Omega-3 Fatty Acid

Therapeutic Role of Omega-3 Fatty Acid in Congestive Heart Failure

Landmark Studies

The GISSI-HF Trial (Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto Miocardico)

• A double blind, placebo controlled trial by GISSI-HF investigator randomly assigned 6975 patients with chronic heart failure of New York Heart Association (NYHA) class II-IV to n-3 PUFA 1 g daily(n=3494) or placebo(n=3481) and were followed up for a median of 3.9 years. The study showed reduced death from any cause in n-3 PUFA group (27%) as compared to placebo group (29%). Also, the end points of deaths and admission to hospitals for cardiovascular reasons is lower in n-3 PUFA group (57%) in comparison to placebo group (59%).
• A substudy of GISSI-HF trial done in 608 chronic heart failure patients indicates a small but statistically significant advantage in n-3 PUFA group in terms of LV function in symptomatic heart failure patients of any cause.

Preventive Role of Omega-3 Fatty Acid in Congestive Heart Failure

Limited studies has shown the preventive role of n-3 PUFA in heart failure.

Landmark Studies

• A prospective cohort study in 4738 adults of >65 years without heart failure at baseline have shown that consumption of tuna and other broiled or baked fish is associated with lower incidence of heart failure, no such association is found in individuals consuming fried fish.
• Another prospective cohort study in 2735 US adults without prevalent heart disease have shown that plasma phospholipid eicosapentanoic acid (EPA) concentration is inversely related with incident CHF. This result also supports that participants with higher levels of omega-3 fatty acid are less likely to develop congestive heart failure in follow up.
