The coronary artery calcium score (CAC-score) using imaging is a cardiovascular screening tool that can be used in adults with no known cardiovascular disease and no symptoms suggestive of a cardiovascular pathology. It involves calculating the amount of calcification in the coronary arteries on a low-dose, non-injected chest CT-scan. A positive score above 0 is associated with more cardiovascular events. The CAC-score is currently selectively recommended for certain adults at intermediate cardiovascular risk, when the introduction of lipid-lowering treatment or the intensification of preventive measures remain uncertain.
