Vitamin D, Omega-3 don't lower atrial fibrillation risk: Study

There were no statistically significant differences between the participants who were assigned to take vitamin D or fish oil supplements and the participants who were assigned to take a placebo.

Atrial fibrillation, or AF, is the most common type of abnormal heart rhythm, causing the heart to contract irregularly and, sometimes, too quickly. It is estimated to affect 33 million people worldwide.

The condition can lead to clotting inside the atrium chamber of the heart and clots can then travel from the heart to the brain, causing a stroke. Atrial fibrillation can also lead to weakening of the bottom chamber of the heart, resulting in fluid buildup or heart failure. Importantly, it often results in significant symptoms that can adversely affect one's quality of life.

While this research is important in educating patients about effective preventive measures, Albert emphasizes the need for more research directed at avoiding the condition.

"Although these two supplements do not prevent atrial fibrillation, recent studies have suggested that lifestyle modifications such as maintaining a healthy weight, controlling blood pressure, and moderating alcohol intake may lower risk of atrial fibrillation," said Albert. "We need to continue to educate the public on ways to lower their risk as well as search for new ways to prevent this condition."
