Blood clots: five reasons they may happen

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.

 The Most Important Things To Know About Blood Clots

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.

 What To Know About The Blood Clot Risks Associated With The Johnson & Johnson Vaccine

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

 When a Cramp Is Actually a Clot

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.

A point-of-care global thrombosis test measuring occlusion time and endogenous lysis time may indicate thrombotic status

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

A rare clotting disorder may cloud the world’s hopes for AstraZeneca’s COVID-19 vaccine

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.

Open Your Eyes to Thrombosis

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.

The Blood-Clot Problem Is Multiplying

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

Thrombosis: The Hidden Risks and What Cancer Caregivers Need to Know

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.

Triggers, targets and treatments for thrombosis

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.

Understand Your Risk for Excessive Blood Clotting

Many factors can lead to excessive blood clotting, leading to limited or blocked blood flow.
