Heart failure means that your heart muscle doesn't
pump as much blood as your body needs. Failure doesn't mean that your heart
has stopped. It means that your heart is not pumping as well as it
Because your heart cannot pump well, your body tries to
make up for it. To do this:
Your body has an amazing ability to make up for heart
failure. It may do such a good job that you don't know you have a disease. But
at some point, your heart and body will no longer be able
to keep up. Then fluid starts to build up in your body, and you have symptoms
like feeling weak and out of breath.
This fluid buildup is called
congestion. It's why some doctors call the disease congestive heart failure.
Heart failure usually gets worse over time. But treatment can
slow the disease and help you feel better and live longer.
Anything that damages
your heart or affects how well it pumps can lead to heart failure. Common causes of heart failure are:
Other conditions that can lead to heart failure
Symptoms of heart failure
start to happen when your heart cannot pump enough blood to the rest of your
body. In the early stages, you may:
As heart failure gets worse, fluid starts to build up in
your lungs and other parts of your body. This may cause you to:
If your symptoms suddenly get worse, you will need
Your doctor may
diagnose heart failure based on your symptoms and a physical exam. But you will
need tests to find the cause and type of heart failure so that you can get the
right treatment. These tests may include:
An echocardiogram can help show if you have heart failure, what type it is, and what
is causing it. Your doctor can also use it to see if your heart failure is
This test can measure how much blood your heart pumps to your body.
This measurement is called the
ejection fraction. If your ejection fraction gets
lower and you are having more symptoms, it means that your
heart failure is getting worse.
Most people with heart failure need to take several
medicines. Your doctor may prescribe medicines to:
It is very important to take your medicines exactly as
your doctor tells you to. If you don't, your heart failure could get worse.
You might need to have a pacemaker or a defibrillator (ICD) if you have a
problem with your heart rhythm. A pacemaker can help your heart pump blood better. An ICD can prevent a dangerous heart-rhythm problem.
Lifestyle changes are an important part of treatment.
They can help slow down heart failure. They may also help control other
diseases that make heart failure worse, such as high blood pressure, diabetes,
and coronary artery disease.
The best steps you can take are to:
Ask your doctor if cardiac rehab is right for you. Rehab can give you education and support that help you learn self-care and build new healthy habits, such as exercise and healthy eating.
To stay as healthy as possible, work closely with your
doctor. Have all your tests, and go to all your appointments. It is also
Medicines and lifestyle changes can slow or even reverse heart failure
for some people. But heart failure often gets worse over time.
Early on, your symptoms may not be too bad. As heart failure
gets worse, you may need to limit your activities.
Treatment can often help reduce symptoms, but it usually doesn't get rid of
Heart failure can also lead to other health problems. These
Your doctor may be able to give you medicine or other
treatment to prevent or treat these problems.
Heart failure can
get worse suddenly. If this happens, you will need emergency care. To prevent
sudden heart failure, you need to avoid things that
can trigger it. These include eating too much salt, missing a dose of your
medicine, and exercising too hard.
Knowing that your health may get worse can be hard. It
is normal to sometimes feel sad or hopeless. But if these feelings last, talk
to your doctor. Antidepressant medicines, counseling, or
both may help you cope.
Health Tools help you make wise health decisions or take action to improve your health.

such as too much sodium or not taking medicines the right way, may
suddenly make heart failure worse. This can sometimes cause deadly
problems such as
pulmonary edema or
At first you may not have any
symptoms from heart failure. For a while, your heart and body can make up for heart failure. For example, your heart can pump faster and pump more blood with each beat. This is called compensation.
But as your heart has more
trouble pumping enough blood to your body, you will likely have symptoms. These symptoms may get worse or change if your heart failure gets worse.
Symptoms of heart failure
start to happen when your heart can't pump enough blood to the rest of your
body. In the early stages, you may:
There is more than one type of heart failure. Each type is based on what problem in the heart is causing it to not pump as much blood as normal.
Heart failure is grouped-or
classified-according to symptoms.
Your treatment is based partly on what class of symptoms you
There's also another way to define heart failure.
It's based on the
stages you might go through as your heart failure gets
worse. Your doctor also may make treatment choices based on your stage of heart
Sometimes your symptoms may get worse very quickly. This is
called sudden heart failure. It causes fluid to build up in your lungs, causing
congestion. (This is why the problem is often called congestive heart
failure.) Symptoms may include:

You need care right away.
Your risk for having heart failure is higher if you have certain risk factors. A risk factor is anything that increases your chance of having a particular problem.

Many different types of doctors and nurses can treat you for heart failure, including your family doctor.
Heart failure is a complex
problem. So you will likely have
several different tests over time. These tests can:

you may have:
echocardiogram may be used to
diagnose heart failure. It also can help guide
Tests also may be done to find areas of the heart that are not getting enough blood. These tests include:
When you're taking medicine for heart failure, you may have regular blood tests to check how the medicine is working. Or you may have a blood test to check the level of medicine in your body.
Your treatment for
heart failure depends on:
In the early stages of
heart failure, treatment can help your symptoms. It may also prevent
more damage to your heart. Treatment may include:
As part of your ongoing treatment, your doctor will also try to
prevent or treat problems-such as fever,
anemia-that can lead to
sudden heart failure. Treatment may include:
You might take part in a disease management program. These programs include a broad range of services, such as education, home health care, visiting nurses, and rehabilitation.
A very small number of people may have other treatments, including:
If you have other heart problems that may have led to heart failure, you might have treatment for those problems:
heart failure can be fixed if another problem can be corrected, such as
by treating hyperthyroidism.
Palliative care is a kind of care for people who have a serious illness. It's different from care to cure your illness. Its goal is to improve your quality of life-not just in your body but also in your mind and spirit.
You can have this care along with treatment to cure your illness. You can also have it if treatment to cure your illness no longer seems like a good choice.
Palliative care providers will work to help control pain or side effects. They may help you decide what treatment you want or don't want. And they can help your loved ones understand how to support you.
If you're interested in palliative care, talk to your doctor.

"I was having a lot of trouble getting enough sleep. I
was snoring so bad that my wife was sleeping in another room. I'd wake up 7
times a night. Sometimes I'd wake up gasping for breath. The next day I'd be so
tired that I'd fall asleep while doing my woodworking in the garage. And I was
really fuzzy-headed. I couldn't remember anything.
"I thought it
might be my heart failure. So I decided to talk to my doctor about it, and he
suggested a sleep study. I found out that I have sleep apnea. I haven't been
getting enough oxygen because of it. He put me on a CPAP machine at night. I've
used it for the past 4 months.

to sleeping with a mask. But I'm sleeping much better. Now if I wake up, it's

Medicines don't cure heart failure. But
they can help your heart work better and improve symptoms.
It's very important to take your medicines
exactly as your doctor says. If you don't, your heart
failure may get worse or you may get sudden heart failure.
The medicines you take
will depend on the type of heart failure you have. The most commonly used
medicines are listed below.
You also may take other medicines for health problems that can
cause heart failure or for problems caused by heart failure.
Talk to your doctor
before you take any
over-the-counter medicines. Some of them might make
your symptoms worse.
Surgeries for heart failure include:
Cardiac resynchronization therapy (CRT) uses a biventricular pacemaker, which makes the
heart's lower chambers (ventricles) pump together. This can help your heart pump blood better.
This type of pacemaker
can help you feel better so you can be more active. It also can help keep you
out of the hospital and help you live longer.
If you get a pacemaker, you have to be careful
not to get too close to some devices with strong magnetic or electrical fields.
MRI machines (unless your pacemaker is safe for an MRI), battery-powered cordless power tools,
and CB or ham radios. But most everyday appliances are safe.
A pacemaker may be used alone or along
with an implantable cardioverter-defibrillator (ICD) for heart
Implantable cardioverter-defibrillators (ICDs) can
prevent sudden death from an abnormal heart rhythm and may help you live
longer. An ICD checks the heart for very fast
and deadly heart rhythms. If the heart goes into one of these
rhythms, the ICD shocks it to stop the deadly rhythm and
returns the heart to a normal rhythm.
If you get an ICD, you have to be careful not
to get too close to some devices with strong magnetic or electrical fields.
MRI machines (unless your ICD is safe for an MRI), battery-powered cordless power tools,
and CB or ham radios. But most everyday appliances are safe.
An ICD may be used alone or along
with a pacemaker for heart failure.
Ventricular assist devices (VADs), also known as heart
pumps, may be placed into the chest to help the heart pump
VADs can keep people alive until
a donor heart is available for transplant. In some cases, VADs may also be used
as an alternative to heart transplant for long-term treatment. VADs are used in people who have severe heart failure.

to your doctor before you take any over-the-counter medicine or
supplement. They are used along with medical treatments for heart failure, not instead of treatment.
You may hear
about supplements, vitamins, or hormones that might improve heart failure
Fish oil (omega-3 fatty acid) supplements have been shown to help some heart failure patients. In some studies, fish oil supplements, taken along with other heart failure medicines, helped people stay out of the hospital and live longer.footnote 2
No other supplement, vitamin, or hormone has been shown definitely to relieve heart
failure or help you live longer.
