How is congestive heart failure diagnosed?
Congestive heart failure is a clinical diagnosis. The symptoms described above are important clues to the problem. A good physical examination is of major importance. Doctors can usually make a diagnosis of congestive heart failure based upon a physical exam and the symptoms alone. During the physical exam, the doctor will check for a weak or rapid pulse rate, enlargement of the heart, swollen neck veins, swelling of the liver, fluid retention, sounds of fluid in the lungs, and abnormal
heart sounds. To confirm the diagnosis, he or she may perform a number of tests, including chest x-rays, blood tests, 12-lead electrocardiograms (EKGs), urinalysis, and exercise stress tests. Tests such as electrocardiograms, echocardiograms, and angiography create images of the heart's activity and are also helpful in the diagnosis.
Congestive heart failure is easily confused with other illnesses that cause breathing difficulties, such as bronchitis, pneumonia, emphysema, and asthma. Talking to a medical professional, along with a physical exam and tests available only at a medical office or hospital, is necessary to make an exact diagnosis. When symptoms suggest congestive heart failure, the diagnosis usually is confirmed by physical examination, patient history, and various tests to detect abnormal function of the left ventricle and/or heart valves. When symptoms suggest congestive heart failure, the diagnosis usually is confirmed by physical examination, patient history, and various tests to detect abnormal function of the left ventricle and/or heart valves.
During physical examination, the physician looks for an underlying cause and assesses heart function. A stethoscope is used to detect abnormal heart sounds (murmurs) that may indicate a leaky or narrowed (stenotic) valve, and to detect fluid accumulation in the lungs. The physician also looks for enlarged (distended) veins in the neck and for swelling (edema) in the legs (particularly the ankles and feet) and/or the abdomen.
Useful diagnostic tests include the electrocardiogram (ECG) and chest x-ray to explore the possibility of previous heart attacks, arrhythmia, heart enlargement, and fluid in and around the lungs. Perhaps the single most useful diagnostic test is the echocardiogram, in which ultrasound is used to image the heart muscle, valvular structures, and blood flow patterns. The echocardiogram is very helpful in diagnosing heart muscle weakness. In addition, the test can suggest possible causes for the heart muscle weakness (e.g., prior heart attack, severe valvular abnormalities). Virtually all patients in whom the diagnosis of congestive heart failureF is suspected should ideally undergo echocardiography at some point.
