Paxlovid

Pathologists autopsied 74 people who had lived with COVID for at least 60 days before they died. In 11, the virus was still replicating inside the heart, and those 11 were far more likely to have died with the chest pain, palpitations, and breathlessness of cardiac long COVID: 82% versus 37%.

The finding is a conference abstract, not a published paper. A physician in the thread flagged the catch: the same theory was already tested with extended Paxlovid in real long COVID trials, and both came back negative.
