Coronary CT calcium scan

A coronary CT calcium scan, also known as coronary artery calcium (CAC) test, is a computed tomography (CT) scan of the heart for the assessment of severity of coronary artery disease. Specifically, it looks for calcium deposits in atherosclerotic plaques in the coronary arteries that can narrow arteries and increase the risk of heart attack. These plaques are the cause of most heart attacks, and become calcified as they develop. These calcifications can be detected by CT imaging because of their opacity to x-rays. This severity can be presented as an Agatston score or coronary artery calcium (CAC) score. The CAC score is an independent marker of risk for cardiac events, cardiac mortality, and all-cause mortality. In addition, it provides additional prognostic information to other cardiovascular risk markers. Obstructions may be present even with an Agatston score of zero, especially in younger patients. A typical coronary CT calcium scan is done without the use of radiocontrast agent but it can also be performed using contrast-enhanced images as well, such as in coronary CT angiography. The exam is best performed with cardiac gating to eliminate motion but can also be estimated in the presence of motion.

• Coronary Artery Calcium Scoring | CardioSmart – American College of Cardiology

  A coronary calcium scan is a simple imaging test that helps estimate someone’s risk for heart disease, heart attack or stroke – even before other signs or symptoms develop. In some ways, CAC scoring is similar to a bone density test. Just as bone density helps predict the likelihood of a hip fracture, CAC helps estimate heart disease risk. ## Who Should Get a CAC Scan A CAC test detects early (subclinical) calcium and plaque buildup. It is best used: If there is uncertainty about one’s true risk of heart disease and related events and To help decide if starting a statin is needed CAC scoring is recommended for some: Men over age 40 Women over age 45 In particular, those who are at borderline or intermediate risk of having a heart attack or stroke in the next 10 years.

Please enter a valid search term # Coronary Artery Calcium (CAC) Scoring Coronary artery calcium (CAC) scoring – also called a coronary calcium scan – shows if calcium is present in the walls of the heart’s arteries and, if so, how much. Most calcium in your body is found in bones and teeth to help keep them strong and healthy. But calcium in the arteries that supply the heart can signal trouble for your heart health. Calcium in the coronary arteries often means plaque is building up. Plaque is a waxy substance that can harden and narrow or block the arteries (called atherosclerosis). This raises the chance (risk) of a heart attack or stroke. [...] A coronary calcium scan can help you and your care team better understand your future risk of having a heart attack, stroke or dying from one – even if you don’t have symptoms. It can also help decide if starting a statin, on top of healthy lifestyle changes, is needed to lower your risk. CAC scoring is not generally useful or helpful if you have: Low risk for heart disease (no risk factors) or High risk for heart disease or have heart disease already, or if you’ve already had a heart attack, stroke, stent or bypass surgery CAC scoring doesn’t identify if an artery is blocked. It also shouldn’t be used to assess whether treatment is working or not. ## What the Test Results Mean

• Is a Coronary Artery Calcium Scan Right for You? | News | Yale Medicine

  “A positive result should guide you, not define you,” says Andrew Levin, MD, a Yale Medicine cardiologist who researches how to better use CAC results in patient care. “It can help you assess how you can improve. I spend a lot of time talking to patients who have taken this test about their lifestyle. We talk about statins. These are things that can help you take control of your health,” he says. ## What is a coronary artery calcium scan—and what does it show? A CAC scan is a quick, noninvasive CT scan of the chest that measures calcified plaque in the coronary arteries. These arteries supply blood to the heart. Plaque buildup—known as coronary artery disease—is a leading cause of heart attack. The test does not require contrast dye and typically takes about 15 minutes. [...] # Is a Coronary Artery Calcium Scan Right for You? March 31, 2026 Scan of Heart on Computer Screen If you have high cholesterol and are unsure whether you need a statin, a coronary artery calcium (CAC) scan may help clarify your risk. The test measures calcified plaque in the coronary arteries—the arteries that supply blood to the heart. Plaque buildup, known as coronary artery disease, is a leading cause of heart attack. For some people, the CAC scan helps answer a practical question: Do I really need cholesterol-lowering medication? In certain cases, it can tip the balance toward starting a statin—or support waiting and focusing on lifestyle changes instead. [...] You may have heard of the CAC scan by a different name: It’s also known as cardiac calcium scoring because it measures—or scores—plaque in the arteries. It’s an increasingly popular type of computed tomography (CT) scan that tripled in usage between 2006 and 2017, according to one study, and interest in it has continued to explode, says Antonio Giaimo, MD, a Yale Medicine cardiologist. But whether it’s right for you—and how to interpret the results—requires an individualized discussion.

• Coronary Calcium Score by Age | HLHV Conroe, TX

  For a foundational explainer on what calcified plaque is and why it matters, see our companion post How Serious Are Coronary Artery Calcifications?. This post focuses specifically on how to interpret the number you got back. ## What a CAC scan actually measures A coronary artery calcium (CAC) scan is a low-radiation, non-contrast CT of the chest. It quantifies calcified plaque in the coronary arteries using a standardized scoring method called the Agatston score. The scan does not require any dye, takes about 10 minutes, and the result is a single number. 5,000+ Combined monthly US searches for “calcium score by age” and related variants. The interpretation question is the most common one we hear after the scan result comes back. [...] For most patients in their forties with strong family history of premature CAD, a CAC scan is a reasonable test. It can clarify whether early atherosclerosis is already present and change the medication conversation. We typically discuss it at the first preventive cardiology visit and order it if it would actually change the plan. ### Does insurance cover the CAC scan? Coverage varies. Some insurers cover CAC for intermediate-risk patients with family history concerns. Many do not cover routine screening CAC scans. In Texas, the cash-pay price for a CAC scan is often affordable (typically in the range of $100 to $400 depending on imaging center). Our office can verify coverage before scheduling. ### How often should the scan be repeated? [...] For HLHV patients with family history specifically, see our Family History of Heart Disease screening guide. ## How CAC complements your cholesterol panel A common patient question is, "My cholesterol is normal. Why do I need this scan?" The answer is that a CAC scan measures something different from a lipid panel. A lipid panel measures risk factors for atherosclerosis. A CAC scan measures whether atherosclerosis has actually developed. “A score of 100 at 70 is roughly what we expect. A score of 100 at 40 is a wake-up call.”

• Cardiac Calcium Scoring (Heart Scan)

  Image 2: Medical scan of coronary calcium The coronary arteries are the vessels that supply oxygen-rich blood to the heart. Plaque — made of fat, calcium and other substances — can build up and narrow or close the arteries. To detect this build-up, your physician may order cardiac calcium scoring — a test that is also known as coronary artery calcium (CAC) scoring, a heart scan or calcium score. The procedure is performed at the University Imaging Center at UMMC. To make an appointment call 410-328-3225. This non-invasive CT scan (computed tomography) of the heart calculates your risk of developing coronary artery disease (CAD) by measuring the amount of calcified plaque in the coronary arteries. [...] Plaque or calcium build-up in the coronary arteries causes heart disease or can lead to a heart attack. The coronary calcium scan is a better predictor of coronary events than cholesterol screening or other risk factor assessments. ## About Your CAC Score A calcium score (sometimes called an Agatston score) is calculated based on the amount of plaque observed in the CT scan. It may be converted to a percentile rank based on your age and gender. The results from your cardiac scoring will be sent to your doctor. Your likelihood of having heart disease or a heart attack correlates with your calcium scoring. The lower your calcium score and percentile rank, the less likely you are to have a cardiac event compared to other men or women your age. ## Calcium Score Results
