Firstly, I'm sorry you've developed heart problems. That sucks. I can't imagine how that feels in real life, but I can fully understand how it changes your perspective on a lot of stuff.
I should further clarify. My original comment was referring to a person who was saying, essentially, that if a person had been vaccinated, then any subsequent illness was a direct cause of the vaccine. His take was that any pre-existing condition was made worse, and the root cause of any kind of ailment was the Covid vaccine. Black & white, no room for discussion.
I can see how my comment could be misinterpreted in a number of ways. I don't subscribe to his stance, but I'm absolutely open to the increasing body of evidence of post-vaccine and post-Covid medical issues that have and continue to arise. I have a friend who was a whip-smart and highly capable gastric surgeon. She was fully vaccinated, then got Covid (positive tests), now has many symptoms of long Covid, and she's medically retired at 34. She has to have 10 minute snoozes every 30 minutes during the day. No diagnosed pre-existing conditions, she was in tip-top health.
I have absolutely no pro- or anti- agenda here, I was merely sharing some anecdotal evidence.
Most importantly, I hope you can find your way with your health stuff.
