The term "heart failure" makes it sound like the heart is no longer working at all and there’s nothing that can be done. Actually, heart failure means that the heart isn’t pumping as well as it should be.

Your body depends on the heart’s pumping action to deliver oxygen- and nutrient-rich blood to the body’s cells. When the cells are nourished properly, the body can function normally.

With heart failure, the weakened heart can’t supply the cells with enough blood. This results in fatigue and shortness of breath. Everyday activities such as walking, climbing stairs or carrying groceries can become very difficult.

Heart failure is a serious condition, and usually there’s no cure. But many people with heart failure lead a full, enjoyable life when the condition is managed with medications and healthy lifestyle changes. It’s also helpful to have the support of family and friends who understand your condition.
