Fish oil and vitamin D supplements are not effective in preventing atrial fibrillation


The latest research in the 2020 American Heart Association scientific sessions revealed that taking omega-3 fatty acids and vitamin D supplements does not increase or decrease the risk of developing atrial fibrillation of the heart, and atrial fibrillation is a rapid and irregular heartbeat caused by chaotic electrical signals in the two chambers of the heart.

According to “Medical News”, atrial fibrillation is the most common heart rhythm disorder and can lead to blood clots, strokes, heart failure and other heart complications.

The risk of developing atrial fibrillation increases with age, hypertension, and heavy alcohol use and can be common in many family members.

Evidence from previous surveillance studies has been mixed, pointing to both the potential health risks and the benefits of fish oil – a source of omega-3 fatty acids – and vitamin D for atrial fibrillation.

“Once established, atrial fibrillation is difficult to treat and causes symptoms that can compromise patients’ quality of life and current treatment options have limited long-term success and significant risks,” said Christine M. Albert, president founder of the department of cardiology at the Smidt Heart Institute in Cedar Sinai, USA and lead author of the study Preventive strategies are urgently needed.

An experience VITAL rhythm It is the first randomized placebo-controlled clinical trial investigating preventative treatments for atrial fibrillation.

This study evaluated whether supplementing with vitamins D3 (2,000 IU / day) and omega-3 fatty acids (EPA: DHA With 1.2: 1 ratio; 840 mg / day) may reduce the risk of developing atrial fibrillation compared to placebo.

The five-year study, from 2012 to 2017, included 25,119 adults, aged 50 and over, with no history of atrial fibrillation.

Approximately half of the participants were female, 21% were brown, and the mean age was 67. Diagnosis of atrial fibrillation was determined by the participant’s self-assessment and application data from the Centers for Medicare and Medicaid Services.

Albert added: “These findings do not support the use of omega-3 fatty acids or vitamin D to prevent atrial fibrillation. However, the results provide confirmation that these supplements do not increase the overall risk of developing atrial fibrillation. It appears. generally be safe for patients who take them. ” Supplements for other reasons. “
