CT Calcium Score, also known as a coronary calcium scan, is a specialised computed tomography (CT) scan measures the amount of calcified plaque that has built up in the coronary arteries. Calcified plaque is an indicator of atherosclerosis or coronary artery disease (CAD), which can lead to cardiovascular diseases such as heart attack and stroke. This non-invasive test helps assess the risk of CAD by providing a calcium score that reflects the extent of plaque buildup.

In 2022, cardiovascular diseases accounted for 31.4% of all deaths in Singapore. Given this significant impact, regular screening through tests like the CT calcium score test allows for early detection, helping to manage and mitigate the risks associated with heart disease and improve health outcomes.

A CT calcium score test is generally conducted as follows:

• Preparation: Avoid caffeine and exercise a few hours before the test. Just before the procedure, you will need to change into a special gown and remove items such as jewellery and spectacles.
• During the Test: You will lie on a special table that slides into the CT scanner. Small sticky electrode patches will be placed on your chest to monitor your heart's electrical activity. The CT scanner will take multiple high-speed images synchronised with your heartbeat. You may be asked to hold your breath for short intervals during the scan to get clear images.
• Post-Test: After the scan, the images are analysed to determine the presence and extent of calcified plaque in the coronary arteries.

The results of the CT Calcium Score test are given as a numerical score that indicates the amount of calcium in your coronary arteries. The higher the score, the higher the risk of cardiovascular diseases. Based on the results, your doctor may recommend appropriate preventive measures, such as lifestyle changes, medications, or further testing.

CT calcium score test is one of various tests that provide insights into different aspects of cardiovascular health. Some examples include:

• Electrocardiogram (ECG): Measures the heart’s electrical activity to detect arrhythmias, heart attacks, and other cardiac conditions.
• CT Coronary Angiography (CTCA): Similarly uses computed tomography (CT) to scan the heart’s blood vessels, assessing for any blockages. A contrast dye is injected into a vein to enhance the images and allow for detailed evaluation of the arteries.
• Carotid Intima-Media Thickness (CIMT) Test: Uses ultrasound to measure the thickness of the inner two layers (intima and media) of the carotid arteries to assess for atherosclerosis.
• Stress Tests: Assesses heart function under physical stress, useful for detecting significant blockages and gauging overall cardiovascular fitness.

CT calcium score is a useful, non-invasive tool in the early detection and risk assessment of coronary artery disease. It provides a clear and quantifiable measure of calcified plaque in the coronary arteries, offering insights into heart health and guiding preventive strategies for individuals at risk of heart disease. If you are unsure which cardiovascular tests are most suitable for you, schedule an appointment to consult a doctor and discuss your options.
