This study aims to explore whether the increased supply of dietary plant sterols and plant stanols have any influence on serum levels of phytosterols and on consistency of carotid atheromatous plaques.

Primary Outcome Measures:
  • Sterols in serum and carotid plaques at the operation [ Time Frame: at operation and one month after operation ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 30
Study Start Date: May 2006
Study Completion Date: December 2009
Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1
A group of subjects consuming daily 2 grams of plant stanols 4-6 weeks before the operation
Dietary Supplement: Plant Stanol
Plant stanols in margarines daily 2 grams
Active Comparator: 2
A group of patients consuming daily 2 grams of plant sterols 4-6 weeks before the operation
Dietary Supplement: Plant Sterol
Plant sterols in margarines daily 2 grams

Detailed Description:

This is a double-blind randomized study. The study population will consist of 30 consecutive patients who will undergo an elective carotid endarterectomy due to a tight asymptomatic stenosis. The patients will be randomized into two groups consuming either plant sterol (2g/day) or plant stanol (2g/day) spreads for two to six weeks, until the operation. Serum lipids, lipoproteins and sterols will be analyzed at the randomization, before the operation and one month after the operation. The carotid arteries will be examined for their composition of sterols.

This study gives new information concerning the relationship between dietary consumption of plant sterols and stanols and the sterol composition of the carotid plaques.
