Ultrasound test may identify people at high risk of Stroke.
ULTRASOUND TEST MAY IDENTIFY PEOPLE AT HIGH RISK OF STROKE. A simple ultrasound test may soon be used to identify people who are at high risk of stroke because of a condition called asymptomatic carotid stenosis (ACS). ACS is a narrowing of the carotid artery in the neck. The study, published in the August 17, 2011 online issue of the journal Neurology, followed the health of 435 ACS patients for two years who underwent ultrasound of the carotid artery and blood vessels in the brain. The procedure determines the presence of blood clots or echolucent plaque, which contains a high level of fat. People with echolucent plaque in their carotid artery were six times more likely to have a stroke than those without plaque. Those who had both plaque and blood clots were 10 times more likely to suffer a stroke. "This method," say the authors, "identified a high-risk group with an annual stroke risk of nine percent and a low risk of less than one percent."
