JAMA study has the following conclusion:  

Conclusions and Relevance  Based on passive surveillance reporting in the US, the risk of myocarditis after receiving mRNA-based COVID-19 vaccines was increased across multiple age and sex strata and was highest after the second vaccination dose in adolescent males and young men. This risk should be considered in the context of the benefits of COVID-19 vaccination.

Obviously, mRNA has a part in it.  

Even US gov body CDC said so.
