There’s been a lot of concern in recent days about blood clots, particularly after reports from Germany of people developing cerebral vein thrombosis – a blood clot in the brain – after receiving the Oxford/AstraZeneca vaccine. Other European countries have raised concerns about potentially increased risks of pulmonary embolisms and deep-vein thrombosis following vaccination.
We know that thrombosis—clot formation within a blood vessel anywhere in the body—causes 1 in 4 deaths globally. The number one killer is a heart attacks, when a blood clot develops in a coronary artery, which brings blood to the heart. Strokes occur when a clot occurs in the blood vessels supplying oxygen to the brain.
Deep vein thrombosis (DVT) and pulmonary embolism (PE) are less common, occurring in about 1 out of 1,000 people in the population every year.
We know that these clots are an immune phenomenon, which means that they don't occur right after the shot. So if you get the shot and the next day you feel crummy, that's actually probably normal. But in the four to 20 days after a shot, whether it's AstraZeneca or Johnson & Johnson, if you start getting severe symptoms - so I mean a headache that doesn't go away, difficulties with your vision that are really interfering with your function, terrible chest pain, shortness of breath, swelling in a limb - these are symptoms that you would notice
Deep-vein thrombosis is often mistaken by both patients and doctors for something else. I was suspicious of what I thought was a runner's cramp, and got lucky.
Much research to identify clinically useful molecular biomarkers that reflect overall thrombotic status has been performed over the last few decades. One of the most probable molecular biomarkers appears to be D-dimer, but this lacks specificity, with poor predictive value in arterial thrombosis
Scientists are now scrambling to understand how big that subset is and who’s in it. So far, most cases have been observed in women under age 65. But that could be because of the vaccinated population: Many countries initially used AstraZeneca only in people younger than 65 because early clinical trials included few older recipients.
Thrombosis does not discriminate. Clots can affect anyone regardless of location, age, ethnicity or race. The most important thing you can do to protect yourself from a life-threatening blood clot is to learn if you are at risk. Know the signs and symptoms and contact your health care professional immediately if needed.
For weeks, Americans looked on as other countries grappled with case reports of rare, sometimes fatal blood abnormalities among those who had received the AstraZeneca vaccine against COVID-19. That vaccine has not yet been authorized by the FDA, so restrictions on its use throughout Europe did not get that much attention in the United States. But Americans experienced a rude awakening this week when public-health officials called for a pause on the use of the Johnson & Johnson vaccine
How taking a road trip set the stage for one woman’s journey with deadly vein clots — and what you can learn from it.
Thrombosis — the formation of blood clots in a vein or artery — can affect anyone. But cancer patients are at higher risk of thrombosis than the general population, so caregivers should be particularly aware. The most common type of thrombosis in cancer patients is deep-vein thrombosis (DVT), which occurs when a clot forms in a vein deep inside the body, usually veins in the leg or arm.
Thrombosis — localized clotting of the blood — can occur in the arterial or the venous circulation and has a major medical impact. Acute arterial thrombosis is the proximal cause of most cases of myocardial infarction (heart attack) and of about 80% of strokes, collectively the most common cause of death in the developed world. Venous thromboembolism is the third leading cause of cardiovascular-associated death.
Many factors can lead to excessive blood clotting, leading to limited or blocked blood flow.
Thromboses - blood clots that form in the circulation - are easily the biggest single killer of British men and women. They affects people of all ages, races and ethnicities. Most strokes and heart attacks are caused by thromboses forming in the arteries supplying the heart or brain. But clots in the veins can be just as lethal, particularly when part of the clot breaks off and travels around the circulation and lodges in the lungs.

The goal of TA is to provide impartial health information to Australians who require thrombosis prevention. It incorporates basic information on the circumstances of thrombosis, and real life stories from patients and their families who have experienced thrombosis or related conditions.
Thrombotic vascular disease, which encompasses myocardial ischemia, stroke, peripheral arterial disease, and venous thromboembolism, represents the single greatest risk to the health of Canadians.
By bringing evidence-based primary and secondary prevention strategies to Canadian clinicians, the human and economic burden of vascular disease will be reduced.
Thrombosis Research was established in 1972 and is an international journal with a goal of rapid dissemination of new information on thrombosis, hemostasis, and vascular biology to advance science and clinical care.
Thrombosis UK is a charity working to improve understanding & awareness of life-threatening blood clots (thrombosis), often known as a DVT (deep vein thrombosis) and PE (pulmonary embolism). We want everyone to #KnowThrombosis
Celebrated year round, World Thrombosis Day (WTD) is recognized on 13 October. WTD focuses attention on the often overlooked and misunderstood disease of thrombosis.
Topics of particular interest include the diagnosis of arterial and venous thrombosis, new antithrombotic treatments, new developments in the understanding, diagnosis and treatments of atherosclerotic vessel disease, relations between haemostasis and vascular disease, hypertension, diabetes, immunology and obesity.
The risk factors for developing a venous clot are different from those for an arterial clot, and people at risk for getting one are not necessarily at risk for getting the other. Different risk factors or events can cause unnatural clotting; however, each factor may initiate clotting in a different way.
Arterial thrombosis usually affects people whose arteries are clogged with fatty deposits. This is known as atherosclerosis.
