Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Unsaturated fatty acids, particularly omega-3 polyunsaturated fatty acids (PUFAs) found in fish oil, have been studied for their potential role in the prevention and management of cardiac arrhythmias such as atrial fibrillation (AF) and palpitations. Several observational studies and some randomized controlled trials have suggested that higher intake of omega-3 PUFAs may be associated with a reduced risk of certain types of arrhythmias, including sudden cardiac death. Mechanistic studies indicate that omega-3 fatty acids can influence cardiac electrophysiology by stabilizing cell membranes, reducing inflammation, and modulating ion channels, which may help in reducing arrhythmic events. However, large-scale clinical trials have yielded mixed results. For example, some studies have not found significant benefits of omega-3 supplementation in preventing recurrent atrial fibrillation or other arrhythmias in populations with existing heart conditions. Meta-analyses generally conclude that while omega-3 fatty acids are safe and may have modest antiarrhythmic effects, the evidence is not strong or consistent enough to recommend their use as a primary treatment for heart fibrillation or palpitations. Current guidelines do not universally endorse unsaturated fatty acids for arrhythmia management, but acknowledge their potential cardiovascular benefits overall.
