The Claim
Coronary artery calcification, as quantified by noninvasive computed tomography, is an independent predictor of future cardiovascular events, with a CAC score above 400 indicating high cardiovascular risk and a CAC score of zero conferring the strongest negative predictive value for coronary heart disease over a 10-year period.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
A calcium buildup in the heart arteries, measured by a CT scan, predicts the likelihood of future heart problems: higher scores mean higher risk, and a score of zero strongly indicates no heart disease within 10 years.
See the scientific wording
Coronary artery calcification (CAC), quantified by noninvasive computed tomography, is a strong independent predictor of future cardiovascular events, with a CAC score above 400 indicating high cardiovascular risk and a score of zero conferring the strongest negative predictive value for coronary heart disease over 10 years.
Cells in the artery wall change into bone-like cells, release tiny sacs that trap calcium and phosphate, and form hard mineral deposits inside the artery walls, which show up as calcification on a CT scan.

A CT scan that measures calcium in the heart arteries can tell if someone is likely to have a heart attack in the next 10 years: no calcium means very low risk, and a lot of calcium (over 400) means high risk. The study confirms this is true.
