Congestive Heart Failure

Congestive heart failure (CHF), or heart failure, is a condition in which the heart can't pump enough blood to the body's other organs. This can result from

The "failing" heart keeps working but not as efficiently as it should. People with heart failure can't exert themselves because they become short of breath and tired.

As blood flow out of the heart slows, blood returning to the heart through the veins backs up, causing congestion in the tissues. Often swelling (edema) results. Most often there's swelling in the legs and ankles, but it can happen in other parts of the body, too. Sometimes fluid collects in the lungs and interferes with breathing, causing shortness ofbreath, especially when a person is lying down.

Heart failure also affects the kidneys' ability to dispose of sodium and water. The retained water increases the edema.

How do you diagnose and treat congestive heart failure?

Your doctor is the best person to make the diagnosis. The most common signs of congestive heart failure are swollen legs or ankles or difficulty breathing. Another symptom is weight gain when fluid builds up.

CHF usually requires a treatment program of

Various drugs are used to treat congestive heart failure. They perform different functions. ACE inhibitors and vasodilators expand blood vessels and decrease resistance. This allows blood to flow more easily and makes the heart's work easier or more efficient. Beta blockers can improve how well the heart's left lower chamber (left ventricle) pumps. Digitalis increases the pumping action of the heart, while diuretics help the body eliminate excess salt and water.

When a specific cause of congestive heart failure is'discovered, it should be treated or, if possible, corrected. For example, some cases congestive heart failure can be treated by treating high blood pressure. If the heart failure is caused by an abnormal heart valve, the valve can be surgically replaced.

If the heart becomes so damaged that it can't be repaired, a more drastic approach should be considered. A heart transplant could be an option.

Most people with mild and moderate congestive heart failure can be treated. Proper medical supervision can prevent them from becoming invalids.

How Is Heart Failure Treated?

Heart failure can be treated but usually cannot be cured. The cornerstones of treatment are medications and lifestyle changes. The body is designed to react to sudden emergencies, such as an attack or blood loss, by activating reflexes that make the heart pump harder and faster and fill up with more fluid. These reflexes remain turned on in chronic heart failure, increasing the load on the injured heart and weakening it further. The major medications for heart failure can counteract these reflexes and help the heart work more efficiently.

What Can I Expect?

The outlook for patients with heart failure continues to improve. People are feeling better and living longer. Heart failure is a chronic disease. For the rest of your life, you will need to follow a personalized program of medications and lifestyle. There will be good days and bad days for you as there are for everyone. The goal is to live as fully as possible.
