Time perspective: PROSPECTIVE

Brief summary: The purposes of this study are to determine:

1. Inter-site variability in CIMT image measurement using SonoCalcTM.
2. If non-sonographer health care professionals working in an office practice setting can be trained to follow a carotid scanning protocol that permits (a) accurate measurement of CIMT and (b) determination of plaque presence.
3. If (a) CIMT measurements and (b) determination of plaque presence by non-sonographer health care professionals are bioequivalent to those made by a core laboratory.
4. If CIMT measurements and plaque assessment performed in office practices lead to meaningful changes in patient and physician behavior related to cardiovascular disease prevention.
