Every coronavirus patient who dies has ‘very clear’ signs of blood clotting, top scientists claims


EVERY coronavirus patient who has died has “very clear” signs of blood clotting, scientists have revealed.

Results from a UK study showed that all Covid-19 patients had a form of thrombosis.

While scientists are clear the blood clots aren’t the main cause of death in each case, the findings support previous research that suggests the virus causes vascular issues.

Infectious disease specialist at Imperial College London Professor Graham Cooke looked at data from post-mortems of patients who died from the virus.

So far in the UK over 44,000 people have died from the virus and the new research could help determine how patients are treated.

During the pandemic various drugs have been trialled on patients.

It’s important to note Covid is a multi-system disease

When blood clots emerged as a complication blood thinners, designed to stop clots were also trialled.

Speaking on a webinar for the Royal Society of Medicine yesterday, Professor Cooke said while there is an element of chance for each patient, blood clots appear to be an important part of the virus.

“We’ve seen patients who have coronary thrombosis and vascular thrombosis.

“So it does appear to be a very important part of the disease and we see that in terms of activation of the coagulation system.”

 

Coronary thrombosis is a blood clot in a heart vessel and vascular thrombosis is a blood clot in a vein generally.

He added that a hypercoagulable state occurs in people who have the virus.

This is when large blood clots form and can be part of disorders that are triggered by various medications.

This can lead to clots in various parts of the body which raises the risk of strokes.

He added: “It’s important to note Covid is a multi-system disease.

“I think one of the features that seems to separate it from other severe viral diseases is this more hypercoagulable state that seems to be associated with later disease.”

What are a blood clot’s symptoms and signs?

There are two types of blood clot. When a clot occurs in an artery, it’s called an arterial clot.

This can lead to a heart attack or stroke.

A blood clot in a vein is called a venous clot, with the most serious type being deep vein thrombosis (DVT).

These clots may build up more slowly over time, but can still be life-threatening.

According to Stop The Clot, signs of a blood clot in the leg or arm include:

  • pain or tenderness
  • swelling
  • skin that is warm to the touch
  • redness or discoloration of the skin

In May, one expert told the BBC that around 30 per cent of Covid patients experienced blood clots.

Professor Roopen Arya, from King’s College London said “thrombosis is a major problem”.

Research published in The Lancet last month also revealed that patients have been experiencing blood clots.

It found that blood clots from the virus are not just present in the lungs, but also in every other organ.

The research found clots in the lungs, kidneys and the heart.

In the UK around 62 per cent of people who have been hospitalised with Covid-19 suffer a stroke.

Experts are now investigating whether anti-blood clotting therapies could improve the outcome for hospitalised patients.

The British Heart Foundation previously launched a trial of TRV027.

This is a medication which helps maintain a healthy balance of hormones that regulate the consistency of blood.

This is usually done by ACE-2 receptors which are also the gateway where the coronavirus enters human cells.

TRV027 has been test for heart failure and regulates the hormones that thicken blood.
