FWIW, I wasn't suggesting that any increase in risk of heart failure wasn't due to coronavirus, just why there was an increase in it happening in a football stadium rather than having it dealt with at the doctors or hospital when the first signs appeared. Looks like that thought is backed up by what you posted then?
