Who May Participate in CREST-2?

Adult men and women who are:
  • Age 35 years and older
  • Have high-grade narrowing of at least one of their carotid arteries
  • Lack serious other medical complications.

​How Do You Know if Your Arteries are Blocked?

Two tests may be performed by your physician to determine if you have narrowing in your carotid arteries:
  • Cerebral angiography uses contrast material injected into an artery (usually in the groin) to make the vessels in the head and neck visible in x-rays. (Scroll over Figure 1 below.) Pictures are then taken and the amount of narrowing is measured. 
  • Ultrasound, or carotid Doppler, uses sound waves to measure the rate of blood flow through the artery. (Scroll over Figure 2 below.) If you have not had an ultrasound within the last 30 days and you decide to participate, you will have this test. 
FIG. 1. Cerebral Angiography creates an x-ray image of blood vessels in the head and neck.
FIG. 2. Ultrasound, or carotid Doppler, uses sound waves to measure the rate of flow through your carotid arteries.
