Cite to a source saying heart issues are up in the population at large (which of course includes the Covid vaccinated)?
I haven’t seen any.
Now that Covid 'vaccines' have sent the numbers for death, heart issues, paralysis, blood clots etc. off the charts (hundreds or thousands of times higher than all other vaccines), the CDC has created a fake safety threshold just for Covid 'vaccines' which cannot be crossed mathematically, this way no matter how many people die or are disabled by the Covid gene therapy shots, the CDC will still claim they are safe because the case counts didn't surpass the mathematically impossible safety threshold.
The safety signal is VAERS, by design, not your query about general population.
