Heart failure is often a long-term (chronic) condition, but it may come on suddenly. It can be caused by many different heart problems.

The condition may affect only the right side or only the left side of the heart. More often, both sides of the heart are involved.

Heart failure is present when:

• Your heart muscle cannot pump (eject) the blood out of the heart very well. This is called systolic heart failure.
• Your heart muscles are stiff and do not fill up with blood easily. This is called diastolic heart failure.

As the heart's pumping becomes less effective, blood may back up in other areas of the body. Fluid may build up in the lungs, liver, gastrointestinal tract, and the arms and legs. This is called congestive heart failure.

The most common causes of heart failure are:

• Coronary artery disease (CADきゃど), a narrowing of the small blood vessels that supply blood and oxygen to the heart. This can weaken the heart muscle over time or suddenly.
• High blood pressure that is not well controlled, leading to problems with stiffness, or eventually leading to muscle weakening.

Other heart problems that may cause heart failure are:

• Congenital heart disease
• Heart attack
• Heart valves that are leaky or narrowed)
• Infection that weakens the heart muscle
• Some types of abnormal heart rhythms (arrhythmias)

Other diseases that can cause or contribute to heart failure:

• Amyloidosis
• Emphysema
• Overactive thyroid
• Sarcoidosis
• Severe anemia
• Too much iron in the body
• Underactive thyroid

Back to TopSymptoms »

Symptoms of heart failure often begin slowly. At first, they may only occur when you are very active. Over time, you may notice breathing problems and other symptoms even when you are resting. Symptoms may also appear suddenly after the heart is damaged from a heart attack or other problem.

Common symptoms are:

• Cough
• Fatigue, weakness, faintness
• Loss of appetite
• Need to urinate at night
• Pulse that feels fast or irregular, or a sensation of feeling the heart beat (palpitations)
• Shortness of breath when you are active or after you lie down
• Swollen (enlarged) liver or abdomen
• Swollen feet and ankles
• Waking up from sleep after a couple of hours due to shortness of breath
• Weight gain

MONITORING AND SELF CARE

If you have heart failure, your doctor will monitor you closely. You will have follow-up appointments at least every 3 to 6 months, but sometimes much more often. You will also have tests to check your heart function.

Knowing your body and the symptoms that your heart failure is getting worse will help you stay healthier and out of the hospital. At home, watch for changes in your heart rate, pulse, blood pressure, and weight.

Weight gain, especially over a day or two, can be a sign that your body is holding onto extra fluid and your heart failure is getting worse. Talk to your doctor about what you should do if your weight goes up or you develop more symptoms.

Limit how much salt you eat. Your doctor may also ask you to limit how much fluid you drink during the day.

Other important changes to make in your lifestyle:

• Ask your doctor how much alcohol you may drink.
• Do not smoke.
• Stay active. Walk or ride a stationary bicycle. Your doctor can provide a safe and effective exercise plan for you. Do not exercise on days when your weight has gone up from fluid or you are not feeling well.
• Lose weight if you are overweight.
• Lower your cholesterol by changing your lifestyle.
• Get enough rest, including after exercise, eating, or other activities. This allows your heart to rest too.

MEDICATIONS, SURGERY, AND DEVICES

Your doctor will ask you to take medicines to treat your heart failure. Medicines treat the symptoms, prevent your heart failure from getting worse, and help you live longer. It is very important that you take your medicine as your health care team directed.

These medicines:

• Help the heart muscle pump better
• Keep your blood from clotting
• Lower your cholesterol levels
• Open up blood vessels or slow your heart rate so your heart doesn't have to work as hard
• Reduce damage to the heart
• Reduce the risk of abnormal heart rhythms
• Replace potassium
• Rid your body of excess fluid and salt (sodium)

It is very important that you take your medicine as your doctor and nurse directed. Do not take any other drugs or herbs without first asking your doctor or nurse about them. Drugs that may make your heart failure worse include:

• Ibuprofen (Advil, Motrin)
• Naproxen (Aleve, Naprosyn)

The following surgeries and devices for certain patients with heart failure may be recommended:

• Coronary bypass surgery (CABG) or angioplasty with or without stenting may help improve blood flow to the damaged or weakened heart muscle.
• Heart valve surgery may be done if changes in a heart valve are causing your heart failure.
• A pacemaker can help treat slow heart rates or help both sides of your heart contract at the same time.
• A defibrillator sends an electrical pulse to stop life-threatening abnormal heart rhythms.

END-STAGE HEART FAILURE

Severe heart failure occurs when treatments no longer work. Certain treatments may be used when a person is waiting for a heart transplant:

• Intra-aortic balloon pump (IABP)
• Left ventricular assist device (LVAD)

At a certain point, the health care provider will decide whether it is best to keep treating heart failure aggressively. The patient, along with his or her family and doctors, may want to discuss palliative or comfort care at this time.

Most cases of heart failure can be prevented by living a healthy lifestyle and reducing your risk for heart disease
