This is what I was wondering. Maybe those that are having this heart condition had asymptmatic Covid in the past and didn't know they had it? I'm glad they are looking into it, but how can they really connect if it was the vaccine that caused it if they don't know if the person had Covid prior to the shot? And I bet this will deter more people from getting vaccinated, especially in the young adult age group that they are seeing more infections in now.
