To better understand what could be causing their symptoms, the researchers conducted tests to assess their breathing patterns during exercise and typical daily procedures.
Participants were also asked to indicate patterns of fatigue in the previous half year, as well as any joint stiffness, muscle aches, sleep and concentration problems, and exercise problems.
A total of 46% developed chronic fatigue after COVID, the study found. And that’s a worrying finding, Mancini said, given that in many cases the initial COVID infection was not life-threatening or even so serious.
Her conclusion: “In principle, anyone with COVID is at risk.”
This concern is shared by Dr. Colin Franz, an assistant professor of physical medicine and rehabilitation and neurology at the Feinberg School of Medicine at Northwestern University in Chicago, who reviewed the findings.
While researchers are trying to define the problem, between 0.5% and 1% of non-hospitalized patients with COVID develop at least one symptom over long distances, he said. “Given the huge number of people who have had COVID around the world, that represents millions of people,” Franz said.
In fact, most people who develop long-term problems with COVID have never been so sick of COVID itself, he added.
“As someone who sees a few patients after COVID a week with constant worries about shortness of breath, I’m not surprised by these findings,” Franz said, “although I think many of my colleagues may be the ones who don’t see many -COVID posts. long-distance carriers. “
Franz said he was initially skeptical when he heard about persistent symptoms in patients whose COVID infection did not take them to the hospital.
“But my participation in our post-COVID clinical rehabilitation program convinced me that this is a really common problem,” he added.
The new findings were published in the December issue of JACC: Heart failure.
