Covid-19 causes blood clots in patients

Doctors observe blood clots in patients with Covid-19, which can lead to thrombotic complications (symbol image).
In the case of coronavirus disease, there are always very serious courses, which in certain circumstances can also lead to death. Doctors have often found blood clots in those infected, the development of which has not yet been fully clarified.
The longer the coronavirus is rampant, the more information doctors and scientists can obtain about the virus and its effects. Now another phenomenon has been observed: Blood clots believed to be caused by Covid-19. Thrombosis can have serious effects.
Covid-19 patients with blood clots often with a severe course
Dr. Shari Brosnahan, who works at Langone University Hospital in New York, reports dramatic reports: “I was 40 years old in my intensive care unit who had blood clots on my fingers and it looked like they would lose them.” In one of his patients, the course was so poor that both the legs and hands no longer received adequate blood, and amputation was likely.
At the moment, the only possible explanation for the blood clot is the coronavirus. That too Broadway star Nick Cordero was in the ICU for weeks due to a corona virus infection. However, doctors were no longer able to save the 41-year-old man’s right leg and had to amputate it. He had died from a blood clot probably caused by the virus. Doctors in Europe, the United States, and China are now reporting the phenomenon of blood clots.

Blood clots cause strokes and pulmonary embolism.
Blood clots are not only dangerous for the extremities. If they occur in the lungs, brain, or heart, they can cause serious complications, such as a pulmonary embolism, a stroke, or a heart attack.
A new study was published in the Dutch journal Thrombosis Research, which analyzed thrombotic complications in patients with Covid-19. Scientists discovered that almost every third of 184 patients examined had these complications. The authors described this ratio as “remarkably high,” even if, fortunately, the extreme consequences, such as an amputation, rarely remained.
But the risk of thrombosis caused by the coronavirus should not be overlooked. The research team led by New York physician Behnood Bikdeli in the “Journal of The American College of Cardiology” also recommends that patients “be given prophylactic anticoagulants.” New York physician Behnood Bikdeli also states: “I have seen hundreds of blood clots in my career, but I have never seen so many extreme abnormal cases.”
The cause of the blood clot is still unclear.
Until now, doctors have been unable to determine why blood clots form in Covid-19. However, one explanation could be that many patients who develop the coronavirus and go through a serious course already have pre-existing heart or lung disease. There is already an increased risk of thrombosis in these infected people.
The long, stiff lie in the intensive care unit can also promote the formation of blood clots. So far, it’s clear that Covid-19 can trigger a cytokine storm. This overreaction of the immune system could lead to thrombosis.
However, since other viruses can also cause blood clots, this could also be the case with the coronavirus. The virus can infect the internal cell layer of organs and blood vessels and therefore cause bleeding disorders, as explained in an article in “The Lancet” magazine.
The micro clot problem
Intensive care doctor Shari Brosnahan confirms that heparin may help the anticoagulant in some patients. But there are also infected people for whom the remedy does not work. “There are too many micro clots and we don’t know exactly where they are,” said the doctor.
Autopsies found that the lungs of some of the people who died from lung disease were filled with small blood clots. However, this finding helps to explain another disease phenomenon with Covid-19: for many patients infected with the virus, artificial ventilation did not help to compensate for the lack of oxygen in the blood. In some Covid 19 patients, ventilation actually worsens the condition. According to Cecilia Mirant-Borde, an intensive care doctor at a military hospital in Manhattan, micro clots in the lungs could be the reason. Because the clots would block blood circulation in the lungs and thus also impede the supply of oxygen. More about this: Covid-19 does this with the lungs
