University of Wisconsin, Madison
ClinicalTrials.gov Identifier:
NCT00258973
First received: November 23, 2005
Last updated: December 11, 2007
Last verified: December 2007
  Purpose

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.
