©2013 UpToDate ® Print Email Diagnostic yield of calcium screening in symptomatic men and women In a study of 1764 symptomatic patients with suspected coronary heart disease who underwent electron beam computed tomography (EBCT) and coronary angiography, the calcium score on EBCT correlates with the presence or absence of a significant stenosis on angiography. The higher scores (A for men and C for women) define the calcium score thresholds (CSTs) for the 90 percent of patients with significant stenoses, while the lower scores (B for men and D for women) define the CSTs for the 95 percent of patients without significant stenoses. For example, a man at the age of 50 years is probably free of coronary stenosis if his score is <56. At score values >217, he has a high risk of coronary stenosis.
