Which vaccination should you get with pre-existing heart conditions?

I was afraid to get vaccinated, 3 family members with in 2 days of being vaccinated had heart attacks. It has been a few months and I have not heard of anybody else having that problem. All three family members were told getting vaccinated had nothing to do with heart attacks. So I have asked 2 nurses I know if they told their patients which one to get when you have preexisting conditions. They both told me that they were not qualified to give their opinion on he vaccine. So I'm asking any of you, if you have been told by a medical professional which one is more beneficial with preexisting conditions ? Which one did you get and why? Thanks for giving me an education on these vaccines.
