Heart failure and heart attack are two different things.
A heart attack occurs suddenly and unexpectedly when the arteries supplying blood to the heart are blocked and typically results in the death of part of a heart muscle.
Heart failure is a chronic (long-term) condition in which the heart can't pump enough blood to meet the body's needs.
However, heart failure can be caused by a heart attack. Other causes include high blood pressure and lifestyle factors.
Although heart failure is much more common for older people, young and middle-aged people can develop heart failure too. Around 4% (1 in 25) of people with heart failure are under 55.8
If you have heart failure, it does not mean your heart is about to stop working. It means your heart needs some support to do its job and there are many treatments and also lifestyle changes that can help do this.
While it does depend on the severity of the disease, generally people with heart failure should be encouraged to stay active just like everyone else. After all, the heart is a muscle and like all muscles, it will benefit from exercise.
However, many people with heart failure say they feel they have limited amounts of energy, like a battery. It is important to allocate this energy to activities throughout the day and conserve it when necessary.
Heart failure is generally a progressive condition. However, the progress of heart failure is unpredictable and different for each person.
With careful management of the disease, the severity can be reduced for some people, with symptoms easing and prognosis improving. In many cases, the symptoms remain at a stable level for quite some time.9
