Blood clots can affect people of all ages, race and gender. One of the most important things you can do to prevent blood clots is to know if you are at risk. The National Blood Clot Alliance (NBCA) is dedicated to advancing the prevention, early diagnosis and successful treatment of life-threatening blood clots such as deep vein thrombosis, pulmonary embolism, and clot-provoked stroke.
