Imaging
Coronary Artery Calcium (CAC) Score
Low-dose CT scan quantifying calcified plaque in coronary arteries — a powerful predictor of future cardiac events.
Optimal Range
0 (ideal) · 1-100 (mild) · >400 (severe)
Why It Matters
A CAC score of 0 is highly reassuring and reclassifies cardiac risk downward regardless of other risk factors. A score above 100 warrants aggressive lipid management. It is one of the most cost-effective cardiac screening tests available.
