Title: Covid / vaccine related heart problems - anecdotal or proven?
Post by: tackem on 22/03/2022 23:11:25

Are stories of Covid / vaccine related heart problems simply anecdotal or are there any statistics to prove or disprove this growing belief.

It appears there is evidence that myocarditis is associated with the COVID-19 RNA vaccination: https://www.bmj.com/content/375/bmj-2021-068665

The risk is still pretty low. According to that study, the average incidence rate is about 1.4 out of 100,000 people within the first 28 days of vaccination.

The risk is reportedly highest in men around 20 years - perhaps because they have a strong immune system?

One problem with analyzing individual cases is that COVID also infects heart muscle, and can cause myorcarditis or pericarditis.
- So if someone gets myocarditis after vaccination, was it caused by the vaccine, or because they caught COVID at roughly the same time?
- Or did they get myocarditis from an unrelated cause (there were many cases every year, even before COVID)
- You really need to collect a lot of cases to separate these three categories
- Until someone invents a test to distinguish between the different causes

yea, it does happen.i got an extremely irregular heart rhythm about 10days after Pfizer shot. the second shot didn't change things and normal rhythm returned slowly after several months. I received the booster in nov and my heart went crazy again to the extent I would not take another. I must emphasise no chest pain,no breathlessness and no apparent change in exercise tolerance occurred. I believe this is a case of the viral surface antigen released by the vaccine cross-reacting with some myocardial protein, similar to how streptococcal antigens can cause rheumatic heart disease.however if one has heart problems with the vaccine, I would expect similar or worse with a covid infection.i'm 70
