Heart failure means that your heart muscle does not pump as much blood as your body needs. Failure does not mean that your heart has stopped. It means that your heart is not pumping as well as it should.
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 include:
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 emergency care.
Your doctor may diagnose heart failure based on your symptoms and a physical examination. 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 is the best and simplest way to find out 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 getting worse. It 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.
Depending on the cause of your heart failure, you might need surgery to help your heart work better. For example:
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:
To stay as healthy as possible, work closely with your doctor. Have all your tests, and go to all your appointments. It is also important to:
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 does not get rid of them.
Heart failure can also lead to other health problems. These may include:
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.
You may want to think about planning for the future. An advance care plan lets doctors know what type of life-support measures you want if your health gets much worse. You can also choose a substitute decision-maker to make decisions in case you are not able to. It can be comforting to know that you will get the type of care you want.
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, counselling, or both may help you cope.

Many problems can cause heart failure, including damage to the heart's muscle, valves, or electrical system. These can all affect how well the heart pumps.
Certain triggers, 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 cardiogenic shock.
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 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:
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:
Sudden heart failure is an emergency. You need care right away.

Heart failure is usually caused by another health problem, often coronary artery disease or high blood pressure. So anything that increases your risk for one of those problems also increases your risk for heart failure.
The number of people who have heart failure is growing. Two of the reasons for this growth are that people in general are living longer and people who already have heart failure are also living longer. The risk of heart failure rises as a person gets older. So more and more people are expected to have heart failure as the population gets older.

Call 911 or other emergency services immediately if you have:
Call your doctor soon if you have symptoms of heart failure, which include:
Also call your doctor soon if you have been diagnosed with heart failure and your symptoms get worse. In general, it is a good idea to call your doctor anytime you have a sudden change in symptoms.
Call your doctor right away if you have a pacemaker or ICD and think you have an infection near the device. Signs of an infection include:
You can try home treatment for symptoms such as mild fluid buildup (edema) and feeling very tired. But sudden shortness of breath, even if it is mild, should always be checked by your doctor.
Your family doctor or general practitioner can check early symptoms of heart failure. You may be referred to a specialist, such as:
A cardiovascular surgeon may perform surgical repair of heart valves or a heart transplant.

Heart failure is a complex problem. So you will likely have several different tests over time. These tests can:
If you have symptoms that suggest heart failure, you may have:
An echocardiogram is the best and simplest way to diagnose heart failure. It also can help guide treatment.
Sometimes, because of a person's weight, breast size, or severe lung disease, an echocardiogram might not be accurate. If that happens, a cardiac blood pool scan may be done instead. It checks how well the left ventricle is pumping. But it's not as good at finding heart valve disease and a thick heart muscle.
Tests also may be done to find areas of the heart that are not getting enough blood. These tests include:

Your treatment for heart failure depends on:
Sometimes heart failure can be fixed if another problem can be corrected, such as by replacing a heart valve or treating hyperthyroidism.
Heart failure caused by a heart attack may be treated with coronary artery bypass surgery or angioplasty, medicine, and cardiac rehabilitation.
In the early stages of heart failure, you'll take medicines and make lifestyles changes that can improve your symptoms. Treatment also may prevent more damage to your heart.
You will have regular doctor visits to see how treatment is working and to make changes to your care as needed.
You will likely take:
You also will likely take medicines to treat the cause of your heart failure. For more information, see the Medications section.
It's very important to take your medicines exactly as your doctor prescribes.
You will need to make some changes in your daily life to treat heart failure. Your doctor may ask you to:
Making lifestyle changes can be hard. For more information, see the Living With Heart Failure section.
You will keep following your lifestyle changes, such as limiting sodium, not smoking, and being active.
Your doctor will add other medicines and other treatments as you need them. Your doctor also will try to prevent or treat problems—such as fever, arrhythmia, and anemia—that can lead to sudden heart failure.
Your treatment may include:
In some cases when standard treatment doesn't help, you may have other treatments. These include:
But these are options for only a very small number of people.
As your heart failure gets worse, you may want to think about hospice palliative care. It's a kind of care for people who have illnesses that don't go away and often get worse over time. It's different than care to cure your illness. But some people combine both types of care.
Hospice palliative care:
If you are interested in hospice palliative care, talk to your doctor. He or she may be able to manage your care or refer you to a doctor who specializes in this type of care.
For more information, see the topic Hospice Palliative Care.
Because heart failure tends to get worse over time, it's important to think about what kind of care you would like at the end of your life. It's also important that your doctor and family know what you want.
An advance care plan includes documents that tell doctors how to care for you at the end of your life. For more information, see End-of-Life Decisions.

You can feel better when you have heart failure by taking your medicines as directed, having a healthy lifestyle, and avoiding things that make heart failure worse. To find out the things you can do every day, what to watch for, and when to call a doctor, see:
Avoid triggers, such as too much salt (sodium) and certain medicines, that can cause sudden heart failure. For more information, see:
![]() One Man's Story: Pete, 70 "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. "It took a little time to get used to sleeping with a mask. But I'm sleeping much better. Now if I wake up, it's only once, and I go right back to sleep. I feel so much better during the day."—Pete This story is based on information gathered from many people living with heart failure. |
Many people with heart failure have trouble sleeping. Your doctor may be able to find out what is causing your sleep problems and help you get a good night's sleep.

Most people with heart failure can still have an active sex life. But sexual problems are common. Your interest may drop, or you may have shortness of breath or other symptoms that limit your ability to have sex. Men may have erection problems.
Talk to your doctor. You can get help for erection problems or other sexual troubles. You also can follow some tips to make sex easier on your heart. For more information, see the topics:
It can be rewarding to help a loved one with heart failure. But it's also a lot of work. And it can be hard emotionally.
If you are taking care of a loved one, make sure that you also take care of yourself. This can mean taking breaks by getting help from family or friends. You also may be able to use respite care. These services provide someone who will stay with your loved one while you get out of the house for a few hours. For more information, see:

Heart failure brings big changes to your life. You may struggle with sadness and worry. You may wonder if you'll still be able to enjoy your life. Coping with your feelings and seeking help when you need it can help you live better with heart failure.
![]() One Woman's Story: Joan, 54 "I would sit at my kitchen table and feel I was in this cloud of dread. I didn't feel like me. I felt like, 'I'm never going to be me again.'"—Joan Read about how Joan got help for depression and anxiety. |
Heart failure can be hard on your emotions. You may feel depressed that you can't do some of the things you used to do. You may worry about your future. And symptoms of heart failure, such as shortness of breath, can make this anxiety worse.
These feelings are common. Talk to your doctor if you have symptoms of depression or are worried a lot. Depression and anxiety can be treated with counselling and medicine.
You also can help yourself feel better by changing your "self-talk." Those are the things you tell yourself about how you're coping. Negative thoughts can make you feel bad. Changing the way you think can change the way you feel. To learn how to think in a positive way, see:
For more information, see the topics:
The challenges of living with heart failure can increase your stress. And stress can make living with heart failure even harder. Stress also can disturb your sleep and make depression and anxiety worse. Here are some things that can help your body, mind, and spirit:
Emotional support from friends and family can help you cope with the struggles of heart failure. You might want to think about joining a heart failure support group. Ask your doctor about the types of support that are available where you live.
Meeting other people with the same problems can help you know you're not alone. If you're shy or aren't a joiner, you can look at an online support group. Even though people online aren't talking face-to-face, they're sharing their feelings and creating a community.
You probably will need to take several medicines to treat heart failure, even if you don't have symptoms yet. Medicines don't cure heart failure. But they can help your heart work better and improve any symptoms that you do have.
Medicines can:
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. For more information, see:
The medicines you take will depend on the type of heart failure you have. Some of the medicines treat the heart's pumping problems (systolic heart failure), while others treat problems with filling (diastolic heart failure). The most commonly used medicines are listed below.
These include:
Medicines that might be used include:
You also may take other medicines for health problems that can cause heart failure or for problems caused by heart failure. These problems include irregular heart rhythms, blood clots, and high blood pressure.
The medicines include:
Talk to your doctor before you take any over-the-counter medicines. Some of them might make your symptoms worse. For more information, see:

People who have heart failure may have surgery to:
For more information on bypass surgery and angioplasty, see the topic Coronary Artery Disease.
If you have heart failure, you may get a device to fix a deadly heart rhythm or to help your heart pump better.
![]() One Woman's Story: Joyce, 83 Getting a pacemaker has "made all the difference in the world. I could work in my yard, and walk my dog."—Joyce Read about how a pacemaker helped Joyce be more active. |
Cardiac resynchronization therapy (CRT) uses a biventricular pacemaker which makes the heart’s lower chambers (ventricles) pump in the right order. 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. For more information on pacemakers, see:
If you get a pacemaker, you have to be careful not to get too close to some devices with strong magnetic or electrical fields. These include MRI machines, battery-powered cordless power tools, and CB or ham radios. But most everyday appliances are safe. For more information, see:
A pacemaker may be used alone or along with an implantable cardioverter-defibrillator (ICD) for heart failure.
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. For more information, see:
If you get an ICD, you have to be careful not to get too close to some devices with strong magnetic or electrical fields. These include MRI machines, battery-powered cordless power tools, and CB or ham radios. But most everyday appliances are safe. For more information, see:
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 more blood. 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.
In some cases you might have:
Talk to your doctor before you take any over-the-counter medicine or supplement. There's no strong evidence that vitamins or other supplements can help treat heart failure. They are used along with medical heart failure treatments, not instead of treatment.
But you may still hear about supplements that might improve heart failure symptoms. But no supplement has been shown definitely to relieve heart failure or help you live longer.
Examples include coenzyme Q10, fish oil, and hawthorn.
Heart failure tends to get worse over time. So you need to decide what kind of care you want at the end of your life.
It can be hard to have talks with your doctor and family about the end of your life. But making these decisions now may bring you and your family peace of mind. Your family won't have to wonder what you want. And you can spend your time focusing on your relationships.
You will need to decide if you want life-support measures if your health gets very bad. An advance care plan includes a document that tells doctors how to care for you at the end of your life. This care includes electronic devices that are used for heart failure, such as pacemakers. You also can say where you want to have care. And you can name someone who can make sure your wishes are followed.
