Heart failure - discharge
Congestive heart failure - discharge; CHF - discharge; HF - discharge
Heart failure is a condition in which the heart is no longer able to pump oxygen-rich blood to the rest of the body efficiently. When symptoms become severe, a hospital stay may be necessary. This article discusses what you need to do to take care of yourself when you leave the hospital.
When you Were in the Hospital
You were in the hospital to have your heart failure treated. Heart failure occurs when the muscles of your heart are weak or have trouble relaxing, or both.
Your heart is a pump that moves fluids through your body. As with any pump, if the flow out of the pump is not enough, fluids do not move well and they get stuck in places they should not be. In your body, this means that fluid collects in your lungs, abdomen, and legs.
While you were in the hospital:
- Your health care team closely adjusted the fluids you drank or received through an intravenous (IV) line. They also watched and measured how much urine you produced.
- You may have received medicines to help your body get rid of extra fluids.
- You may have had tests to check how well your heart was working.
If you cough a lot, often feel weak, have lost your appetite, and need to urinate a lot at night, you might have symptoms of heart failure. Heart failure is a long-term condition that usually comes on slowly. However, it can develop suddenly, for instance, after a heart attack. You have heart failure when your heart does not pump blood out of your heart very well, or when your heart muscles are stiff and do not easily fill up with blood. When you have heart failure, your heart cannot pump enough oxygen-rich blood to the rest of your body, especially when you exercise or move around a lot. As the heart loses the ability to pump blood, blood backs up in other parts of your body, including your lungs, liver, gastrointestinal tract, and your arms and legs. The most common cause of heart failure is coronary artery disease, the narrowing of the blood vessels that supply blood and oxygen to your heart. So, how do you know if you have heart failure? Get to your doctor. You may have trouble breathing, an irregular heartbeat, swollen legs, neck veins that stick out, and sounds from fluid built up in your lungs. Your doctor will check for these and other signs of heart failure. A test called an echocardiogram is often the best test to diagnose your heart failure. Your doctor can also use this test to find out why you have heart failure, and then monitor your condition going forward every three to six months. Your doctor will talk to you about knowing your body and symptoms that mean your heart failure is getting worse. You will need to learn to watch for changes in your heart rate, pulse, blood pressure, and weight. You will also need to limit salt in your diet, stop drinking alcohol, quit smoking if you need to, exercise, lose weight if you need to, and get enough rest. Your doctor will probably ask you to take medicines to treat your heart failure. These medicines can treat your symptoms, prevent your heart failure from getting worse, and help you live longer. If you have heart failure, taking your medicines, changing your lifestyle, and treating the condition that caused heart failure can go a long way toward improving your health. But heart failure is a chronic, or long-term, illness, which means it may get worse over time. Make sure you call your doctor if you start coughing more, have sudden weight gain or swelling, or feel week. Have someone take you to the emergency room right away if you have trouble with fainting, a fast and irregular heartbeat, or feel severe crushing chest pain.
What to Expect at Home
Your energy will slowly return. You may need help taking care of yourself when you first get home. You may feel sad or depressed. All of these things are normal.
Checking Yourself at Home
Weigh yourself every morning on the same scale when you get up -- before you eat but after you use the bathroom. Make sure you are wearing similar clothing each time you weigh yourself. Write down your weight every day on a chart so that you can keep track of it.
Throughout the day, ask yourself:
- Is my energy level normal?
- Do I get more short of breath when I am doing my everyday activities?
- Are my clothes or shoes feeling tight?
- Are my ankles or legs swelling?
- Am I coughing more often? Does my cough sound wet?
- Do I get short of breath at night or when I lie down?
If you are having new (or different) symptoms, ask yourself:
- Did I eat something different than usual or try a new food?
- Did I take all of my medicines the right way at the right times?
Diet and Fluids
Your health care provider may ask you to limit how much you drink.
- When your heart failure is not very severe, you may not have to limit your fluids too much.
- As your heart failure gets worse, you may be asked to limit fluids to 6 to 9 cups (1.5 to 2 liters) a day.
You will need to eat less salt. Salt can make you thirsty, and being thirsty can cause you to drink too much fluid. Extra salt also makes fluid stay in your body. Lots of foods that do not taste salty, or that you do not add salt to, still contain a lot of salt.
You may need to take a diuretic, or water pill.
Do not drink alcohol. Alcohol makes it harder for your heart muscles to work. Ask your provider what to do on special occasions where alcohol and foods you are trying to avoid will be served.
If you smoke, stop. Ask for help quitting if you need it. Do not let anybody smoke in your home.

- Avoid fatty foods.
- Stay away from fast-food restaurants.
- Avoid some prepared and frozen foods.
- Learn fast food tips.
Try to stay away from things that are stressful for you. If you feel stressed all the time, or if you are very sad, talk with your provider who can refer you to a counselor.
Taking Your Heart Drugs
Have your entire medicine prescriptions filled before you go home. It is very important that you take your medicines the way your provider told you to. Do not take any other medicines or herbs without asking your provider about them first.
Take your medicines with water. Do not take them with grapefruit juice, since it may change how your body absorbs certain medicines. Ask your provider or pharmacist if this will be a problem for you.
The medicines below are given to many people who have heart failure. Sometimes there is a reason they may not be safe to take, though. These medicines may help protect your heart. Talk with your provider if you are not already on any of these medicines:
- Antiplatelet medicines (blood thinners) such as aspirin, clopidogrel (Plavix), or warfarin (Coumadin) to help keep your blood from clotting
- Beta blocker and ACE inhibitor medicines as well as other medicines to lower your blood pressure and treat the heart muscle
- Statins or other medicines to lower your cholesterol
Talk to your provider before changing the way you take your medicines. Never just stop taking these medicines for your heart, or any medicines you may be taking for diabetes, high blood pressure, or other medical conditions you have.
If you are taking a blood thinner, such as warfarin (Coumadin), you will need to have extra blood tests to make sure your dose is correct.
Your provider may refer you to cardiac rehabilitation program. There, you will learn how to slowly increase your exercise and how to take care of your heart disease. Make sure you avoid heavy lifting.
Make sure you know the warning signs of heart failure and of a heart attack. Know what to do when you have chest pain, or angina.
Always ask your provider before starting sexual activity again. Do not take sildenafil (Viagra), or vardenafil (Levitra), tadalafil (Cialis), or any herbal remedy for erection problems without checking first.
Make sure your home is set up to be safe and easy for you for you to move around in and avoid falls.
If you are unable to walk around very much, ask your provider for exercises you can do while you are sitting.
Make sure you get a flu shot every year. You may also need a pneumococcal vaccine (pneumonia shot). Ask your provider about this.
Your provider may call you to see how you are doing and to make sure you are checking your weight and taking your medicines.
You will need follow-up appointments at your provider's office.
You will likely need to have certain lab tests to check your sodium and potassium levels and monitor how your kidneys are working.
