Frequently Asked Questions About Heart Failure

What Is Heart Failure?

When you have this condition your heart works less efficiently. When that happens, it can't pump enough blood that you need.

The chambers of your heart can respond by stretching to hold more blood to pump. This helps to keep the blood moving, but in time, your heart muscle walls may weaken and won't be able to pump as strongly.

Your kidneys may react to all this by causing your body to hold on to fluid and salt. The fluid may build up in your arms, legs, ankles, feet, lungs or other organs.

What Are the Symptoms?

They may be mild, moderate, or severe, and can include things like:

Congested lungs. Fluid backup in your lungs can make you short of breath when you exercise or have trouble breathing while you rest. Air is often harder to get when you're lying flat in bed. You may also wheeze or get a dry, hacking cough.

Fluid and water buildup. Less blood to your kidneys causes you to hang on to fluid. That means your ankles, legs, and belly may swell. You may hear your doctor call that swelling edema.

The extra fluid can also make you gain weight, and you may need to pee more during the night. It may also cause bloating, which can make you nauseated and less hungry.

Dizziness, fatigue, and weakness. Less blood to your major organs and muscles makes you feel tired and weak. Less blood to the brain can bring dizziness or confusion.

Rapid or irregular heartbeats. This happens because your heart beats faster to pump enough blood.

If you have heart failure, you may have one or all of these symptoms, or you may have none of them.

Your symptoms may not be related to how weak your heart is.

What's the Outlook for People With Heart Failure?

A lot depends on how well your heart is working, your symptoms, and how well you follow and respond to your treatment plan. With the right care, heart failure may not stop you from doing the things you enjoy.
