Vaccines are injected into muscle as a buffer but the vaccine certainly spreads throughout the body including the blood vessels. Unless you can point to a specific mechanism whereby a heart would be particularly vulnerable, this does not seem like a sound hypothesis. Some people worried that people getting the vaccine would suffer from Myocarditis, but it turns out that people getting covid were several times more likely to get Myocarditis than people with the mRNA vaccines. In either case, it is a rare and reversible condition. the fact that a later vaccination didn’t change your long covid suggests that the condition was established during the infection when you had active virus. The later vaccine would only protect against subsequent infections, not reverse the effects of the original infection. I’m sorry.
