Coronary Calcium Score Age-Equivalent Interpreter

Translate a coronary artery calcium score into arterial age context that patients and clinicians can act on. Combine chronological age, Agatston score, sex, and statin therapy to see your arterial-age equivalent, percentile versus peers, and suggested talking points for follow-up care.

Chronological age in years at the time of the coronary calcium CT scan.
Total Agatston value reported on your coronary calcium CT interpretation.
Use 1 for male and 0 for female so results line up with sex-specific percentile curves.
Enter 1 if you are currently prescribed statin therapy and 0 if you are not.

The output is educational and not a diagnosis. Always consult a healthcare professional for personalised cardiovascular care.

Examples

  • Example 1 — 52-year-old male, Agatston score 180, currently on statin therapy ⇒ Arterial age estimate: 68.0 years | Risk tier: Moderate plaque burden | Peer percentile: 89th percentile | Suggested follow-up: Prioritise LDL reduction, blood pressure control, and consider coronary CT angiography per clinician guidance.
  • Example 2 — 60-year-old female, Agatston score 35, not on statin therapy ⇒ Arterial age estimate: 64.8 years | Risk tier: Mild plaque burden | Peer percentile: 71st percentile | Suggested follow-up: Intensify risk-factor control and discuss repeat scan in 3 to 5 years.

FAQ

Is this a substitute for medical advice?

No. Use the interpretation as a discussion aid with your clinician. Treatment decisions require a full review of history, labs, and imaging.

How often should I rescan?

Low or zero scores typically repeat every 5 years, while moderate-to-high results warrant re-evaluation within 3 years or sooner if symptoms emerge.

What if I do not know my exact Agatston score?

Request the numeric score from your imaging report. Percentile tables or category descriptions are not precise enough for this calculator.

Does aspirin therapy change the result?

This tool does not adjust for aspirin. Discuss aspirin use separately with your cardiology team based on bleeding risk and plaque burden.

How should I interpret arterial age?

Arterial age compares your coronary plaque burden with the average person of that arterial age. A higher arterial age signals the need for aggressive lifestyle, lipid, and blood-pressure interventions.

Can I use this after a new statin prescription?

Yes. Re-run the calculator with statin therapy marked as 1 to see how ongoing treatment can modestly reduce arterial-age estimates over time.

Additional Information

  • Arterial age is capped at 95 years and never drops below chronological age to avoid understating inherent risk.
  • Percentile approximation uses sex-specific baseline curves adjusted for age to mirror published MESA references.
  • Risk tiers follow standard 0, 1–99, 100–299, and ≥300 Agatston brackets for preventive cardiology consults.
  • Statin therapy reduces the arterial-age estimate slightly to reflect plaque-stabilisation effects.
  • Outputs display with one decimal place and en-US formatting so they are easy to copy into clinical notes.
