Covid doesn't seem to be different that the flu in this regard. Any disease that has a fever component will leave some with long lasting problems. Any disease that infects the lungs will do the same. There has been nothing indicating that covid is unique in this regard.
For example, here's a paper going over heart inflamation and the flu, going over data gathered in the last 100 years [0].
> During the Sheffield, England influenza epidemic from 1972 to 1973, the cases of 50 consecutive patients who were initially diagnosed as mild cases and were treated on an outpatient basis were followed. Transient electrocardiogram (ECG) changes were seen in 18 patients, and long-lasting changes were seen in 5 patients.
