My brother has atreo fribulation (not sure on spelling) which doesn't cause him much trouble in general, lives a very normal life. He got the vaccine, first dose was fine, second dose nearly sent him to the ER. First issues were he woke up and "felt like death, could barely move for 4 hours". Next day his heart issue flared up worse than he says it's ever been and finally calmed down shortly before he was going to have his wife take him to the hospital.
He had covid in the summer and barely noticed it.
Anecdotal, I know. He did not report these adverse reactions. So I wouldn't consider the data to be the end-all-be-all.
But judging on how some people act in this thread I'm sure my brother having these potentially life threatening reactions will be laughed at, or I'll be called a liar.
