A coronary artery calcium score, often called a CAC score, estimates the amount of calcified plaque in the coronary arteries using a specialized CT scan. It can help refine cardiovascular risk in selected people, but there is no single “normal” score that applies to every 60-year-old.
How CAC Scores Are Interpreted
A score of zero means no detectable calcified coronary plaque on the scan. Higher scores indicate more calcified plaque. Common categories include 0, 1–99, 100–399 and 400 or higher, but interpretation should consider age, sex, risk factors and the clinical context.
Why Age Matters
Coronary calcium tends to become more common with age. A score that may be more concerning in a younger adult can have a different meaning in an older adult. Clinicians may also consider a percentile compared with people of similar age and sex.
What Can Affect Cardiovascular Risk?
- Blood pressure
- Cholesterol levels
- Diabetes
- Smoking history
- Family history of premature cardiovascular disease
- Age and other established risk factors
Does a Calcium Score Diagnose a Heart Attack?
No. CAC scanning is primarily a risk-assessment tool. It does not directly show every type of plaque and is not the same as a test used to diagnose an acute heart attack. New chest pressure, shortness of breath, fainting or other concerning symptoms require prompt medical evaluation.
What Happens After a High Score?
A higher score may prompt a clinician to review cholesterol, blood pressure, diabetes risk, smoking, diet, exercise and other preventive strategies. Treatment decisions should be individualized rather than based on the score alone.
Final Thoughts
A calcium score provides one piece of the cardiovascular-risk picture. At age 60, the meaning of a result depends on the person and their overall risk profile. Discuss the result with a qualified clinician who can put it into context.
