NCT01422317

Brief Summary

The object of this study was to evaluate the effect of a high-dose ethylester concentrate of of n-3 fatty acids administered early after an acute myocardial infarction on subsequent cardiac events and serum lipids.The second purpose of this study was to assess the impact of high-dose n-3 fatty acids on several markers of coagulation, inflammation, endothelial dysfunction and lipid peroxidation. Re-investigation was intended after a prolonged wash-out-period.

Outcome Measures

Primary Outcomes (1)

  • Fatal and non-fatal cardiac events

    Cardiac events were defined as cardiac death, resuscitation, recurrent myocardial infarction (MI) and unstable angina pectoris, presented as single or combined cardiac events. Revascularizations and death from other causes were also recorded.

    2 years

Secondary Outcomes (5)

  • Serum lipids

    One year

  • Inflammation markers

    One year

  • Coagulation markers

    One year

  • Endothelial dysfunction

    One year

  • Oxidative stress

Study Arms (2)

n-3 fatty acids

EXPERIMENTAL

Two gelatine capsules of Omacor-R (Pronova AS, Oslo) twice a day, each capsule containing eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) as ethylesters, in the average ratio of EPA to DHA of 1:2. Alpha-Tocopherol (4 mg) was added to each capsule.

Drug: EPA / DHA / Alpha-Tocopherol

Corn Oil

ACTIVE COMPARATOR

Two gelatine capsules twice a day, each containing 1 gram of corn oil. Alpha-Tocopherol (4 mg) was added to each capsule.

Drug: EPA / DHA / Alpha-TocopherolDrug: Corn Oil / Alpha-Tocopherol (4 mg)

Interventions

Two gelatine capsules of Omacor-R (Pronova AS, Oslo) twice a day, each containing 850-882 mg eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) as ethylesters in the average ratio of EPA to DHA of 1:2. Alpha-Tocopherol (4 mg) was added to each capsule.
