Munich: Fish oil supplements may work slightly better than a popular cholesterol-reducing drug to help patients with heart failure, according to new research.
The condition, known as chronic heart failure, occurs when the organ becomes enlarged and cannot pump blood efficiently around the body.
"This reinforces the idea that treating patients with heart failure takes more than just drugs," said Dr Jose Gonzalez Juanatey, a spokesman for the European Society of Cardiology, who was not connected to the research.
The study findings were published online in the medical journal The Lancet yesterday. They were simultaneously announced at a meeting of the European Society of Cardiology in Munich.
With few effective options for heart failure patients, Juanatey said that the finding was significant because it might give patients a potential new treatment, and could change dietary recommendations for heart patients.
"With a lot of these patients, you have no other choice," said Dr Helmut Gohlke, a cardiologist at the Heart Centre in Bad Krozingen, Germany. "They've tried other treatments and are at the end of the road."
Italian researchers gave nearly 3,500 patients a daily omega-3 pill, derived from fish oils. Roughly the same number of patients were given placebo pills. Patients were followed for an average of four years.
In the group of patients taking the fish oil pills, 1,981 died of heart failure or were admitted to the hospital with the problem. In the patients on placebo pills, 2,053 died or were admitted to the hospital for heart failure.
In a parallel study, the same team of Italian doctors gave 2,285 patients the drug rosuvastatin, also known as Crestor, and gave placebo pills to 2,289 people. Patients were then tracked for about four years. The doctors found little difference in heart failure rates between the two groups.
Both studies were paid for by an Italian group of pharmaceuticals including Pfizer Inc, Sigma Tau SpA and AstraZeneca PLC.
Protection: Hale and hearty
- Omega-3 fatty acids from fish such as salmon and tuna have long been proven to offer health benefits like protecting the heart and brain, though scientists aren't exactly sure how.
- Cell membranes are made of fatty acids and fish oils may help to replace and strengthen those membranes with omega-3.
