Radionuclide ventriculography is a test that uses very low doses of a radioactive substance that is injected into your blood. It travels to the heart and produces pictures that show your doctor how well your heart is pumping. The radioactive substance is safe and leaves your body completely. Much can be done to improve the heart's pumping and to treat the symptoms, but heart failure can't be completely cured.

Other changes in diet may be advised, depending on other health problems you may have. It sometimes helps to talk with other people who have similar problems. Many different medicines are used to treat heart failure. You may need one or more medicines, depending on your symptoms. Your doctor will talk about these medicines with you.
