There is no doubt that we have seen vascular damage in COVID patients. I am not claiming the vascular damage thing doesnt happen.
The current body of studies is enough to make one wonder about it and want to investigate it. The body of evidence is far too early however to state it as fact, thats all, or much about it.
My guess, the vascular damage is real, but only occurs in special cases (such as having specific bad genes, or pre-existing damage) or in particularly severe infections. But in the overwhelming majority of minor infections in healthy people I suspect it does not lasting cardiovascular damage.
It would explain a lot of what is being seen in the body of literature IMO.
Regardless I do suspect it is a real element of this virus, just one that isnt a significant concern in the less severe and healthier cases.
