Right now long term impact is unknown, which can be scary. I'd imagine that some people will have long term health issues, but at what rate and severity is unknown so don't act like this is a fact.
Initial studies point to potential lingering heart and cardiovascular-related issues, even among those who have "recovered".
"One study examined the cardiac MRIs of 100 people who had recovered from Covid-19 and compared them to heart images from 100 people who were similar but not infected with the virus. Their average age was 49 and two-thirds of the patients had recovered at home. More than two months later, infected patients were more likely to have troubling cardiac signs than people in the control group: 78 patients showed structural changes to their hearts, 76 had evidence of a biomarker signaling cardiac injury typically found after a heart attack, and 60 had signs of inflammation."
"“These are two studies that both suggest that being infected with Covid-19 carries a high likelihood of having some involvement of the heart. If not answering questions, [they] prompt important questions about what the cardiac aftermath is,” said Matthew Tomey, a cardiologist and assistant professor of medicine at the Icahn School of Medicine at Mount Sinai Health System in New York. He was not involved in either study.
“The question now is how long these changes persist,” he added. “Are these going to become chronic effects upon the heart or are these — we hope — temporary effects on cardiac function that will gradually improve over time?”
Since the pandemic began, people with underlying cardiovascular problems such as high blood pressure, coronary artery disease, or heart failure have been known to be at higher risk for infection and death. The connection between Covid-19 and blood clots emerged later, after doctors began connecting the pulmonary embolisms, strokes, and heart attacks they were seeing to the virus."
This makes sense in relation to another recent study out of Oak Ridge that found blood vessel problems are what is causing a lot of deaths (clots, etc.) - also points to potential therapeutics.
