I have only heard that it is more common from online strangers, I doubt that the claim of it being more common has any truth to it. Perhaps it seems more common because of media coverage and generally more people playing sports. It would be a worthy point of discussion if there were a major uptick in heart related deaths.

The only “evidence” I’ve been shown/seen mentioned is from something like “goodsciencing.com”  They claimed to have catalogued every heart-related collapse in athletics over the last X years and try to show a huge increase post-vaccine.

I googled something like “2015 athlete collapses” and found an instance they didn’t record on the first page of google. They obviously undercounted the pre-covid years. So if you see that site brought up it’s garbage.
