Computed Tomography for Coronary Artery Calcification Scoring: Mammogram for the Heart

Another entry in the “calcium scan as a mammogram for the heart” genre, this review argues the case for CAC scoring in primary prevention with particular clarity on what to do with the result.

The core claims are by now well established: the calcium score predicts cardiovascular events better than traditional risk factors alone, and it sorts in both directions. A score of zero marks a genuinely low-risk person who may reasonably skip pharmacological treatment, while a high score supports aggressive prevention — turning a population-average risk estimate into a personalized decision.

The practical takeaway is to use CAC to refine treatment decisions in asymptomatic people, especially to de-escalate in those with a zero score and intensify in those with a high one. The resistance is gentle — it nudges clinicians off reliance on traditional risk scores alone.

We rate the evidence moderate: a 60-reference synthesis, single-center authorship (a mild bias caveat) but no direct conflicts, and no new data. Its clinical significance is solid — CAC genuinely improves risk stratification for a large primary-prevention population — though, like its companion reviews, it stops short of the outcome-trial evidence that would settle the universal-screening question.
