Award-Winning Global Campaign Unveils New Theme and Redesigned Website to Provide a Primary Resource Hub for Blood Clot Awareness 

CHAPEL HILL, NC, USA, (March 6, 2023) —World Thrombosis Day, a global awareness campaign led by the International Society on Thrombosis and Haemostasis (ISTH), announces the launch of its new campaign theme, Move Against Thrombosis, and redesigned website in recognition of the campaign’s 10th anniversary. With one in four people worldwide dying from conditions related to thrombosis, commonly known as blood clots, World Thrombosis Day focuses attention on the often-overlooked condition as an urgent and growing health problem.  

The new campaign theme of Move Against Thrombosis, which will span from 2023-2025, encourages people to get up and move to increase blood circulation, which can help lower the risk of blood clots. Reduced mobility can lead to a higher risk of blood clotting and is a significant driver in morbidity and mortality.  

“Since the inaugural World Thrombosis Day launched in 2014, the campaign has worked tirelessly to move the needle and improve blood clot awareness, education, prevention and treatment,” said Lana Castellucci, M.D., M.Sc, Chair of the World Thrombosis Day Steering Committee. “As we recognize the campaign’s 10th anniversary this year, it is exciting to see its impact, but we have more work to do. By revitalizing the campaign website and incorporating a new campaign theme that promotes movement and a healthy lifestyle, we hope to further increase awareness about blood clots and help save lives.” 

The new World Thrombosis Day website was developed to provide a more streamlined resource hub that promotes a greater understanding of blood clots among patients, survivors and their families, as well as healthcare professionals and the general public. It also offers an increased suite of educational resources in multiple languages to support the campaign’s global community of partners.  

Blood clots can form in, or travel to, the blood vessels in the arms/legs, lungs, brain, heart and other organs. The top signs and symptoms of a blood clot in the leg or deep vein thrombosis (DVT) can include pain or tenderness in the calf, swelling of the ankle or foot, redness or noticeable discoloration and/or warmth. The top signs and symptoms of a blood clot in the lungs or pulmonary embolism (PE) can include unexplained shortness of breath, rapid breathing, chest pain, rapid heart rate and/or light-headedness or passing out.
