Synopsis

Rating (out of 5): 3

Fatty acids, particularly omega-3 polyunsaturated fatty acids (PUFAs) such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have been studied for their potential benefit in managing congestive heart failure (CHF). Several clinical trials and meta-analyses provide moderate scientific evidence supporting their adjunctive use in heart failure management. The GISSI-HF trial, a large randomized controlled trial, reported that supplementation with omega-3 fatty acids led to a small but statistically significant reduction in mortality and hospitalization in patients with chronic heart failure. The proposed mechanisms include anti-inflammatory effects, antiarrhythmic properties, and improvement in endothelial function, all of which may be beneficial in the context of heart failure. However, the magnitude of benefit is generally modest, and omega-3 fatty acids are viewed as an adjunct rather than a primary therapy. Guidelines from the American Heart Association and other major cardiovascular societies recognize omega-3 supplementation as a possible supportive measure for selected patients with heart failure, but do not recommend it as standard therapy for all patients. Other types of fatty acids (e.g., saturated or monounsaturated) are not specifically recommended for CHF, and some may even be detrimental. In summary, there is moderate scientific support for the use of omega-3 fatty acids in CHF, but they should be considered as part of a comprehensive management plan rather than a standalone treatment.
