On the contrary, this does not seem to be distinct with SARS-CoV-2. The other endemic coronaviruses (which cause pneumonia more rarely, and are typically just called 'common colds') also produce very similar 'long covid' effects in similarly tiny slices of the population.
Search your favorite repository of scientific literature for "{hku1|229e|oc43|nl63} cardiovascular" - you'll be amazed at how well documented, and yet poorly understood, this phenomenon is. There appears to be less literature for 229e, but pretty convincing for the other 3.
difference here is a lot of people with mild covid (no pneumonia) are getting lingering neurological or cardiac issues (or both)
