Cardiovascular risk factors have utility in risk prediction but have limitations in predicting individual risk. Identifying an individual's risk remains a challenge. Emerging technologies such as carotid artery ultrasonography and measures of carotid intima-media thickness (CIMT) may be useful in identifying the susceptible patient who may benefit from more aggressive preventive therapy. This screening test is noninvasive, reproducible, inexpensive, and radiation-free. Recent data have improved our understanding of the application of CIMT as a screening tool for cardiovascular disease. CIMT measurement may place an individual into a higher- or lower-risk category, allowing for appropriate institution of preventive strategies.
