Overview
May refine mortality risk assessment beyond age; extends CAC data to extremes but leaves practice change open.
Key Points
- This research evaluates the efficacy of coronary artery calcium (CAC) in predicting mortality for young adults under 45 years and elderly adults over 75 years.
- Assessed mortality risk (MR) in elderly persons with no CAC and younger persons with high CAC.
- Compared mortality prediction using CAC in both age groups.
- Elderly individuals with no CAC demonstrate a lower mortality risk compared to younger individuals with high CAC levels.

CAC scoring is a valuable predictor of mortality across age extremes, demonstrating that biological age (as measured by CAC) can trump chronological age in risk assessment.
