Electron Beam Computerized Tomography (cont.)

What Can I Expect During a Heart CT Scan?

During the CT scan of your heart:

  • You will change into a hospital gown. The nurse will record your height, weight, and blood pressure. He or she may draw your blood for a lipid analysis.
  • You will lie on a special scanning table.
  • The technologist will clean three small areas of your chest and place small, sticky electrode patches on these areas. Men may expect to have their chest partially shaved to help the electrodes stick. The electrodes are attached to an electrocardiograph (ECG) monitor, which charts your heart's electrical activity during the test.
  • You may also be given an injection of a contrast material to help the CT scanner directly visualize your coronary arteries.
  • During the scan, you will feel the table move inside a donut-shaped scanner. The high-speed CT scan captures multiple images, synchronized with your heartbeat.
  • A sophisticated computer program, guided by the cardiovascular radiologist, analyzes the images for presence of calcification within the coronary arteries. Absence of calcium is considered a "negative" exam. But, it does not exclude the presence of "soft" noncalcified plaque. If calcium is present, the computer will create a calcium "score" that estimates the extent of coronary artery disease.
  • The calcium-score screening heart scan takes only a few minutes.

What Happens After a Heart CT Scan?

You may continue all normal activities and eat as usual after the heart CT scan.

The results of the scan will be reviewed. The following information will be obtained:

  • The number and density of calcified coronary plaques in the coronary arteries.
  • Calcium score.

Your heart CT scan results will be examined and reviewed by a team of cardiovascular specialists, including a cardiovascular radiologist and a preventive cardiologist. The team will evaluate the calcium score and/or your CT angiogram, along with other risk factor measurements (risk factor evaluation, blood pressure, lipid analysis), to determine your risk for future coronary artery disease and will make recommendations regarding your lifestyle, medications, or additional cardiac testing.

You and your primary care doctor will receive the full report outlining your risk assessment and follow-up recommendations. Ask your doctor if you have any questions about the calcium-score screening heart scan.
