditis hard to diagnose? if so could this be a rising cause of death in covid patients as well as vaccinated patients who are dying?

My understanding is that myocarditis is less common in the vaccinated than in the unvaccinated populations. Incidence is rare, but notable. If concerned, talk to our GP.

Answers to your questions are clearly no and no. No scientific data support your suspicions.

Not too hard too diagnose. Typically with chest pain, possibly some ECG changes, and some elevation in cardiac enzymes (a blood test). There is a risk of myocarditis with a COVID 19 infection. Some of the vaccines are associated with increased risk of myocarditis, particularly in males under age 30.
