My brother passed away at 35 from an undiagnosed heart condition. He was in incredible physical shape and had run a half-marathon a few weeks earlier. He had never smoked, he drank moderately and he was a vegetarian. He had no history of any kind of heart problems (or any serious medical problems, in fact), but one day he felt dizzy and had trouble staying upright, so he took a sick day from work, took a nap and never woke up. This was in 2017.
It's certainly rare, but young fit people do have heart problems. You can't conclude that this had anything to do with the vaccine, this is not how science works. Certainly the long-term health effects of the vaccines should be studied, but bandying about these kinds of anecdotes is dangerous: it's the same kind of thing that has (wrongly!) convinced so many people that vaccines cause autism.
By the way, this is not to minimize what you went through, I cannot imagine how scary or painful it must've been. I hope you will have a strong path to recovery, and I wish you all the best.
