A new study released at the European Society of Cardiology Congress 2010 in Stockholm, Sweden suggests that those who have suffered at least one heart attack may not get any help from Omega-3 fatty acids to prevent them from additional cardiovascular diseases like myocardial infarction.

There is, however, a warning issued through the study that it does not seem to provide a definite conclusion that by using omega-3 fatty acids are useless in patients who have gone through myocardial infarction.

The researchers observed that a new meta-analysis of randomized controlled trials of fish oil supplements with at least one gram per day of the omega-3 fatty acids called eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) lessened the cardiac mortality in heart patients by 20 percent.

In the present study the researchers tested whether a low dose of EPA and DHA, or ALA can reduce the risk of major cardiovascular events, fatal coronary heart disease and clinical sequelae of ventricular fibrillation.

Due to these facts and their possible implications, the results of the trial may not apply to American patients.
