Heart failure is a condition in which the heart can't pump enough blood to meet the body's needs. In some cases, the heart can't fill with enough blood. In other cases, the heart can't pump blood to the rest of the body with enough force. Some people have both problems.
The term "heart failure" doesn't mean that your heart has stopped or is about to stop working. However, heart failure is a serious condition that requires medical care.
Heart failure develops over time as the heart's pumping action grows weaker. The condition can affect the right side of the heart only, or it can affect both sides of the heart. Most cases involve both sides of the heart.
Right-side heart failure occurs if the heart can't pump enough blood to the lungs to pick up oxygen. Left-side heart failure occurs if the heart can't pump enough oxygen-rich blood to the rest of the body.
Right-side heart failure may cause fluid to build up in the feet, ankles, legs, liver, abdomen, and the veins in the neck. Right-side and left-side heart failure also may cause shortness of breath and fatigue (tiredness).
Heart failure is a very common condition. About 5.8 million people in the United States have heart failure.
Both children and adults can have the condition, although the symptoms and treatments differ. This article focuses on heart failure in adults.
Currently, heart failure has no cure. However, treatments—such as medicines and lifestyle changes—can help people who have the condition live longer and more active lives. Researchers continue to study new ways to treat heart failure and its complications.

Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. To find clinical trials that are currently underway for Heart Failure, visit www.clinicaltrials.gov.

Risk factors identified at diagnosis help predict outcomes for children with rare heart condition
A long-term study of children with a complex heart condition called hypertrophic cardiomyopathy (HCM) found that risk factors identified at diagnosis help to predict outcomes for children with this rare condition.

New NHLBI Program Trains Scientists to Bring More Science Out of the Lab and into the Patient Care Marketplace
The NHLBI updates Health Topics articles on a biennial cycle based on a thorough review of research findings and new literature. The articles also are updated as needed if important new research is published. The date on each Health Topics article reflects when the content was originally posted or last revised.
