Atherosclerosis is the underlying process that causes heart attacks, and most strokes. At SPARC, our heart attack and stroke prevention research is based on the measurement of atherosclerosis using 2-D and 3-D ultrasound. Our primary mission is stroke prevention. We measure carotid artery plaque for 3 purposes:
The known risk factors for atherosclerosis (age, being male, smoking, high blood pressure and cholesterol, and diabetes) account for less than half the risk. New risk factors for atherosclerosis such as homocysteine and Lipoprotein (a) are under investigation, but it is clear that there are many families with premature heart attacks and strokes that cannot be explained by the usual risk factors. Plaque measurement helps in identifying new genetic causes of atherosclerosis, thereby pointing the way to new therapies that will reduce the risk of heart attacks and prevent strokes.
