Contrary to previous reports, omega-3 fatty acids and vitamin D3 supplements do not prevent the development of atrial fibrillation (AFib). This emerges from new evidence presented at the American Heart Association’s 2020 Scientific Sessions.
The authors pointed to previous studies that suggested that omega-3 fatty acids in fish oils and vitamin D might limit a person’s risk of developing AFib. To investigate these results, they organized their own placebo-controlled, randomized clinical trial.
The VITAL Rhythm Trial lasted five years from 2012 to 2017 and included more than 25,000 patients aged 50 and over. All patients had no history of AFib at the time of admission. The mean age of the patients was 67 years. While some patients were given fish oil and / or vitamin D3 supplements, others were simply given a placebo.
