Thrombosis after coronavirus. New arrangements. The risk increases dramatically

COVID-19 is not only the disease itself, but also a variety of complications. Some of them concern inflammation and blood clotting. According to research conducted by Swedish scientists, coronavirus infection is associated with a 33-fold increased risk of pulmonary embolism, while the risk of developing deep vein thrombosis increases five-fold. Importantly, the risk of these complications persists for several months after the infection.

1. Doctors have been talking for a long time that after the coronavirus has passed through, the risk of blood clots increases
2. Now it turns out that there is a danger of pulmonary embolism – compared to people who have not had COVID-19 infection behind them – increases up to 33 times
3. Healers are at risk for up to six months after they recover

COVID-19 and blood clots

The issue of pulmonary embolism and thrombosis in the wider consciousness arose during the coronavirus pandemic. These conditions have become famous because of the alleged side effects of the COVID-19 vaccination, especially with AstraZeneca. Virologists and physicians, however, pointed out that such incidents were marginal, and that a much greater risk of blood clots occurs after coronavirus infection.

This danger is really serious. This is confirmed by the latest research by Swedish scientists, just published in the British Medical Journal. They compared the incidence of disease and deaths from blood clots during the pandemic with the 2018-2019 period.

They also commented on the risk of blood clots following vaccinations. “The level of complications from COVID-19 is much stronger and lasts much longer than what can happen after vaccination,” said Dr. Frederick Ho, a public health expert at Glasgow University who was not involved in the study. “Even people with mild symptoms of the coronavirus who do not require hospitalization have an increased risk of developing a blood clot,” he added to The Guardian.

While previous studies had shown that COVID-19 infection was associated with a risk of thrombosis, it was not known how long this risk lasted and whether this risk also existed in people who had mild disease.

The risk of pulmonary embolism is 33 times higher

To address these concerns, Dr. Anne-Marie Fors Connolly, a microbiology specialist at Umeå University in Sweden, and her team measured the risk of deep vein thrombosis, pulmonary embolism and various types of bleeding, including gastrointestinal bleeding or rupture of a blood vessel in the brain. One million people with confirmed COVID-19 infection in the period from February 2020 to May 2021 and 4 million people who did not suffer from coronavirus took a closer look.

As it turned out? After COVID-19 infection, the risk of pulmonary embolism – compared to healthy people – is 33 times higher. The risk of deep vein thrombosis increases fivefold and the risk of haemorrhage doubled.

It was also calculated how long this threat lasts. In the case of pulmonary embolism, the risk of occurrence persisted even six months after infection, when it comes to bleeding – two months, and with deep vein thrombosis, healers were at risk for three months.

And although the risk was greater, the more severe the course of COVID-19, even in the case of a mild course, the risk of developing deep vein thrombosis was three times higher than in people who did not have the disease. With a pulmonary embolism, the danger increased sevenfold.

It is very important to be aware of the risks

“A pulmonary embolism can be fatal, so it’s important to be aware of the risks,” Connolly said. – If you suddenly feel out of breath and it does not go away, and you have been infected with the coronavirus, then you should seek help from a doctor, because this increased risk may persist for up to six months – she added.

‘Our findings highlight the need for thromboprophylaxis and preventive treatment to avoid thrombotic events, especially in high-risk patients. They also show the importance of vaccination against COVID-19, she concluded.

The results of these studies are all the more important as many European countries have recently experienced successive waves of the pandemic. In Great Britain, the Omikron variant caused two disease peaks – the January sub-variant BA.1 and the March sub-variant BA.2. Dr. Ho emphasizes that thanks to vaccines, it was possible to avoid a large number of severe cases, but even light courses should arouse vigilance.

Despite the possibility of new COVID-19 variants emerging, most governments are lifting restrictions and talking about how to continue living with the coronavirus. This study shows that we should pay attention to possible complications even after a mild infection, especially with blood clots, he says.
