Heart failure - tests
CHF - tests; Congestive heart failure - tests; Cardiomyopathy - tests; HF - testsThe diagnosis of heart failure is made largely on a person's symptoms and a physical exam. However, there are many tests that can help give more information about the condition.
Echocardiogram
An echocardiogram (cardiac echo) is a test that uses sound waves to create a moving picture of the heart. The picture is much more detailed than a plain x-ray image.

Read Article Now Book Mark ArticleThis test helps your health care provider learn more about how well your heart contracts and relaxes. It also provides information about the size of your heart and how well the heart valves are working.
An echocardiogram is the best test to:
- Identify which type of heart failure (systolic, diastolic, valvular)
- Monitor your heart failure and guide your treatment
Heart failure can be diagnosed if the echocardiogram shows that the pumping function of the heart is too low. This is called an ejection fraction. A normal ejection fraction is 55% to 65%.
If only some parts of the heart are not working correctly, it may mean that there is a blockage in the artery of the heart that delivers blood to that area.
Other Imaging Tests
Many other imaging tests are used to look at how well your heart is able to pump blood and the extent of heart muscle damage.
You may have a chest x-ray done in your provider's office if your symptoms suddenly become worse. However, a chest x-ray cannot diagnose heart failure.
x-ray
A chest x-ray is an x-ray of the chest, lungs, heart, large arteries, ribs, and diaphragm.
Read Article Now Book Mark ArticleVentriculography is another test that measures the overall squeezing strength of the heart (ejection fraction). Like an echocardiogram, it can show parts of the heart muscle that are not moving well. This test uses x-ray contrast fluid to fill the pumping chamber of the heart and evaluate its function. It is often done at the same time as other tests, such as coronary angiography.
Ventriculography
Nuclear ventriculography is a test that uses radioactive materials called tracers to show the heart chambers. The procedure is noninvasive. The ins...

Your provider may order a heart catheterization if any imaging tests suggest that you have narrowing in one of your arteries, or if you are having chest pain (angina) or a more definitive test is desired.

Several different blood tests can be used to learn more about your condition. Tests are done to:
- Help diagnose the cause for and monitor heart failure.
- Identify risk factors for heart disease.
- Look for possible causes of heart failure or problems that may make your heart failure worse.
- Monitor side effects of medicines you may be taking.
Blood urea nitrogen (BUN) and serum creatinine tests help monitor how well your kidneys are working. You will need these tests regularly if:

Sodium and potassium levels in your blood will need to be measured on a regular basis when there are changes made for some medicines including:
Sodium
The sodium blood test measures the concentration of sodium in the blood. Sodium can also be measured using a urine test.

Anemia, or low red blood cell count, can make your heart failure worse. Your provider will check your CBC or complete blood count on a regular basis or when your symptoms become worse.

A complete blood count (CBC) test measures the following:The number of white blood cells (WBC count)The number of red blood cells (RBC count)The numb...
