The role of coronary artery calcification (CAC) detection in individuals undergoing medical therapy is controversial. These patients frequently exhibit an artificially low clinical suspicion for obstructive heart disease. Whether detection of CAC adds value to their assessment is unknown. ⋯ The presence of a CAC score greater than 400 is associated with ischemia in a population receiving good medical therapy. The detection of significant CAC in these individuals warrants additional evaluation for ischemia.
