Seeing Plaque Directly
A coronary artery calcium (CAC) scan is a quick, low-radiation CT scan that measures calcified plaque in the heart arteries, producing a score that reflects the burden of atherosclerosis. Unlike risk calculators that estimate probability from factors like age and cholesterol, a calcium score reveals what is actually happening in an individual arteries, which can dramatically refine risk assessment and clarify treatment decisions for people in an intermediate risk category.
When It Helps
Calcium scoring is most useful for people at intermediate cardiovascular risk who are uncertain about whether to start preventive medication like statins. A score of zero indicates very low near-term risk and may support a more conservative approach, while a high score reveals significant disease that warrants aggressive prevention even if standard risk factors looked reassuring. It essentially resolves ambiguity by showing the actual state of the arteries.
Interpreting and Acting
A calcium score is a snapshot of accumulated plaque, and it complements rather than replaces other risk assessment. It does not detect soft, non-calcified plaque, so a zero score is not an absolute guarantee. Used appropriately in the right patients, it is a powerful tool for personalizing prevention and motivating lifestyle and treatment decisions. Discussion with a clinician guides its use.
