Congestive Heart Failure

Congestive Heart Failure: Introduction

Congestive heart failure, or CHF, is a very serious condition in which the heart muscle has been damaged. Although the heart continues to beat in congestive heart failure, it is too weak to efficiently pump enough oxygen-rich blood to and from the lungs and the rest of the body. Congestive heart failure is a common complication of heart attack and other types of heart diseases and cardiovascular diseases that damage the heart muscle. These include hypertension, heart valve disorders, arrhythmias, and cardiomyopathy. Congestive heart failure can also result from anemia.

Any disease or condition that increases the risk of developing heart disease or cardiovascular disease also increases the risk of eventually developing congestive heart failure as a complication. These risks include having diabetes, high cholesterol, obesity, and a sedentary lifestyle. Other risk factors include being male, of African-American ancestry, and drinking excessive amounts of alcohol. Having a lot of long-term stress, smoking and having a family history of heart disease or cardiovascular disease are also risk factors.

There are two types of congestive heart failure. In left-sided congestive heart failure, the heart is not able to pump blood effectively out to the body, which results in blood backing up into the veins that carry blood from the lungs to the heart. This increases blood pressure in the lungs and leads to the accumulation of fluid in the lungs. This is called pulmonary edema and is a very serious condition, which can be fatal. Symptoms include shortness of breath, chest pain, cough, and low oxygen levels in the blood.

In right-sided congestive heart failure, the weak pumping of the heart allows blood to back up in the veins that lead from the body to the heart. This leads to swelling of the lower extremities (edema) and other symptoms. For more information on symptoms and complications, refer to symptoms of congestive heart failure.

Making a diagnosis of congestive heart failure includes a complete medical evaluation, medical history and physical examination. If symptoms are acute and severe, this is often done in an emergency room. The physical exam includes listening to the sounds of the heart and the lungs with a stethoscope. Certain sounds, such as a crackling or bubbling sound on the lungs, indicate congestion in the lungs and may point to a diagnosis of congestive heart failure.

A chest X-ray is generally performed to see the size and shape of the heart and can reveal lung congestion and other conditions, such as pneumonia. Other tests may include an echocardiogram, which can evaluate the heart valves and determine how much blood the heart is able to pump.

Other testing may be done to rule-out or diagnose underlying causes of congestive heart failure or other conditions that can mimic congestive heart failure. For example, testing generally includes an EKG, which takes a picture of the electrical activity of the heart and can reveal abnormalities in the rhythm of the heart and damage done to the heart due to heart attack and some other forms of heart disease. A coronary angiogram may also be performed to look for blocked coronary arteries.

It is possible that a diagnosis of congestive heart failure can be missed or delayed because the symptoms may develop gradually, be mild and can be similar to symptoms of other conditions. For more information about misdiagnosis and diseases and conditions that can mimic congestive heart failure, refer to misdiagnosis of congestive heart failure.

Treatment of congestive heart failure can include lifestyle and dietary changes, medications, and heart transplant in some cases. For more information on treatment, refer to treatment of congestive heart failure. ...more »

Facts About Heart Failure in Older Adults: CDC-OC (Excerpt)

Congestive heart failure is a major chronic disease for older adults, accounting for about 260,000 deaths a year. The majority of the nearly 5 million U.S. patients with heart failure are older than 65 years. In 1995, $3.4 billion was paid by Medicare for heart failure. As the "baby boomers" age during the next 40 years, the number of heart failure patients older than 65 is expected to double. (Source: excerpt from Facts About Heart Failure in Older Adults: CDC-OC)
