Diagnostic performance of CT coronary calcium scoring

What is the diagnostic performance of CT coronary calcium scoring?

Coronary calcium scoring allows for detection and quantification of subclinical coronary atherosclerosis. It has been shown to identify at-risk patients with a higher predictive accuracy than conventional risk factor assessment. Moreover, the Multi-Ethnic Study of Atherosclerosis (MESA) trial of 6809 patients demonstrated that coronary calcium score was the most accurate tool for predicting long-term cardiac events. Compared to patients with no coronary calcium, hard event rates in patients with scores from 101 to 300 were increased 7.73-fold, and 9.67-fold among those with a score above 300. Three other large trials have confirmed the benefits of imaging subclinical coronary atherosclerosis for improved risk prediction, including in elderly patients.
