Calcium Score / CT heart scan

Are you at risk?

OVERVIEW

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.

A heart scan (coronary calcium scan) provides pictures of your heart’s arteries. Doctors may use this test to look for calcium deposits in the coronary arteries that can narrow your arteries and increase your heart attack risk. The image on the left shows where the heart is located in the body (A), and the middle image shows the area of the coronary calcium scan image (B).

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.

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

Risks

Heart scans use X-ray technology, which requires radiation exposure. The amount of exposure is generally considered safe — about the same amount of radiation you’re naturally exposed to in a year.

How you prepare

When scheduling your heart scan appointment, ask these questions:

  • Are there any special instructions?
  • How early should I arrive?
  • What paperwork or identification will I need?

Food and medications

You may be asked to avoid caffeine and smoking for four hours before the test.

Clothing and personal items

When you arrive for the procedure, 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 technician 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 may be given medication either by pill or injection that slows your heart. This helps ensure clear images. If you are nervous or anxious, you may be given medication to help you remain calm.

You’ll be asked to lie still and hold your breath for a few seconds while the pictures are taken. The technician 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 should 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.

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
  • Additional tests
  • Follow-up appointments to monitor your health and treatment plan

Disclaimer

The We Have Heart Program is designed to bring awareness to your potential heart risk. Those who score over 10% are encouraged to take steps to improve heart health and seek the advice of a Healthcare Cardiac Provider. It is always recommended that if you feel you are having a heart attack you should call 911 or go to your local ER. If you have a pre-existing known heart condition this program is not for you, you should consult with your Cardiologist directly. (Click here to meet our Cardiology team). The data you provide is based on your personal patient data input into the Framingham Heart Study Risk Calculator. Middletown Medical will not see or retain the results of your score. Submittals requesting a free CT Scan through this program are not monitored the same as a regular request to see a provider for medical attention. Notifications of submittals sent to Middletown Medical may be evaluated daily, and there is no guarantee that you will be selected. However, if your risk score is above 10% it is encouraged that you reach out to your cardiologist directly and not solely through this program. Middletown Medical reserves the right to cancel this program at any time. Middletown Medical reserves the right to suspend the issuance of a CT heart scan to any person who based on medical reasons should not have a CT heart Scan. In the event that your CT Heart Scan shows a risk to your health Middletown medical will refer you to a Cardiologist. Visits beyond that of the initial visit are not covered by this program and will result in a cost to the patient or their insurance provider. Only four free CT Scans will be awarded for each day of the month of March. It may take 48 hours for the staff of Middletown Medical to reply to your request for this program. If you are in need of immediate assistance due to a heart-related concern we advise you to go to your local ER.
