How Blood Clots Impact You

If a blood clot partially or totally blocks the blood flow in your veins or arteries, it can lead to potentially life-threatening conditions. In fact, blood clots are the underlying cause of the world’s top three cardiovascular killers: heart attack, stroke and venous thromboembolism (VTE) – a blood clot that is found most commonly in the leg or lung1



85% of all strokes are caused by blood clots2. For example, people with atrial fibrillation (AF) have an irregular heartbeat that causes turbulent blood flow and can lead to the blood clotting3. These blood clots can travel to the brain and trigger a major and often fatal stroke4Brain


Heart Attack

When the blood supply to a part of the heart is blocked by a blood clot, the heart can no longer receive oxygen and nutrients. The heart muscle cells stop working and ultimately die5Heart


Pulmonary Embolism (PE)

When part of a blood clot in the leg (commonly called a DVT) breaks off and travels to the lungs and blocks blood supply to part of the lung6. PE can be rapidly fatal7,8, so it is important to know the symptoms and seek medical attentionLung


Deep Vein Thrombosis (DVT)

A blood clot that forms in a deep vein – most often in the leg6. Symptoms of DVT such as pain, swelling and redness might be overlooked as something else, something less serious9,10Leg

Facts About Venous Blood Clots

Venous blood clots develop in a vein and are found most often in the leg6 – known as deep vein thrombosis (DVT). If all or part of the DVT breaks off and the blood clot moves to block a vessel in the lung, it is known as a pulmonary embolism (PE)6, which can be rapidly fatal7,8. But these potentially deadly blood clots can be prevented and treated

Moving Against Venous Blood Clots

A blood clot in the leg or lung can happen to anyone at any age, but it can be prevented and treated. In fact, venous blood clots – sometimes called VTE – are the third most common cardiovascular condition worldwide1. Learn more about venous blood clots below or by downloading the VTE Infographic


Identify your risk factors

It’s important to know the risk factors and that certain events or situations can provoke or trigger the formation of a blood clot. Risk factors include advancing age, temporary immobilisation including travel, major surgery or trauma, pregnancy, specific medical conditions (e.g., cancer), oestrogen use, being overweight, long period of inactivity and family history9,10


Know the signs and symptoms

Be sure to know the signs and symptoms so you can seek the appropriate medical attention right away. DVT symptoms include pain, swelling, redness of the area, dilation of the surface veins and the skin can be warm to touch9,10. PE symptoms include shortness of breath, chest pain, rapid heart rate, coughing blood and light headedness9,10


Take preventative measures

Once you are aware of your risk factors, you can take action to address each one and lower your risk of a blood clot. For example, if you will be having major surgery you can talk to your doctor about medicines for blood clot prevention or if you are immobile for an extended period, such as when travelling or even sitting at your desk, be sure to move from time to time to keep your blood flowing


Be proactive and talk to your doctor

Some people may not show symptoms, so if you think you are at risk then talk to you doctor about the treatment and prevention of venous blood clots. And if you do experience any symptoms, make sure to seek medical attention right away

People are Moving Across the Globe

Did you know that simply sitting for more than 90 minutes drops the blood circulation behind your knee by 50%, increasing the risk of DVT? This is why we are moving against thrombosis, so join us on the Time2Move tour to help raise awareness and understanding, and see how others around the globe are moving on this interactive map

A campaign called Get Britain Standing has launched to increase awareness and education of the dangers of sedentary working and prolonged sitting time, with the vision that within 20 years more than 80% of the workforce will convert between 2 – 4 hours of sitting time with standing daily at their desk.

In Scandinavia there is legislation providing guidance to employers that office workers should have a right to height adjustable desks to reduce sitting time whilst at work. Active working and sit-stand workstations deliver a compelling solution, enabling sitting with intermittent periods of standing.

The Thrombo Coach team visit the ESVS 2015 Annual Meeting and take to the streets of Porto to continue raising awareness of the Time2Move Campaign.

Commuters were invited to join local celebrity choreographer Lucky Ikeda at a dance class in Tokyo Station to learn exercises that can help to prevent VTE. The best part? The exercises were led by five robots!

Human “blood cells” took to the streets with our Thrombo Coaches to educate the public on blood clots before driving a health check-up truck throughout Park Villa Lobos and participating in the Asics Women’s Health Marathon.

A workshop was hosted inviting media across China to learn from leading professionals on the burden, risks, signs and symptoms and preventative measures of VTE. Participation included a VTE awareness quiz and “clot men” encouraging attendees to get up and move.

Alongside the Mexican Association for the Study of Hematology and the Latin-American Cooperative Group of Haemostasis and Thrombosis, Thrombo Coaches encouraged dog walkers in Espana Park to stay active and held flash mobs in subway stations to challenge commuters to take the stairs, rather than the escalator.

A photo exhibition was held in the Netherlands to educate and raise awareness of thrombosis and the importance of blood clot management.

Medical experts educated Venezuelans and healthcare professionals in hospitals across the country on the signs and symptoms of blood clots and the importance of thrombosis management.
