Taking fish oil supplements can help improve cardiac function in patients of cardiac insufficiency, suggests a new study.
Fish oil is rich in omega-3 fatty acids. According to the American Heart (AHA), Omega-3 is a "good" fat that has been linked to the reduction of the risk of cardiovascular disease, hypertension, arrhythmia and atherosclerosis (clogged arteries).
Current research has found giving patients with heart failure fish oil have increased their cardiac function by more than 10%.
The study, published in the journal of the American College of Cardiology, scientists give randomly 133 patients heart failure with minimal symptoms and already on the standard treatment, high-dose Omega-3 fatty acid supplements or placebo. "Standard therapy" referred patients receiving medications such as beta-blockers.
And after a year, participants in the study for the Omega-3 supplement had a 10.4% increase in cardiac function. Conversely, persons given placebo had a decrease of 5% of cardiac function. In addition, persons who take fish oil had improved exercise capacity. For fish oil group, exercise time rose by 7.5%, but the placebo group lost time exercise 4.8%.
Oxygen also improved in study participants taking blood oil fish. Fish oil has stimulated the blood oxygen 6.2%. Placebo resulted in a decrease of 4.5%.
Although scientists urge more research needs on the benefits of fish oil, they say that Omega-3 fatty acids are promising to improve the quality of life of patients with congestive heart failure.
Fish oil-derived supplements are not the only source of Omega-3 fatty acids. Plant foods like walnuts and algae are rich in omega-3. Some algae are often used to make vegan alternative to fish oil supplements.
Simply consume fish is another option. Fatty fish such as salmon, the swordfish and sardines, are rich in omega-3. The AHA recommends eating fatty fish like these at least twice per week.
