What are the diagnostic sensitivity and specificity of CAC score to predict obstructive CAD on invasive angiography?
The estimated diagnostic sensitivity for the CAC score to predict obstructive CAD on invasive angiography was 85%, with a specificity of 75%. In a recent meta-analysis of 18 studies, the presence of nonzero CAC score had a pooled sensitivity of 98% and a specificity of 40%, respectively, for the detection of significant CAD on invasive coronary angiography.
