“Our study suggests that fish oil supplements are associated with a significantly higher risk of atrial fibrillation in patients at increased cardiovascular risk,” said Dr. Salvatore Carbone from the Department of Kinesiology and Health Sciences at the College of Humanities & Sciences, Virginia Commonwealthal University.
“Although a clinical study showed positive cardiovascular effects from supplementation, the risk of atrial fibrillation should be considered when prescribing or buying such drugs over the counter, especially in those prone to arrhythmias,” he added.
The researchers concluded that their study suggests that fish oil supplements are linked to an increased risk of atrial fibrillation in patients with elevated plasma triglycerides and an increased cardiovascular risk, and suggest that the risk of atrial fibrillation be taken into account when taking omega supplements -3 fatty acids are prescribed to this group.
