COVID-19 linked to increased risk of blood clots months later, study finds
A new study out of Sweden has found that those who contract COVID-19 have an increased risk of certain types of blood clots, which can be fatal, up to six months after infection.
The observational study, published Thursday in the British Medical Journal, reports an increased risk of deep vein thrombosis, a blood clot in the leg, up to three months after COVID-19 infection; pulmonary embolism, a blood clot in the lung, up to six months later and a "bleeding event" up to two months.
According to researchers from Umea University, these events were higher in patients with underlying health conditions and those with more severe COVID-19.
Researchers also found there were more blood clot-related events reported during the first pandemic wave, compared with the second and third waves. However, they note this could be due to improvements in treatment and vaccine coverage in older patients following the pandemic's first wave.
The study's authors say the findings suggest that COVID-19 is an "independent risk factor" for blood clots and bleeding.
Researchers say the results highlight the importance of using medical treatments such as blood thinners to prevent the development of thrombosis amid the pandemic. Such treatment is known as thromboprophylaxis.
"Our findings arguably support thromboprophylaxis to avoid thrombotic events, especially for high risk patients, and strengthen the importance of vaccination against COVID-19," the study's authors wrote.
While a separate study published in August found that blood clots can also occur after COVID-19 vaccination, experts say the risk is much smaller compared to blood clot risk from infection.
Previous data has shown that COVID-19 increases the risk of serious blood clots, known as venous thromboembolism or VTE, but there has been little evidence according to researchers on the length of time this risk is increased.
To analyze the risk of deep vein thrombosis, pulmonary embolism and bleeding, such as gastrointestinal bleeding or a burst blood vessel in the brain, after COVID-19 infection, researchers looked at more than one million people with confirmed infection between February 2020 and May 2021 using national registries in Sweden.
According to the study, this was then compared to the data for more than four million people without COVID-19.
Researchers analyzed the risk of blood clots during the period after a person developed COVID-19 symptoms, compared to before they tested positive and long after signs of the virus had disappeared.
The study found a fivefold increase in the risk of developing deep vein thrombosis, a 33-fold increase in the risk of a pulmonary embolism, and a nearly twofold increase in risk for a bleeding event in the 30 days following infection.
Although the risks were highest in patients with more severe illness, those with mild COVID-19 not requiring hos
