|ClinicalTrials.gov Identifier: NCT00258973|
Recruitment Status : Completed
First Posted : November 28, 2005
Last Update Posted : December 3, 2015
The purposes of this study are to determine:
- Inter-site variability in CIMT image measurement using SonoCalcTM.
- 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.
- 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.
- If CIMT measurements and plaque assessment performed in office practices lead to meaningful changes in patient and physician behavior related to cardiovascular disease prevention.
