What is heart failure?
Despite the way it sounds, the term "heart failure" simply means that your heart isn't pumping blood as well as it should. Heart failure does not mean your heart has stopped working or that you are having a heart attack (but, people who have heart failure often have had a heart attack in the past). Heart failure is also called congestive heart failure (CHF). "Congestive" means fluid is building up in the body because the heart isn't pumping properly.
What causes heart failure?
Heart failure has many different causes. Sometimes the exact cause cannot be found. The most common causes of heart failure are listed below:
What are the symptoms of heart failure?
Some people who have heart failure have few problems or symptoms. The following is a list of symptoms people who have heart failure might experience:
Call your doctor if you have any of these symptoms, especially if you've had heart problems before.
How will my doctor know if I have heart failure?
Your doctor will ask you about your medical history and symptoms. He or she will give you a physical exam and may order some the following tests:
An electrocardiogram records the electrical activity of your heart. It can help diagnose heart rhythm problems or damage to the heart. An echocardiogram is a test that sends out sound waves that allow your doctor to get pictures of your heart. The pictures show your doctor how well your heart is pumping.
Radionuclide ventriculography involves injecting a very small amount of a radioactive substance into your blood. This substance travels to your heart. A special camera or scanner uses the radioactive substance to produce pictures that show your doctor how well your heart is pumping. The radioactive substance is safe and leaves your body completely after the test is finished.
What treatment will I need?
Much can be done to improve how well the heart pumps and to treat the symptoms, but heart failure cannot be completely cured. An important part of treatment is taking care of any underlying problems, such as lowering high blood pressure or fixing a heart valve. Treatment also includes lifestyle changes and medicine. Here are some important things you should talk about with your doctor:
What medicines will I need to take?
Many different medicines are used to treat heart failure. You may need one or more medicines, depending on your symptoms. Your doctor will talk about these medicines with you. It may take some time to find the best type of medicine and the best dosage of medicine for you.
Several kinds of medicines are commonly used to treat heart failure:
You might need to take other medicines if you have other problems or if you experience side effects with any of these medicines.
When you're taking medicine for heart failure, you'll need to have blood tests to check your potassium level and kidney function. How often you need blood tests depends on the type and strength of medicine you are taking. Many patients take these medicines without any problems. However, if you have concerns about the medicine or think you may be having side effects, you should talk to your doctor. It's very important that you take your medicine exactly as your doctor prescribes.
How often will I need to see my doctor?
At first, you may need to be seen as often as every week to check how you're reacting to the medicine. After your doctor has adjusted your medicine and you're feeling better, you may need to be seen less often.
When should I call my doctor?
See your doctor if you have any of the signs or symptoms of heart failure listed above. Other serious problems with your heart or lungs can cause symptoms that are similar to heart failure.
I have congestive heart failure. What does it mean?
Heart failure, also called congestive heart failure (CHF) means that your heart has lost some ability to pump blood. This can cause shortness of breath, tiredness, weakness, and fluid buildup that results in swelling of the legs, ankles and feet. Congestive heart failure is serious, but many treatments can help you feel better. You will probably need to take several prescription medicines each day for your condition. Your doctor will want to know which parts of your heart are affected so that you can take the right medicine.
What causes CHF?
The most common causes of CHF are:
What can I do to help treat my CHF?
Avoid eating too much salt and salty foods (like canned vegetables or soups, chips and pizza). Salty and high-sodium foods can cause your body to retain water. Talk to your doctor before using salt substitutes because they often contain potassium and may not be good for your health either. This will depend on your kidney function and what medicines you are taking. Some people need extra potassium but other people don’t.
Although drinking a small amount of alcohol (one drink a day) seems to be helpful in some people with heart disease, drinking too much may cause heart failure and interfere with medicines. Ask your doctor if any amount of alcohol is safe for you.
Keep your blood pressure well controlled. High blood pressure strains your heart and further weakens it.
You’ll be healthier if you exercise. Ask your doctor to recommend an exercise program for you. Try to reduce the stress in your life and get plenty of sleep. If you smoke, quit! If you are overweight, talk to your doctor about how to lose weight safely.
Also talk to your doctor before you take any medicine. Common arthritis medicines like naproxen and ibuprofen can cause fluid retention.
Fluid retention and weight gain are one signal that your CHF may not be in good control. Weigh yourself daily at the same time of day and report any unexplained changes to your doctor.
