A calcium test for the heart, also known as a coronary calcium scan, is a specialized imaging procedure used to assess the presence and extent of calcium deposits in the heart's arteries.
Understanding the Coronary Calcium Scan
What It Is
- A coronary calcium scan is a specific type of computerized tomography (CT) scan that focuses on the heart.
- The scan's primary purpose is to identify calcium buildup within the coronary arteries.
- According to the provided reference, it is a special computerized tomography (CT) scan of the heart.
Why It Matters
- Calcium deposits in the arteries can lead to narrowing and reduced blood flow, which increases the risk of coronary artery disease.
- This scan can detect coronary artery disease, or blockages in the arteries that supply the heart, even before symptoms appear.
- The presence of calcium in the arteries is often a sign of atherosclerosis, a condition where plaque builds up in the artery walls.
- This buildup can lead to heart attacks, strokes, or other cardiovascular problems.
How It Works
- During the scan, you will lie on a table while a CT scanner takes detailed images of your heart.
- The scan is non-invasive and requires no injections of contrast dye.
- The images show the degree of calcium accumulation in your arteries, providing a calcium score.
What the Score Means
- A higher calcium score indicates a larger amount of calcified plaque.
- This means you have an increased risk of developing heart disease.
- A lower calcium score generally signifies a lower risk.
- The results help healthcare providers assess your cardiovascular health and make recommendations about lifestyle changes or medical treatments.
Key Takeaways
- The scan is an effective method for identifying calcium buildup.
- It helps detect potential problems early on.
- It aids in preventative care and effective management of coronary artery disease.
- The scan, according to the reference, may show coronary artery disease before you have symptoms.
