A Calcium Scoring CT scan is a fast, non-invasive procedure that assesses the level of calcium deposits in your coronary arteries. This calcium accumulation, referred to as coronary artery calcification, is a significant marker for coronary artery disease (CAD). The test is especially useful for those with moderate risk factors for CAD, such as a family history of heart issues, elevated cholesterol, or high blood pressure, even if they haven’t experienced any symptoms yet. Its importance lies in providing a numerical score that helps evaluate your risk of a heart attack or other cardiac events, enabling proactive management and lifestyle adjustments.
Procedure Overview
During a Calcium Scoring CT scan, you’ll lie on a table that slides into a CT scanner. Electrodes will be placed on your chest to monitor your heart’s rhythm. The scanner takes rapid, low-dose X-ray images of your heart, capturing detailed cross-sectional views. A computer then analyses these images to calculate your calcium score, which reflects the amount of calcified plaque in your coronary arteries. The entire procedure typically takes only about 20-25 minutes. At Heartmatters, we utilise advanced multi-detector CT scanners that minimise radiation exposure while providing accurate and reliable results.
Benefits & Importance
The Calcium Scoring CT scan offers a significant advantage over traditional risk assessments that rely solely on factors like age, cholesterol, and blood pressure. It provides a direct measure of coronary artery calcification, offering a more precise estimate of your risk. This allows for earlier detection of CAD, enabling timely interventions and lifestyle modifications to prevent future cardiac events. By quantifying your risk, it helps you and your doctor make informed decisions about your heart health.
Preparation & Requirements
The Calcium Scoring CT scan requires minimal preparation. You don’t need to fast or stop taking any medications. It’s important to wear comfortable clothing and remove any metal objects from your chest area. During the scan, you’ll be asked to hold your breath for short periods. After the scan, you can resume your normal activities immediately.
Risks & Considerations
The Calcium Scoring CT scan involves a small amount of radiation exposure, but the benefits of early detection generally outweigh the risks. The scan is not recommended for pregnant women. Individuals with very rapid or irregular heartbeats might have difficulty obtaining accurate results. It’s crucial to discuss your medical history and any concerns with your doctor to ensure the procedure is appropriate for you. A zero calcium score does not mean there is no risk, just that there is no calcified plaque at the time of the scan.
Understanding your risk of heart disease is essential for maintaining a healthy heart. A Calcium Scoring CT scan at Heartmatters can provide valuable insights into your coronary artery health, allowing for proactive management and lifestyle changes. If you have risk factors for heart disease or are concerned about your heart health, don’t wait.
