Clean mouthguard: Corona viruses do not die when the heat is 70 degrees

This showed that thrombosis complications occurred in almost every third corona patient. However, “only” 184 infected people were examined. The Dutch researchers described this proportion as “remarkably high”.

Scientists from the USA have also examined the blood clots more closely. According to this, the risk of thrombosis due to Covid-19 is so high that those affected “may need to be given prophylactic blood thinners”. The study by the research team around Behnood Bikdeli, a doctor from New York, was published in the specialist magazine Journal of The American College of Cardiology published.

He has seen hundreds of blood clots in his career, but never so many “abnormal extreme cases”, the doctor reports.

Coronavirus infection: why do thromboses form?

The question of why blood clots can form in Covid 19 patients has not yet been conclusively investigated. However, one explanation is that corona patients mostly have pre-existing diseases in organs such as the heart or lungs. These increase the risk of thrombosis anyway.

Another approach could be the corona virus itself. An article in the trade magazine puts this connection The Lancet near: It explains that “Sars-CoV-2” can attack and infect the inner cell layer of blood vessels and organs. This can lead to thrombosis.

One factor that could not explain the origin, but is considered to be beneficial, is the rigid lying of the patient in the intensive care unit. According to various scientists, this supports the development of blood clots.

The US researchers’ request to use blood thinners for treatment does not help all patients, says New Yorker Rzin Brosnahan AFP : Some are ineffective, others are effective. “There are too many micro clots and we don’t know exactly where they are,” said the doctor.

Conclusion: The numerous blood clots in organs of Covid 19 patients are to be examined even more intensively in the coming months. For the time being, the question of what the many thromboses are in corona sufferers has not yet been finally resolved.
