Brief Summary
The study was actuated to evaluate the effects of a 3-year intervention with diet and/or very long chain omega-3 (VLC n-3 PUFA), in a randomized 2x2 factorial design on the progression of atherosclerosis in a high risk population. A total of 563 elderly men were included and randomized to receive usual care and VLC n-3 placebo capsules (control group), dietary advice and VLC n-3 placebo capsules, usual care and VLC n-3 capsules, and finally both VLC n-3 capsules and dietary advice. The evaluation of atherosclerosis were i) ultrasound measurement of carotid intima media thickening ii) pulse wave propagation time iii) circulating biomarkers of atherosclerosis.
