- Is a Complete Workup Needed When a Diagnosis is Already Worked Out?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: My increasing difficulty with breathing has been finally diagnosed
- as "congestive heart failure". Now I face a whole bunch of tests and am
- worried that perhaps much of this is unnecessary, and even expensive. Do you
- think that a complete workup is needed when the diagnosis is already worked
- out?
-

- ANSWER: Not only are your doctor's tests necessary, they may be critical in
- pinpointing your actual condition and saving your life. Congestive heart
- failure (CHF) can take either of two forms: a reduced level of cardiac
- performance not capable of meeting the needs of your body, or hypertension
- resulting from the after effects of a heart attack or chronic salt and water
- retention.
- Chest radiography--standard x-rays--can uncover signs of hypertension and
- measure the amount of fluid retention taking place in the chest. The size and
- silhouette of the heart itself can be studied on the x-rays in order to
- diagnose specific types of heart disease.
- Echocardiography uses sound waves to analyze the heart's function,
- particularly in cases where the organ is performing poorly. The activity
- within the different chambers of the heart can be studied individually,
- pinpointing the site of reduced function. The technology allows the doctor to
- compare the heart while pumping and at rest to determine its "ejection
- fraction," (which tells how much of the blood in the heart has been pumped out
- to the body); with a lower than normal reading indicating that your heart has
- become weakened.
- Refinements of the craft include two-dimensional echocardiography, in
- which the ultrasound beam reveals a cross-section of the heart's activity, and
- doppler echocardiography to learn the blood flow rate. (Previously, a
- catheter had to be inserted into the heart to determine these findings).
- Based on his or her preliminary findings, your doctor will determine which
- tests are appropriate to your situation. While follow-up tests may be called
- for to clarify a difficult diagnosis, they serve one purpose: to eliminate
- any doubt as to your best course of treatment, and help assure your recovery.
