Heart Scans

Heart Scan (Coronary Calcium Scan)

A heart scan, also known as a coronary calcium scan, is a specialized X-ray test that provides pictures of your heart that can help your doctor detect and measure calcium-containing plaque in the arteries.

Plaque inside the arteries of your heart can grow and restrict blood flow to the muscles of the heart. Measuring calcified plaque with a heart scan may allow your doctor to identify possible coronary artery disease before you have signs and symptoms.

Your doctor will use your test results to determine if you may need medication or lifestyle changes to reduce the risk of heart attack or other heart problems.

Why it’s done

Your doctor may order a heart scan to get a better understanding of your risk of heart disease or if your treatment plan is uncertain.

A heart scan uses a specialized X-ray technology called multidetector row or multislice computerized tomography (CT), which creates multiple images of plaque deposits in the blood vessels. The imaging test provides an early look at levels of plaque.

Plaque is made up of fats, cholesterol, calcium and other substances in the blood. It develops gradually over time, long before there are any signs or symptoms of disease. These deposits can restrict the flow of oxygen-rich blood to the muscles of the heart. Plaque also may burst, triggering a blood clot that can cause a heart attack.

This is a painless procedure!

When is a heart scan used?

A heart scan may help guide treatment if you have a low to moderate risk of heart disease or if your heart disease risk isn’t clear. Your doctor can tell you if you might benefit from having a heart scan based on your risk factors.

A heart scan also may help motivate people at moderate risk to make important lifestyle changes and follow treatment plans.

When is a heart scan not used?

A heart scan requires exposure to radiation. While the exposure is generally considered safe, the scan isn’t recommended if the risk of radiation exposure outweighs any potential benefit.

According to the American College of Cardiology and the American Heart Association guidelines, a heart scan may not be recommended for the following people:

  • Men under age 40 and women under age 50, because it’s unlikely calcium can be detected at younger ages
  • People who have a very low risk, because detectable calcium is highly unlikely if you don’t have a family history of heart attacks at an early age
  • People who already have a known high risk (especially heavy smokers or those with diabetes or very high cholesterol), because the heart scan will likely not provide any additional information to guide treatment
  • People with symptoms or a diagnosis of coronary artery disease, because the procedure won’t help doctors better understand the disease progression or risk
  • People who already had an abnormal coronary calcium heart scan

How you prepare

Food and medications

  • You may be asked to avoid caffeine and smoking for four hours before the test
  • You should avoid taking Cialis/Viagra 12 hours prior to scan
  • No fasting is necessary

Clothing and personal items

When you arrive for the procedure, please check in at Rio Grande Hospital’s front desk. Once in radiology, you will be asked to remove clothing above the waist and to wear a medical gown. You will also need to remove jewelry around your neck or near your chest.

What you can expect

During the procedure

Before the scan begins, the technologist attaches sensors, called electrodes, to your chest. These connect to an electrocardiogram (ECG or EKG), which records your heart activity during the exam and coordinates the timing of X-ray pictures between heartbeats, when the heart muscles are relaxed.

During the heart scan, you lie on your back on a movable table, which slides into the tubelike CT scanner. Your head is outside the scanner the whole time. The exam room will likely be cool.

You’ll be asked to lie still and hold your breath for a few seconds while the pictures are taken. The technologist operates the scanner from a room next door, but can see and talk to you the entire time. The entire procedure should take about 10 to 15 minutes.

After the procedure

Usually, no special precautions are needed after having a heart scan. You will be able to drive yourself home and continue your daily activities.

Results

The result of the test is usually given as a number called an Agatston score. The score reflects the total area of calcium deposits and the density of the calcium.

  • A score of zero means no calcium is seen in the heart. It suggests a low chance of developing a heart attack in the future.
  • When calcium is present, the higher the score, the higher your risk of heart disease.
  • A score of 100 to 300 means moderate plaque deposits. It’s associated with a relatively high risk of heart attack or other heart disease over the next three to five years.
  • A score greater than 300 is a sign of very high to severe disease and heart attack risk.

You also may receive a percentile score, which indicates your amount of calcium compared to people of the same age and sex.

Does insurance cover the scan?

Unfortunately, insurances aren’t covering this test yet.

How much does it cost?

Our test cost $102.00 and you need a prescription.

Discussing results with your doctor

Your doctor will discuss the results of the heart scan with you. Depending on the outcome, one or more of the following strategies may be needed:

  • No change to current treatment plan
  • Different medication or dose of medication
  • Changes to your diet and exercise routine
  • New weight-loss goals for some
  • Additional tests
  • Follow-up appointments to monitor your health and treatment plan
  • Peace of mind
