Coronary calcium score is an independent predictor of risk of significant coronary artery disease. It may refine overall risk of coronary artery disease estimated with conventional risk factors. It is based on CT examination and calculation of the Agatston score from the images.
Calcium score | Risk of significant CAD |
---|---|
0 | very low |
≤10 | low |
≤100 | moderate |
≤400 | moderately high |
>400 | high |
Youssef et al. used a different description for calcium score intervals:
Calcium score | Risk | RR |
---|---|---|
<100 | average risk | 1.9 |
<400 | moderate risk | 4.3 |
<1000 | high risk | 7.2 |
≥1000 | very high risk | 10.8 |
