Ashd (atherosclerotic heart disease) Evaluation

The evaluation of coronary artery disease begins with a medical history and physical examination.

Physical findings in someone with coronary artery disease may include:


Testing is necessary to confirm the diagnosis of coronary artery disease.

Tests that may be used to evaluate coronary artery disease include:

Other tests that may be used to evaluate coronary artery disease include:

Ashd (atherosclerotic heart disease) Electrocardiogram

An electrocardiogram or ECG can be an effective tool in detecting coronary artery disease.

How an ECG Works
An electrical impulse stimulates the muscle fibers in the heart to contract. The impulse spreads through the heart in a very organized manner. The heart's normal electrical impulse has a characteristic pattern. The EKG machine displays the pattern of the electrical impulse.

Abnormal electrical patterns on the EKG can help identify heart disease.

The EKG can identify:

Ashd (atherosclerotic heart disease) Heart Catheterization

Cardiac catheterization and coronary angiogram are effective tools for detecting coronary artery disease.

How Heart Catheterization Works
During a cardiac catheterization, a catheter (thin plastic tube) is inserted into an artery in the groin, and then threaded up through the aorta to the heart. The catheter can be used to inject x-ray dye into the coronary arteries that supply the heart. An x-ray machine is used to take pictures of the dye inside the coronary arteries. This procedure is referred to as coronary angiography. Using these procedures doctors can detecting narrowing or obstruction of the coronary arteries.

Examples include:

Ashd (atherosclerotic heart disease) Thallium Stress Test

Thallium stress testing is an effective tool for detecting coronary artery disease.

How Thallium Stress Testing Works
The thallium stress test identifies areas of the heart muscle that receive reduced blood flow from narrowed or blocked coronary arteries. During the test, thallium is injected into the bloodstream. Heart muscle cells collect the thallium in the bloodstream. If blood flow is reduced through one of the coronary arteries, then the muscle cells that are supplied by that artery do not collect as much thallium as muscle cells that receive normal blood flow. A special camera is used to detect thallium in the heart muscle and a computer constructs images of the heart. The images show areas that receive reduced blood flow.
