Two-dimensional ultrasound is a widely used technique for the clinical
assessment of carotid atherosclerosis. We measured Volumes of atheros
clerotic plaques in carotid arteries in 70 patients with a newly devel
oped and tested three-dimensional ultrasound method over a period of t
welve months to determine the relation between progression or regressi
on of plaque Volume and vascular risk factors. In multiple regression
analysis of age, size, smoking, total cholesterol, HDL-cholesterol, HD
L/total cholesterol ratio, LDL-cholesterol, triglycerides, HbA1, diast
olic and systolic blood pressure, the strongest predictor of plaque pr
ogression (p<0.01) was diastolic blood pressure, diabetes came next (p
<0.05). The optimal adjustment of all risk factors showed a significan
t influence on plaque progression (r: 0.76).
