The bhf article you linked explicitly states that there is no reason to believe that vaccine spikes behave the same way, and that getting vaccinated is the best way to avoid the spike-caused heart damage.
"This research only looked at the spike protein found on virus cells."
The impression is that, since they did not look at the spike protein from vaccines, then that is the reason there is indeed no evidence of this from vaccines, since there was no study on that. Sounds like there should be a study.
