Managing Congestive Heart Failure

What is Congestive Heart Failure (CHF)?

CHF is a condition in which the heart cannot (fails to) pump enough blood to organs and tissues. One side of the heart (or both sides) cannot force enough blood out, so blood backs up. Congestion, or abnormal build up of fluid, occurs in tissues or organs, and blood doesn't move well through the vascular system.

If the left side of the heart fails, the system on the right side becomes congested. The congested side of the heart must work harder and may also fail. The same thing can happen on the right side.

What Causes CHF?

Diseases that stress heart muscle can cause CHF. These conditions include high blood pressure, heart attack, heart muscle and valve diseases, infections, arrhythmias (abnormal heart rhythms), anemia, thyroid disease, pulmonary disease, and too much fluid in the body.

What are the Symptoms of CHF?

In the left side of the heart fails, fluid leaks into the lungs. Fatigue (tiredness), difficulty breathing (especially at night when lying down), coughing, or shortness of breath can result.

In right-side heart heart failure, the liver swells, which may cause pain in the abdomen (belly). Legs and feet may swell also.

How is CHF Diagnosed?

A physical examination will show changes, such as swelling in the legs or crackling breath sounds, indicating excess fluid in the lungs. A chest x-ray can show an enlarged heart and signs of fluid accumulation into the lungs. An echocardiogram (a test using sound waves to show the moving heart) can also reveal heart size and disease of the heart muscle or valve problems.

How is CHF Treated?

Initial symptoms should be managed so the failing heart doesn't have to work as hard.

The cause of CHF also needs treatment. For example, if a heart valve problem is the cause, surgery may be needed to repair or replace the valve. Lifestyle changes will be needed. Smoking lowers the blood oxygen level and makes the heart work harder, so avoid tobacco. Less fluid and salt in the diet reduces fluid in the body. Also, losing weight will help. Dietitians and nutritionists can help plan a diet.

Oxygen may be given to reduce the workload on the lungs.

Medicines may be prescribed to reduce fluid in the body or help the ventricle contract better. Diuretics remove fluid. Nitrates open blood vessels so blood flows more easily. Angiotensin-converting enzyme (ACE) inhibitors help the ventricle contract. Beta-blockers help by slowing the heart rate. Other drugs reduce blood pressure. All may have side effects, including dehydration, cough, dizziness, fainting, and fatigue.

DOs and DON'Ts in Managing Heart Failure:

  • DO take your medicines properly.
  • DO maintain your ideal body weight.
  • DO reduce salt and extra fluid in your diet.
  • DO get your family involved in your care, especially the needed lifestyle changes.
  • DO call your doctor if you have side effects from your drugs or new or worsening symptoms, such as increasing shortness of breath, chest pain, or fainting.
  • DON'T forget to take all your medicines as directed.
  • DON'T smoke.
  • DON'T stop taking any medicines without telling your doctor.
