Diagnosis & Tests
Tell your healthcare provider if you have any heart failure symptoms. Especially if you’ve already been diagnosed with high blood pressure or coronary artery disease, or have had a heart attack.
By examining you, your healthcare provider may be able to tell if your heart isn’t pumping well or if you have fluid buildup. They will listen to your heart and lungs, feel your liver to see if it’s enlarged, or look at the veins in your neck to see if they are bulging.
You will probably need additional tests to confirm the type and severity of your heart failure, and to decide the best treatments. These may include a variety of blood and urine tests and some common heart tests.
A chest x-ray can show whether parts of your heart are enlarged, or if there is fluid buildup in your lungs. These can be signs of heart failure, a heart valve problem, or thickening of the heart muscle.
Echocardiogram (or “Echo”) and Echo Stress Test
This is the most common test for heart function, heart valve problems, and other heart conditions. It uses ultrasound (sound waves) to create a picture of the inside of your heart while it’s beating. This test is often done while you’re on a treadmill or exercise bicycle to see how your heart pumps during exercise.
Electrocardiogram (ECG or EKG) and ECG Stress Test
This simple, painless test measures the electrical activity of your heart. It uses electrodes (wires) placed on the chest and other parts of your body. You might have the test while you are lying down, or while you are exercising on a treadmill or bicycle, to see how your heart responds to increased physical activity. If you can’t exercise, your health care provider might give you a medication to make your heart pump harder.
CT Coronary Angiogram
This special x-ray is used to show your heart and the arteries that bring blood to your heart muscleIf you have this test, you will be exposed to some radiation, have an injection of dye, and possibly take a dose of a medication that slows your heart slightly.
There are differences between a regular angiogram and a CT angiogram. During a regular angiogram, a catheter is placed through a blood vessel into your heart. If a blockage is found in an artery during a regular angiogram, the heart specialist can treat it right then with a treatment called angioplasty. This treatment is not possible during a CT angiogram.
Nuclear Stress Test
If you have chest pain or shortness of breath, your healthcare provider may order a test called a nuclear stress test. You will receive an injection of radioactive dye and pictures will be taken of your heart while you are at rest. Afterwards, you may be asked to exercise on a treadmill or stationary bicycle, or you may receive an injection to speed up your heart. Another injection of radioactive dye may be given during the test and your blood pressure and heartbeat (ECG) will be monitored during the test. More pictures of your heart will be taken while you are exercising. After resting for a certain amount of time you might have another set of pictures taken.
A specialist will read the pictures from the nuclear stress test. These pictures will show if there are any damaged areas in your heart. They may also show whether the arteries that bring blood to your heart muscle are blocked or narrowed, or if your heart is enlarged. Finally, it measures how well your heart is pumping blood (this is called the ejection fraction).
