Noninvasive ultrasound imaging of carotid intima-media thickness (IMT) has been recommended for patients at intermediate risk cardiovascular disease to improve stratification.However, the utility this test in clinical practice and its effect on ensuing management during primary prevention remain unclear.We investigated common IMT total atherosclerotic plaque area (CPA) measurement stratification 95 (Framingham score 6 -19%).Subjects were re-stratified low, intermediate, or high based upon results (low Ͻ 0.80 mm, CPAϭ0 mm 2 ; -0.99 CPA 0.01-12 ϭ 1.0 Ͼ 12.0 ).Patients also 25 th 75 percentile values from our laboratory 0.60 -0.95 0.01-24 0.95 24.0 ).The average Framingham was 10.2 Ϯ 3.6% hard events within 10 years.Mean 0.82 0.03 18.8 3.8 , respectively.After testing, 44% 45% stratified as low risk, while 22% 40% elevated (Figure 1).Using threshold derived laboratory, 28% low-risk, 35% 27% identified risk.Risk altered Ն63% by both tests using either criteria.Carotid atherosclerosis screening adults could lead alterations subsequent majority patients.
