ClinicalTrials.gov Identifier:	NCT00114387

Purpose

The purpose of this study is to examine whether vitamin E (DL-alpha-tocopherol) supplementation will reduce the progression of early atherosclerosis in healthy individuals over 40 years of age with low-density lipoprotein (LDL) cholesterol levels greater than or equal to 130mg/dL.

Condition	Intervention	Phase
Atherosclerosis	Drug: DL-alpha-tocopherol	Phase II Phase III

Primary Outcome Measures:

Rate of change of the distal common carotid artery (CCA) far wall intima-media thickness (IMT)

Estimated Enrollment:	353
Study Start Date:	July 1996
Estimated Study Completion Date:	September 2000

Detailed Description:

The primary hypothesis to be tested is that vitamin E supplementation of 400 IU/day exerts positive arterial wall effects by reducing progression of early atherosclerosis in healthy individuals 40 years old or older without clinical evidence of cardiovascular disease (CVD). Ultrasonography will be used to measure the rate of change of the distal common carotid artery (CCA) far wall intima-media thickness (IMT). The beneficial effects of vitamin E supplementation are expected to occur with or without a change in LDL-C levels.

A total of 353 men and women will be recruited for the three-year trial. Participants will be randomized into a treatment group to receive either vitamin E (DL-alpha-tocopherol) 400 IU/day or a placebo. The ultrasound measurement of CCA IMT will be repeated every six months for two years.
