What Is a Calcium Score? A Simple Guide to This Heart Test
Have you ever felt perfectly fine but wondered quietly — is my heart truly okay? That is exactly the question a calcium score test can help answer.
What Is a Calcium Score?
A calcium score — also called a Coronary Artery Calcium (CAC) score — is a special, non-invasive CT scan. It looks inside your heart arteries to check for calcium deposits.
Why does calcium matter? When plaque slowly builds up inside the arteries over the years, calcium gets deposited along with it. This plaque can narrow the arteries and raise your risk of a heart attack — often long before you feel any symptoms.
The calcium score test picks up this hidden buildup early, giving you and your doctor a clear picture of what is happening inside.
What Do the Numbers Mean?
The result is a simple number:
- Score of 0 — Very low risk. Calcium deposits are not detected in the arteries at this time.
- Low score — Some plaque may be present. Lifestyle changes are usually recommended.
- Higher score — More significant plaque buildup. Your cardiologist will discuss medicines, lifestyle changes, and a closer follow-up plan to lower your risk of a future heart attack.
The higher the score, the greater the attention needed — but the good news is that finding out early gives you time to act.
Who Should Consider This Test?
A calcium score test is generally useful for people at intermediate risk of heart disease — for example, those with a family history of heart attacks, diabetes, high blood pressure, high cholesterol, or smoking history, especially when a routine check-up does not give a clear picture of their risk level. Your cardiologist is the right person to decide if this test suits you.
Why Is Early Detection Important?
Heart disease often develops silently over many years. By the time chest pain or breathlessness appears, significant damage may already have occurred. A calcium score test helps catch the problem at an early, manageable stage — when lifestyle changes and treatment can make a real difference.
The scan itself is quick and comfortable, with no injections or dye required in most cases.
