Doctors and scientists studying the coronavirus and COVID-19 are concluding this is not a respiratory disease, but a vascular one. That means the virus does not attach in the lungs and the airway, like the influenza virus; instead, this coronavirus attaches to blood vessels. This means any area of the body where there are smaller blood vessels — the heart, lungs, kidney, brain, and more — is at risk of long-term damage from mini-clots in those vessels (something found in autopsies of some COVID-19 victims).
The heart issues in particular — and everything we don’t know about a virus that is still only about 10 months old — has NBA team executives concerned about the long-term effects on players as they head to Orlando for the restart of the season.
Baxter Holmes of ESPN had fantastic insight on this subject, speaking to team officials for his story.
“There are unknown effects it has on lung capacity, unknown effects it has on cardiac health,” said one general manager of a team entering the NBA bubble, speaking on the condition of anonymity. “What if a 24-year-old catches it in Orlando and, in 14 days, he quarantines and is fine, but then he has these everlasting heart problems? [Or he] gets winded so easily, or he becomes a little bit too susceptible to fatigue? … These are all the unknowns.”
The NBA and the NBPA were particularly focused on the heart and cardiac concerns based on studies that found exercise while ill by people who had even a mild form of COVID-19 increased the risk of heart issues. The NBA’s director of sports medicine John DiFiori put it this way (as general advice) in the ESPN story:
“If you don’t feel well, don’t try to push through this. This is not a situation where anyone, whether you’re an athlete or not, should try to push through or minimize symptoms or try to ignore symptoms and try to push through to try to continue to work or continue to play a sport.”
What that means for players is if they test positive in the Orlando bubble they will be put on a two-week quarantine without exercise or much activity. The challenge then becomes that once said player is cleared they will have lost some conditioning and need to work out to get in shape again — they cannot just step back onto an NBA court and play. The bottom line, if a player tests positive they may be out more than only two weeks.
Ultimately, doctors know little about the long-term impacts of the disease on the body because this strain is so young — even the first people in China who had COVID-19 and recovered did so fewer than nine months ago. There are concerns about impacts on the heart and lung — not to mention other areas of the body — and far more questions than answers.
Which is why the NBA and players union want to be cautious. And why team executives are concerned.
