ABOUT STROKE*
- Stroke is the number 3 cause of death in the United States.
- Stroke is the leading cause of serious, long-term disability in the US. Between 15 and 30 percent of stroke survivors are permanently disabled. Three months after onset, 20 percent still require institutional care. Approximately 50 to 70% of survivors regain functional independence.
- Total blockage of the middle cerebral artery, the primary target for interventional stroke therapy, leads to a 43% death rate in one month if blood flow cannot be reestablished. The majority of survivors are severely disabled**
- In 2003, stroke related medical costs in the US will exceed $50 billion.
- 700,000 people will experience a stroke this year. Of these, about 500,000 are new strokes and 200,000 are recurrent.
- 88 percent of strokes are ischemic (meaning caused by blood clots or other blockages of arteries).
5-10 percent of strokes are caused by atherosclerotic disease, the same disease that causes heart attacks.

ABOUT THE REGISTRIES
- Interventional stroke therapy, a new treatment approach, may provide a revolutionary means to treat acute stroke. Data from interventional stroke treatment centers are being collected in the INterventional Stroke Therapy Outcomes Registry™ (INSTOR™) to help track short- and long-term benefits of this treatment.
- Intracranial angioplasty and stenting are used to treat atherosclerotic disease in the brain (intracranial). The INTRacranial Angioplasty and STenting Outcomes Registry™ (INTRASTOR™) will collect evidence to determine if this procedure will result in the prevention of stroke much like angioplasty and stenting in the coronary vessels has been demonstrated to prevent heart attacks.

|
INSTOR™ AND INTRASTOR™ are sponsored, supported, and managed by the NeuroVascular Research Foundation, a private, non-profit foundation formed exclusively for charitable and scientific purposes to study acute ischemic stroke treatment and stroke prevention, and to advance the science of such treatments for the benefit of the public health.
