What the scan measures
A non contrast CT counts calcified plaque in the coronary arteries and compresses it into the Agatston score. Calcium marks healed plaque, so the score is a fossil record of atherosclerosis rather than a snapshot of soft blockages.
Understanding your result
- Zero means no detectable plaque and very low near term risk
- 1 to 99 is mild disease
- 100 to 399 is moderate and usually triggers statin therapy
- 400 or more approaches the risk of someone who already had an event
The power of zero
In intermediate risk adults a zero score reclassifies most people downward and can safely defer statins for years, which is why guidelines endorse the scan for decision uncertainty.
Limits
The score does not see soft plaque, so symptoms always outrank the number. Scores also rise with age even in healthy arteries.
