> A German study found that even asymptomatic COVID patients have inflammation and damage to heart tissue that’s more than what you’d expect to see. We don’t know whether this will heal or affect the heart long term.

Are you referring to this study[0] and possibly this article[1]?

(In my experience, telling people to “do research” instead of giving them links to primary sources isn’t great if you want to educate people or have a high quality discussion.)
