It means imaging does not show a buildup of calcified plaque in the heart’s blood vessels. Coronary artery calcium (CAC) scores show the calcium level in the arteries. CAC levels can help ...

The Cardiac CT calcium score (CAC score) is a noninvasive test used to detect calcified plaques in coronary arteries and predict heart disease risk. Scores range from 0 (no risk) to above 300 ...
