Consequences of COVID-19: what research has shown
A recent study by scientists analyzing UK Biobank data revealed alarming trends. The study included data from more than 11,000 people who tested positive for COVID-19 in 2020, before vaccines were available. These results were compared with information from more than 222 thousand people who did not have coronavirus during the same period.
The analysis showed that those who had recovered from COVID-19 had twice the risk of serious illnesses such as heart attacks and strokes, and these cases were often fatal.
However, the key finding was that the increased risks did not disappear over time. The researchers noted that, contrary to expectations, the long-term impact of COVID-19 on cardiovascular health persists for at least three years after recovery.
“There is no evidence of a risk reduction… This is one of the most unexpected and interesting findings,” said the study’s lead author, director of the Department of Cardiovascular and Metabolic Sciences at the Cleveland Clinic (USA).
Dr. Patricia Best, a cardiologist at the Mayo Clinic in Minnesota, who was not involved in the study, commented on the results. He stressed that infections tend to temporarily increase the risk of heart attacks, but that risk usually decreases soon after recovery. However, COVID-19 may act differently because its effect on the body is significantly different from other infections.
Possible explanations
Scientists have not yet reached a consensus on why the coronavirus causes such long-lasting effects on the cardiovascular system. COVID-19 likely causes damage to the walls of arteries and blood vessels that manifests over time, according to Hooman Allaia, a professor of biochemistry and molecular genetics at the University of Southern California.
Researchers suggest that the coronavirus may “destabilize” plaque in arteries, making them more susceptible to breaking down, increasing the risk of blood clots. Some scientists also believe that a gene associated with blood type may play a role in the increased risk of heart attacks and strokes after COVID-19, although the exact mechanism is still unclear.
