Prescription medication with omega-3 fatty acids may have cardiovascular benefits, new research suggests.
Triglycerides are fats in the blood. Some are naturally produced by the liver, while others come from calories that the body doesn’t need to use immediately. The more calories a person takes in, the likelier they are to have a high triglyceride count.
Estimates suggest that around a quarter of the adult population of the United States may have triglyceride levels above 150 mg/dl.
Thankfully, there are a few ways to reduce triglyceride levels. Getting regular exercise, reducing alcohol consumption, and eliminating sugar and refined carbohydrates can help, as can other steps to maintain a healthy weight, such as swapping saturated for unsaturated fats.
Turning to medication
Sometimes, these changes are not enough to make a substantial difference. If this is the case, a doctor will rule out conditions such as type 2 diabetes and hypothyroidism before prescribing medication for high triglyceride levels.
Currently, two triglyceride-lowering prescriptions exist, and both involve omega-3 fatty acids. One contains a fatty acid called eicosapentaenoic acid (EPA). The other combines EPA with a second fatty acid: docosahexaenoic acid (DHA).
Previous research had not compared the effects of these medications. But a recent review-based advisory from the AHA, published in its journal Circulation, has concluded that both are equally effective.
The researchers based their findings on an analysis of 17 clinical trials and found that “Treatment with 4 grams daily of any of the available prescription choices is effective,” explains first study author Ann Skulas-Ray, Ph.D., from the Department of Nutritional Sciences at the University of Arizona, in Tucson.
Skulas-Ray also notes that these medications can be “used safely in conjunction with statin medicines that lower cholesterol.”
Plenty of positives
The Food and Drug Administration (FDA) have currently only approved prescription omega-3 fatty acid medication to treat triglyceride levels that are extremely high, above 500 mg/dl.
But the authors of the current advisory found that a 4-gram daily dosage could reduce triglyceride levels of 200–499 mg/dl by between 20% and 30%. This would apply to the majority of people with high triglyceride levels.
The researchers also noted that the medication that contains both EPA and DHA did not increase levels of LDL cholesterol, the “bad” type, in people with triglyceride levels below 500 mg/dl.
They also found that people with very high triglyceride levels who took EPA-only medication combined with statin therapy experienced a 25% decrease in major cardiovascular events, including stroke and heart attack.
Skulas-Ray points out that people should not try to treat high triglyceride levels at home with nonprescription omega-3 supplements. “Dietary supplements containing omega-3 fatty acids are not regulated by the FDA,” she explains.
“They should not be used in place of prescription medication for the long term management of high triglycerides.”
In 2017, the AHA released an advisory citing a lack of evidence to support the claim that fish oil supplements could prevent cardiovascular disease in the general population.
The AHA have, however, noted that people who have experienced a heart attack or heart failure may benefit from the supplements.
Congestive heart failure: What you need to know
Congestive heart failure means that the heart is unable to pump blood around the body properly. There are different types of heart failure, but they all result from conditions that weaken the heart muscles. There is no cure, but it is possible to manage the condition. We discuss causes, symptoms, and treatments here.
What to know about cardiovascular disease
Cardiovascular disease affects the heart and blood vessels. There are many types, including coronary artery disease, angina, and heart failure. Following a heart-healthy diet and regularly exercising can help prevent it, and there are many treatments available. Learn more here.
What to know about coronary heart disease
The coronary arteries supply oxygen and blood to the heart. However, when cholesterol builds up on the artery walls, they can narrow. This results in coronary heart disease, the most common type of heart disease in the United States. Here, we cover causes, symptoms, risk factors, prevention, and treatment.
