A coronary calcium scan uses computerized tomography (CT) imaging to take pictures of your heart's arteries. It can detect calcium deposits in the coronary arteries. Calcium deposits can narrow the arteries and increase the risk of a heart attack.
Uncover your heart attack risk with a quick coronary calcium scan. This CT scan detects plaque, giving insight into your heart health and potential risks.
Your calcium score gives your health care team an idea of how much plaque is in your heart arteries and may help predict your risk of a future heart attack. Your CAC score can help you determine your risk of cardiovascular disease. It’s particularly helpful if you’re at “intermediate” risk.
A calcium score test is a CT (computed tomography) scan that looks at how much calcium is in your coronary arteries. Calcium in your heart’s arteries can tell you if you have a buildup of a waxy, fatty substance (plaque) that can narrow or block them.
Get an overview of coronary calcium scan, including what a CT coronary calcium scan indicates, how doctors use the coronary calcium scan score range, how the scan is done, and what it tells doctors about atherosclerosis and coronary artery disease.
A score ranging from 100 to 300 indicates a moderate amount of calcium and suggests a relatively high risk of heart attack or other heart disease over 3 to 5 years. Finally, a score above 300 may indicate more extensive heart disease and a higher risk of heart attack.
A coronary calcium scan is a non-invasive test that measures the amount of calcium in the arteries that supply blood to the heart, called coronary arteries. This painless scan is done using computed tomography (CT), which uses X-rays and computers to create detailed images of the heart.
