What is CT Calcium Score? A painless heart scan that helps assess risk before symptoms appear
Coronary artery disease is often a “silent threat” that shows no warning signs until it’s too late. The CT Calcium Score test is a medical innovation that helps assess risk in advance without causing you any pain at all.
What is CT Calcium Score? What can it detect?
CT Calcium Score or coronary artery calcium scoring is a test using a computed tomography (Multi-Detector CT) scanner to image the accumulation of calcium or “calcification” on the walls of the coronary arteries.
This calcification indicates atherosclerosis, which, if it accumulates progressively, can cause artery narrowing and lead to myocardial ischemia or acute heart attack.
Why test for calcium in the coronary arteries?
Calcium testing is not just a general health check but a “forecast” of your heart’s future.
- Risk screening indicates the likelihood of developing ischemic heart disease in the future
- Early detection identifies abnormalities even when the body appears healthy and there is no chest pain
- Treatment planning helps doctors make more accurate decisions regarding medication (such as cholesterol-lowering drugs) or lifestyle adjustments
Who should get a CT Calcium Score test?
The group recommended for screening usually includes those with moderate risk as follows:
- Individuals aged 45 and above (both men and women)
- Those with a family history of coronary artery disease
- People with diabetes, high blood pressure, or high blood cholesterol
- Regular smokers
- Those who are obese or lack physical exercise
What Calcium Score is considered dangerous?
After the test, doctors interpret the results as a score (Agatston Score) as follows:
| Score | Risk Level | Meaning |
|---|---|---|
| 0 | Very low | No calcification found, low chance of coronary artery disease |
| 1 – 100 | Low – Moderate | Minimal calcification, early stage of disease |
| 101 – 300 | High | Moderate calcification, risk of coronary artery disease |
| More than 300 | Very high | Dense calcification, high risk of acute heart attack |
How to prepare? Painless heart scan
The advantage of this test is “painless, no contrast injection, no hospitalization required” with minimal preparation.
- Preparation: Avoid caffeine-containing drinks (tea, coffee) at least 4-6 hours before the test to keep the heart rate normal
- Test procedure: You simply lie on the CT Scan machine and hold your breath briefly as instructed by the staff. The test takes only 10-15 minutes to complete
Knowing your risk score while you “still have no symptoms” is the key to preventing heart disease. If you are in a risk group, consulting a doctor for a CT Calcium Score test may be the crucial key to saving your life in the long term.
Note: Even if the Score is 0, maintaining health through diet control and exercise remains essential and should not be neglected.
