Physical Examination

Your doctor will ask you about your symptoms, family history and risk factors. He or she will ask specific questions about your chest pain, asking you to describe it in detail.

Diagnostic Tests

If your doctor thinks you have coronary artery disease, he or she will probably do one or more of the following tests.

If you go to the emergency room with chest pain, some of the following tests will be ordered immediately. These tests will determine if you are having angina or a heart attack. If you have a stable pattern of angina, other tests may be done to determine the severity of your disease. If your doctor thinks you have coronary artery disease (CAD), he or she will probably do one or more of the following tests:

Blood Tests

These tests check for levels of certain fats, cholesterol, sugar and proteins called troponins in the blood that help determine if you have risk factors for coronary artery disease or if you are having a heart attack.

ECG/EKG WavesElectrocardiogram (EKG or ECG)

This is a painless, noninvasive test in which patches with electrodes are attached to your skin to measure electrical impulses produced by your heart.

These impulses are recorded as waves displayed on a monitor or printed out on graph paper. The test can reveal evidence of a previous heart attack or one that is in progress. Heart rhythm is also captured with an EKG.

Holter Monitor

This is a portable device that records all of your heartbeats over an extended period, usually either 24 or 48 hours. You wear small patches with electrodes on your chest that are connected by wires to a small, portable recorder. The recorder can be clipped to a belt, kept in a pocket, or hung around your neck. During the time you're wearing a Holter monitor, you do your usual daily activities. This is used to monitor heart rhythm for an extended period of time.


This test uses sound waves to create a moving picture of your heart.

  • Provides information about the size and shape of your heart and how well your heart chambers and valves are functioning.
  • Identifies areas of poor blood flow to the heart, areas of heart muscle that aren't contracting normally, and previous injury to the heart muscle caused by poor blood flow.

The test is noninvasive and is performed by placing a probe on your chest wall. It is the same technique used in sonograms in pregnant women.

Stress Test

During a stress test, you exercise to make your heart work harder and beat faster. An EKG is recorded and blood pressure is monitored during exercise. The technician will be asking you about the presence of symptoms such as chest pain or shortness of breath.

Sometimes imaging is also done. This can be done with an echocardiogram as described above or by using a radioactive dye and xray equipment to image the heart's motion with exercise. If imaging is performed with your stress test, resting images (without exercise) are compared to stress images (after exercise) to look for changes in heart function that are related to blood flow patterns.

Coronary Angiogram or Catheterization

To directly see the pattern of blood flow in your arteries, your doctor may want to perform a coronary catheterization. This involves injecting a dye into your arteries in what is called an angiogram.

The dye is delivered through a long, thin, flexible tube called a catheter that is threaded through a leg artery into the coronary arteries. This is called catheterization.

AngiographyThe dye outlines areas of blockages on x-ray images. If a blockage is found and needs treatment, a balloon can be pushed through the catheter and inflated to open the artery or arteries in question. A stent or tiny wire mesh tube can then be inserted to keep the artery open.

This procedure is done in the hospital.

CT Scan

A computerized tomography (CT) scan uses X-rays and computers to get detailed pictures of the body. Coronary artery calcification CT scans can detect calcium in the coronary arteries which may indicate the presence of coronary artery disease. A CT coronary angiogram uses x-ray dye (contrast) to look at blood flow patterns within the coronary arteries to detect blockages. This provides information similar to the catheter based angiogram, above, but is not as invasive.
