The cardiac risks of vaccination are knowable and are in fact known, as are the cardiac risks of COVID infection, which in unvaccinated people confers a 10-50 times higher risk (depending on the study) than vaccination without infection, and 2-15 times higher risk (depending on the study) than vaccination with subsequent infection.
If you are immune from ever getting COVID-19, yes, maybe you can consider not getting vaccinated.
But if you are not luckily encased in a bubble and might get COVID-19 some day, then you are much better off from the perspective of cardiovascular health to get vaccinated. Especially the newer bivalent booster. Lots of data coming out on it, including this summary tweet from Eric Topol on its amazing efficacy in the over 65 population
