A large study published this week by British scientists found that people who detected mild cases of Covid-19 in the first year of the pandemic were at a higher risk of developing blood clots than those who were not infected.
Mild Covid patients, defined as non-hospitalized patients, were 2.7 times more likely to develop blood clots. According to a study published Monday in the British Medical Journal’s HeartThey were also 10 times more likely to die than those who did not have Covid.
Scientists at Queen Mary University in London tracked 18,000 people who contracted Covid in the first year of the pandemic and compared their health status to about 34,000 who did not.
Participants were followed until they developed cardiovascular disease or died, or until the study ended in March 2021. Most of the research was conducted before the vaccine was rolled out in the UK in December 2020.
People with mild COVID-19 had a higher risk of blood clots, but patients hospitalized with the virus generally had a significantly higher risk of cardiovascular disease. The risk of cardiovascular disease for mild and severe cases was highest during his first 30 days after infection and continued thereafter.
The study found that patients hospitalized with Covid were 28 times more likely to develop blood clots, 22 times more likely to have heart failure, and 17 times more likely to have a stroke. They were 100 times more likely to die than those who did not.
The scientists said their findings underscore the importance of long-term monitoring of even people who have had mild Covid for cardiovascular disease.
“Our findings highlight an increased cardiovascular risk among previously infected individuals, which may be higher in countries with limited access to vaccines.” , which may result in higher exposure to COVID-19,” the study’s authors wrote.
