Omega-3s May Help Relieve Depression Symptoms in People with Chronic Heart Failure

Many people with chronic heart failure suffer from depression. A recent study suggests that a higher Omega-3 Index may decrease symptoms of depression in people with chronic heart failure.


Participants in the study included 108 people with chronic heart failure who were diagnosed with depression based on their scores on the Hamilton Depression Scale. Over the course of 12 weeks, one third of the participants took a supplement of 2 grams of 400/200 EPA:DHA omega-3s, one third took a supplement that was 2 grams of pure EPA, and one third took a corn oil placebo.


Following supplementation, the EPA/DHA group had an average Omega-3 Index of 6.79%; the EPA-only group had an average index of 6.32%; and the placebo’s average index was 4.61%. For the 80 participants who took at least 70% of their supplements, the numbers were 7.32%, 7.11%, and 4.42%, respectively.


The researchers found that the social functioning measurement of the 36-item Short Form Health Survey improved notably in the EPA/DHA group and the EPA-only group, when compared with the placebo.


Researchers from Duke University Medical Center conducted the story. It was published on August 7, 2018, in the Journal of the American College of Cardiology.


Because omega-3 fatty-acids are not found naturally in the human body, it is especially important to make sure that they are a part of your daily diet. Oily, dark fish such as tuna and salmon are high in omega-3s. For people who don’t like fish, consider taking a daily high-quality non-fish supplement that has been tested for purity and potency.
