Calcium Score Scan: A Non-Invasive Test for Heart Disease

Feb 28, 2023

HEALTH,INSIGHTS

A calcium score scan, also known as a coronary calcium scan, is a non-invasive diagnostic test that uses computed tomography (CT) imaging to measure the amount of calcium buildup in the coronary arteries.

Calcium Score Scan: A Non-Invasive Test for Heart Disease

A calcium score scan is a non-invasive test that uses low-dose X-rays to measure the amount of calcium in the coronary arteries. Calcium deposits are a sign of atherosclerosis, a buildup of plaque in the arteries that can lead to heart disease.

The calcium score scan is a relatively new test, but it has been shown to be a good predictor of coronary artery disease. A high calcium score indicates a higher risk of heart attack and other cardiovascular events.

Benefits of Calcium Score Scans

Non-invasive and painless
Relatively quick and easy to perform
Can be used to detect coronary artery disease in people at increased risk
Can be used to monitor the progression of coronary artery disease over time

Risks of Calcium Score Scans

Can give false positives
Can miss some cases of coronary artery disease
Exposes the patient to low-dose radiation

Who Should Get a Calcium Score Scan?

People who are at increased risk for coronary artery disease, such as those with high blood pressure, high cholesterol, or a family history of heart disease
People who have already had a heart attack or other cardiovascular event
People who are considering undergoing other tests for coronary artery disease, such as an electrocardiogram (EKG) or coronary angiography

How Is a Calcium Score Scan Performed?

The patient lies on a table and is exposed to low-dose X-rays for about 10 minutes. The X-rays are used to create a three-dimensional image of the heart and coronary arteries. The computer then calculates the amount of calcium in the arteries.

What Do the Results of a Calcium Score Scan Mean?

The results of the calcium score scan are given as a number called an Agatston score. The Agatston score ranges from 0 to 400. A score of 0 means that there is no calcium in the arteries. A score of 1 to 100 indicates a low risk of coronary artery disease. A score of 101 to 400 indicates a moderate to high risk of coronary artery disease.

Calcium Score Scans and Treatment

A high calcium score does not necessarily mean that you will have a heart attack or other cardiovascular event. However, it does indicate that you are at an increased risk for these events. If you have a high calcium score, your doctor may recommend lifestyle changes, such as losing weight, eating a healthy diet, and exercising regularly. Your doctor may also recommend medication to lower your blood pressure, cholesterol, or blood sugar.

Calcium Score Scans and Early Detection

Calcium score scans are a valuable tool for early detection of coronary artery disease. Early detection and treatment can help to reduce the risk of heart attack and other cardiovascular events.

If you have any questions about calcium score scans, please talk to your doctor.
