World Thrombosis Day 2023

By Ellie Nixon | 13th October 2023

Recognised on October 13th, World Thrombosis Day (WTD) focuses attention on the often overlooked and misunderstood condition of thrombosis.

With thousands of educational events in countries around the world, World Thrombosis Day and its partners place a global spotlight on blood clots as an urgent and growing health problem.

Their mission supports the World Health Assembly global target of reducing premature deaths by non-communicable disease by 25 percent by 2025, as well as the World Health Organization’s 13th General Programme of Work 2019–2023, the Montevideo Roadmap 2018-2030 on NCDs and the Political Declaration of UNGA’ Third High-level Meeting on NCDs.

What is Thrombosis?

Thrombosis is the formation of a blood clot in a blood vessel. The vessel may be any vein or artery, such as in a deep vein thrombosis (venous) or a coronary artery (arterial). Any clot that forms in a blood vessel is called a “thrombus.”

Once formed, a venous thrombus can slow or block normal blood flow, and even break loose and travel round the body through the vessels. A clot that travels to the circulation is called an embolism. Thrombosis is the often-preventable underlying pathology of heart attack, thromboembolic stroke, and venous thromboembolism (VTE), the top three cardiovascular killers.

Thrombosis is normally categorized by where it occurs in the body. The two types of thrombosis are venous and arterial, depending on whether the clot develops in the vein or an artery. Both are influenced by acquired or inherited risk factors, although the risk factors are different for each. (2)

Global Objectives - Working together to save lives

  1. Highlight the burden of disease (thrombosis in general) and highlight the need for action, specifically underscoring the unrecognized threat and serious consequences (morbidity and mortality) related to venous thromboembolism (VTE) and atrial fibrillation (AFib).
  2. Increase public awareness of the significance, risks, signs and symptoms of thrombosis, specifically VTE and AFib as an important cause of thromboembolic stroke.
  3. Empower individuals to talk with their healthcare providers about their risk for thrombosis and appropriate prevention. Empower individuals to seek immediate medical attention if they have signs and symptoms.
  4. Galvanize organizations in countries across the globe to conduct appropriate and aligned campaigns in their regions.
  5. Advocate for “systems of care” to properly prevent, diagnose and treat VTE and AFib.
