Heart Failure

What is heart failure?

Heart failure, also called congestive heart failure, is a condition in which the heart cannot pump enough oxygenated blood to meet the needs of the body's other organs. The heart keeps pumping, but not as efficiently as a healthy heart. Usually, the heart's diminished capacity to pump reflects a progressive, underlying condition.

What causes heart failure?

Heart failure may result from any or all of the following:

  • Heart valve disease caused by past rheumatic fever or other infections
  • High blood pressure (hypertension)
  • Active infections of the heart valves and/or heart muscle (for example, endocarditis or myocarditis)
  • Previous heart attack(s) (myocardial infarction). Scar tissue from prior damage may interfere with the heart muscle's ability to pump normally.
  • Coronary artery disease. Narrowing of the arteries that supply blood to the heart muscle.
  • Cardiomyopathy or another primary disease of the heart muscle
  • Congenital heart disease or defects (present at birth)
  • Cardiac arrhythmias (irregular heartbeats)
  • Chronic lung disease and pulmonary embolism
  • Certain medications
  • Excessive sodium (salt) intake
  • Anemia and excessive blood loss
  • Complications of diabetes

How does heart failure affect the body?

Heart failure interferes with the kidney's normal function of eliminating excess sodium and waste products from the body. In congestive heart failure, the body retains more fluid, resulting in swelling of the ankles and legs. Fluid also collects in the lungs, which can cause profound shortness of breath.

What are the symptoms of heart failure?

The following are the most common symptoms of heart failure. However, each individual may experience symptoms differently. Symptoms may include:

  • Shortness of breath during rest, exercise, or while lying flat
  • Weight gain
  • Visible swelling of the legs and ankles (due to a buildup of fluid), and, occasionally, swelling of the abdomen
  • Fatigue and weakness
  • Loss of appetite, nausea, and abdominal pain
  • Persistent cough that can cause blood-tinged sputum

The severity of the condition and symptoms depends on how much of the heart's pumping capacity has been compromised.

The symptoms of heart failure may resemble other conditions or medical problems. Always consult your health care provider for a diagnosis.

How is heart failure diagnosed?

In addition to a complete medical history and physical examination, diagnostic procedures for heart failure may include any, or a combination of, the following:

  • Chest X-ray. A diagnostic test that uses invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs onto film.
  • Echocardiogram (also called echo). A noninvasive test that uses sound waves to evaluate the motion of the heart's chambers and valves. The echo sound waves create an image on the monitor as an ultrasound transducer is passed over the heart.
  • Electrocardiogram (ECG or EKG). A test that records the electrical activity of the heart, shows abnormal rhythms (arrhythmias or dysrhythmias), and can sometimes detect heart muscle damage.
  • BNP testing. B-type natriuretic peptide (BNP) is a hormone released from the ventricles in response to increased wall tension (stress) that occurs with heart failure. BNP levels rise as wall stress increases. BNP levels are useful in the rapid evaluation of heart failure. In general, the higher the BNP levels, the worse the heart failure.


Treatment for heart failure

Specific treatment for heart failure will be determined by your health care provider based on:

  • Your age, overall health, and medical history
  • Extent of the disease
  • Your tolerance for specific medications, procedures, or therapies
  • Expectations for the course of the disease
  • Your opinion or preference

The cause of the heart failure will dictate the treatment protocol established. If the heart failure is caused by a valve disorder, then surgery may be performed. If the heart failure is caused by a disease, such as anemia, then the underlying disease will be treated. Although there is no cure for heart failure due to damaged heart muscle, many forms of treatment have been used to treat symptoms very effectively.

The goal of treatment is to improve a person's quality of life by making the appropriate lifestyle changes and implementing drug therapy.

Treatment of heart failure may include:

  • Controlling risk factors:
    • Quitting smoking
    • Losing weight (if overweight) and increasing moderate exercise
    • Restrict salt and fat from the diet
    • Avoiding alcohol
    • Proper rest
    • Controlling blood sugar if diabetic
    • Controlling blood pressure
    • Limiting fluids
  • Medication, such as:
    • Angiotensin converting enzyme (ACE) inhibitors. This medication decreases the pressure inside the blood vessels and reduces the resistance against which the heart pumps.
    • Angiotensin receptor blockers (ARB). This is alternative medication for reducing workload on the heart if ACE inhibitors are not tolerated.
    • Diuretics. These reduce the amount of fluid in the body.
    • Vasodilators. These dilate the blood vessels and reduce workload on the heart.
    • Digitalis. This medication helps the heart beat stronger with a more regular rhythm.
    • Antiarrhythmia medications. These help maintain normal heart rhythm and help prevent sudden cardiac death.
    • Beta-blockers. These reduce the heart's tendency to beat faster and reduce workload by blocking specific receptors on heart cells.
    • Aldosterone blockers. Medication that blocks the effects of the hormone aldosterone which causes sodium and water retention.
  • Biventricular pacing/cardiac resynchronization therapy. A new type of pacemaker that paces both pumping chambers of the heart simultaneously to coordinate contractions and to improve the heart's function. Some heart failure patients are candidates for this therapy.
  • Implantable cardioverter defibrillator. A device similar to a pacemaker that senses when the heart is beating too fast and delivers an electrical shock to convert the fast rhythm to a normal rhythm.
  • Heart transplantation
  • Ventricular assist devices (VADs). These are mechanical devices used to take over the pumping function for one or both of the heart's ventricles, or pumping chambers. A VAD may be necessary when heart failure progresses to the point that medications and other treatments are no longer effective.
