Calcium Score Screening

A coronary calcium scan is a special computerized tomography (CT) scan of the heart. It looks for calcium deposits in the heart arteries. A buildup of calcium can narrow the arteries and reduce blood flow to the heart. A coronary calcium scan may show coronary artery disease before you have symptoms.

​

Coronary calcium scan results can help determine the risk of heart attacks or strokes. Results from the scan may be used to plan or change treatment for coronary artery disease.

 

Other names for this test are:

  • Coronary artery calcium (CAC) test.

  • Coronary calcium CT scan.

  • Heart CT calcium scan.

​

​

  • A coronary calcium scan is done to check for calcium in the arteries that supply the heart. It can help diagnose early coronary artery disease.

    ​

    Coronary artery disease is a common heart condition. A buildup of calcium, fats and other substances in the heart arteries are often the cause. This buildup is called plaque. Plaque collects slowly over time, long before there are any symptoms of coronary artery disease.

    A coronary calcium scan uses a series of X-rays to take pictures that can see if there's plaque that contains calcium.

     

    This test might be done if:

    • You have a strong family history of early coronary artery disease.

    • Your risk for heart attacks is intermediate, not low or high.

    • Your level of risk of heart attacks is uncertain.

    A coronary calcium scan may help:

    • Understand your risk of heart disease.

    • Plan treatment if you have a low to moderate risk of heart disease or if your heart disease risk isn't clear.

     

    A coronary calcium scan is not recommended as a general screening test for those known to be at high risk for heart attacks. It also isn't suggested if you have had a heart attack, a heart stent or coronary bypass surgery — because other tests or procedures that are done for those events show the heart arteries. Ask your health care team if a coronary calcium scan is right for you.

  • A coronary calcium scan utilizes X-rays, which involve radiation that is generally considered safe.

    ​

    Some medical centers promote these scans as a convenient method to assess heart attack risk, often not requiring a referral. However, they might not be covered by insurance. Less expensive alternatives, such as blood tests and blood pressure checks, can also provide valuable insights into your heart attack risk. It is advisable to consult your doctor to determine the most suitable heart tests for you.

  • During the procedure:

    • Before a coronary calcium scan begins, sticky patches called electrodes are placed on your chest and sometimes your arms or legs. Wires connect the patches to a machine that checks your heartbeat.

    • The scan is done using a computerized tomography (CT) scanner. You lie on your back on a movable table. The table slides into a large machine shaped like a tube. Your head is outside the scanner the whole time. The exam room will likely be cool.

    • You may be given medicine to slow your heartbeat. This helps create clearer images. If you are nervous or anxious, you may get medicine to relax you.

    • You need to stay still while the pictures are taken. You may be asked to hold your breath for a few seconds. The health care professional doing the test can see and talk to you the entire time. The test takes about 10 to 15 minutes.


    After the procedure:
    You usually can drive yourself home and continue your daily activities after the test unless your doctor tells you not to do so.

  • Your health care team gives you your coronary calcium scan results. The result of a coronary calcium scan shouldn't be used as a single sign of your overall health and risk of heart disease. The information from the scan should be reviewed with other health information.


    After a coronary calcium scan you may need one or more of the following plans:

    • No change to your current treatment.

    • A different medicine or dose of medicine.

    • Changes to your diet and exercise routine.

    • New weight-loss goals.

    • More tests.

    • Follow-up appointments to check your health and how well treatment is working.


    If a coronary calcium scan shows calcium in the heart arteries, the test is not usually done again.

Benefits of a Calcium Score Screening

  • Non-Invasive screening is used to check for cholesterol buildup & hardened, or calcified, plaque on the walls of the arteries in the heart.

  • Detects coronary artery disease before any symptoms occur.

  • No IV contrast.

  • Only tales a few minutes!

  • Most accurate non-invasive diagnostic test for coronary arteries

Benefits of a Coronary CTA

  • Provides high-definition 3-D images of the arteries feeding the heart and blockages at the earliest stages

Who Should Consider a Coronary CTA?

  • A person with chest pain, shortness of breath, or other symptoms of coronary artery disease

  • Unclear or inconclusive stress test results

  • Strong family history of early heart disease

  • Hypertension, Diabetes, Cholesterol Abnormality, or a High Coronary Calcium Score

Who Should Consider Calcium Score Screening?

  • Men Over 40 & Women Over 45 with one of the following risk factors:

  • Diabetes,

  • Current Smoker,

  • Obese,

  • Family History of Heart Diseases,

  • Abnormal Cholesterol Levels,

  • Abnormal Blood Pressure
