Title: Alpha Omega Trial: A Randomised, Placebo Controlled, Double Blind Intervention Study of the Effect of Low Doses of Omega-3 Fatty Acids on Cardiovascular Diseases in Patients With a History of Myocardial Infarction
Brief Summary: The Alpha Omega Trial is a randomized, placebo-controlled, double-blind dietary intervention study in 4837 postmyocardial infarction patients in the Netherlands to examine whether incidence of cardiovascular diseases during 40 months of follow-up can be prevented by low doses of omega-3 polyunsaturated fatty acids. The key objectives are:

* to examine the effect of low-dose supplementation (400 mg/day) of eicosapentaenoic acid and docosahexaenoic acid on incidence of cardiovascular diseases; and
* to examine the effect of low-dose supplementation (2 g/day) of alpha-linolenic acid on incidence of cardiovascular diseases.


Options:
A: Inclusion Criteria:

A patient may be included if he/she;

* Is aged between 18 and 55 years (both included).
* Has multiple sclerosis according to the McDonald criteria (McDonald 2001)
* Has a stable disease during the last month period prior to inclusion, and a disability equivalent to EDSS of 5.5 or less (Kurtzke 1983).
* Has shown disease activity defined as at least one relapse or at least one new MRI lesion (T1 enhancing or T2 lesion - ref. McDonald criteria) during the year prior to inclusion.
* Is prepared to and considered able to follow the protocol and to attend the planned visits during the whole study period.
* Is using adequate contraceptive methods and has negative pregnancy test results (female of childbearing potential must).
* Has given written informed consent.

Exclusion Criteria:

A patient has to be excluded if he/she;
