One in four people worldwide die from conditions caused by  thrombosis (blood clot).  Thrombosis is a leading global cause of death and disability.   Between 60,000 to 100,000 people with DVT will die because a clot inside a deep vein in the leg, pelvis, or arm dislodges and enters one of the lungs (pulmonary embolism or PE).  Most clots are preventable.
