What foods can fight heart failure?

　　Researchers in Italy and the United States also found that cholesterol-lowering drugs have little effect on heart failure patients, while fish oil can help the condition and reduce mortality to a certain extent.
　　
　　Researchers studied more than 7,000 heart failure patients through a double-blind comparative experiment and found that unless high cholesterol is also present, heart failure itself does not require the use of cholesterol-lowering drugs, and its benefits to patients are not as obvious as fish oil.
