Despite its many benefits, vitamin D does not prevent atrial fibrillation



BASICALLY

  • Voting for its multiple health benefits, vitamin D has no effect on atrial fibrillation, a new study says.

Naturally produced by our bodies when our skin is exposed to the sun, vitamin D is essential for our good health. Also present in fatty fish meat and fish liver oils, its benefits have been proven by numerous scientific studies. Protecting our bones, cells, muscles, cardiovascular system or immune system, vitamin D on the other hand will not have a beneficial effect on the development of atrial fibrillation.

This is the conclusion reached by researchers from the Cedars-Sinai Smidt Heart Institute in a study presented at scientific sessions of the American Heart Association. “Our test results do not support taking fish oil or vitamin D supplements to prevent atrial fibrillation.”, explains Christine M. Albert, lead author of the work. However, she specified that the vitamin D supplement did not “It also did not increase the risk of atrial fibrillation, which is good news for people who are being replaced by other health problems.”.

There is no significant effect of vitamin D.

Atrial fibrillation is a heart rhythm disorder that causes the heart to beat irregularly. It can cause blood clots to form in the atria of the heart, which can then travel from the heart to the brain and cause a stroke. Atrial fibrillation can also lead to weakening of the lower chamber of the heart, leading to fluid retention or heart failure.

To date, various wake-up studies conducted on the effects of vitamin D on atrial fibrillation have led to conflicting conclusions, leaving clinicians and patients unsure of current recommendations. “This is the first major trial that has not led to a definitive outcome., says Dr. Albert.

His randomized clinical trial followed 25,000 women and men living in the United States with no history of atrial fibrillation for more than five years. At the end of the five-year follow-up, 900 participants, or 3.6%, were diagnosed with atrial fibrillation.

The results of the study show that there are no statistically significant differences between participants who were given vitamin D supplements or fish oil and those who were given a placebo.

According to researchers, it is now necessary to better inform patients about the risk of atrial fibrillation, to establish effective preventive measures, but also to continue research into this heart disorder that can have serious consequences. .

“Although these two supplements do not prevent atrial fibrillation, recent studies suggest that lifestyle changes, such as maintaining a healthy weight, controlling blood pressure and moderate alcohol consumption, may reduce the risk of atrial fibrillation.” “We must continue to educate the public about ways to reduce their risk and look for new ways to prevent this disease.”, concludes Dr. Albert.
