"Would be nice if there was info about any difference in the rate of heart attacks per 100,000 in the vaccinated and unvaccinated group (controlled for age group too). I don't know if they are keeping track"

They certainly try not to. Check some of my previously posted substack links. It's been and order from above to obfuscate the vaccination status of patients going in with any kind of illness now. Little intricate bureaucratic thingies implemented that make "vaccinated" people "unvaccinated" in the public record.

Some statistics, though, couldn't be hidden, like more c19 problems for vaccinated from stats that accounts "per 100k people from group x".
Also generally the heart diseases have suddenly grown to be the most serious problem in heavily vaxed countries, pushing the respiratory ailments down by a good margin.
