A Public Health Crisis...

Almost 300,000 Americans die each year from blood clots in the veins. Most of these lives could have been saved if more patients and health professionals had known about the risks, symptoms and treatments.

That’s why NATT is leading the fight to spread the word.

The National Alliance for Thrombosis and Thrombophilia (NATT) is a nationwide alliance of patients and medical professionals committed to preventing and treating health problems caused by blood clots. We promote awareness, early diagnosis and optimal treatment through research, education, support and advocacy. Whether you are a patient, family member or medical professional, NATT is your “go-to” resource for information and breaking news on:

The Numbers are Staggering

The good news is that positive lifestyle choices and optimal treatment in high-risk situations can save lives and prevent blood clots in a significant number of cases…

However, the bad news is that only 50% of those with DVT have symptoms, making this “Silent Killer” extremely difficult to diagnose. This is compounded by the fact that 74% of Americans have no knowledge about DVT, its symptoms or risk factors.

This is why raising awareness is critical. The National Alliance for Thrombosis and Thrombophilia (NATT) is working to prevent, diagnose and treat thrombosis and thrombophilia through education, research, support and advocacy.
