Institute researchers have found that taking high doses of fish oil supplements—specifically one gram or more per day—may increase the risk of developing atrial fibrillation, an abnormal heart rhythm disturbance that can lead to sudden death. The study, published in the Journal of the American College of Cardiology, was conducted by researchers at the University of California, San Francisco (UCSF) School of Medicine.
The study was funded by the National Heart, Lung, and Blood Institute (NHLBI) and the U.S. Department of Health and Human Services (HHS) National Institute of Diabetes and Digestive and Kidney Diseases, which is part of HHS. It was also supported by a grant from the NHLBI to the Heart and Stroke Foundation of America (HSFA), a non-profit organization dedicated to improving the quality of life for people living with heart disease, stroke, or other cardiovascular diseases.

Does fish oil increase heart rate?
Many different populations have been observed with and without cardiovascular disease, with and without the effect of Omega 3 fatty acids on heart rate. According to a meta-analysis of 30 randomized, double-blind, placebo-controlled trials, fish oil consumption can significantly reduce heart rate, blood pressure, and triglyceride levels in patients with chd. Trials. PubMed the effect on blood lipids of fish consumption on cardiovascular risk factors.
Can omega-3 help with heart palpitations?
According to a new study published in the Journal of the American College of Cardiology, people with higher-than-average levels of Omega 3 in their blood may be less likely to develop atrial fibrillation.
The study, conducted by researchers at the University of Texas Southwestern Medical Center in Dallas and the Texas Heart Institute in Houston, found that people who had the highest amounts of EPA, DHA and EPA plus DPA (docosahexaenoic acid), a type of polyunsaturated fatty acid found in fish oil, had a 40 percent lower risk of developing heart disease than people with lower levels.
The study was funded by the National Heart, Lung, and Blood Institute, the U.S. Department of Health and Human Services (HHS), and Texas A&M University Health Science Center at Texas Health Presbyterian Hospital.
What do cardiologists say about fish oil?
He said fish oil can no longer be considered harmless. Becker no longer recommends fish oil supplements for preventing or treating AFIB. FDA has not yet responded to a request for comment.
Who should not take fish oil?
People using blood thinners, such as warfarin, should not take fish oil or other omega 3 supplements because of the risk of heart disease, according to a new study. The study, published in the journal Circulation: Cardiovascular Quality and Outcomes, looked at data from more than 1.5 million people who were followed for an average of 10 years.
The researchers found that people with high blood pressure, high cholesterol or high triglycerides were more likely to have heart attacks and strokes than those who had lower levels of these risk factors. People who took fish-oil supplements were also at increased risk for heart attack and stroke, the study found.
Why do I keep getting heart palpitations?
Stress, exercise, medication or, rarely, a medical condition can trigger them. Heart palpitations are usually harmless, even though they can be worrisome. Occasionally, heart palpitations can be a symptom of a more serious heart condition, such as an irregular heartbeat, that requires immediate medical attention.
Do cardiologists recommend fish oil?
These results prompted the American Heart Association to recommend fish oil supplements to patients with heart disease, and many cardiologists followed suit. It wasn’t long before the benefits of fish oil were being promoted for people without a history of heart problems.
In the early 1990s, a study published in the New England Journal of Medicine found that people who took a daily supplement of omega-3 fatty acids had a lower risk of death from all causes than those who didn’t take the supplement at all.
The study, however, was based on a small number of people, so it’s hard to whether the results would hold up in a larger study.
