[Omega-3 fatty acids and cardiovascular diseases].

Most--but not all--epidemiological studies have demonstrated that omega-3 intake, either from nutrition or supplementation, reduces cardiovascular risk. A few intervention studies have shown a reduction of studden death in patients followed after a myocardial infarction. However EBM studies from the Cochrane Library do not confirm the real advantage of omega-3 in any group of subjects. Probably, the most interesting prescription of omega-3 supplementations would benefit to the patients after myocardial infarction, in addition to drugs that have proved their efficacy (aspirine, beta-blocker statin and ACE inhibitor).
