Coronary CT and Calcium scoring
Application of Coronary Calcium in Symptomatic Individuals
The presence or absence of coronary calcium can significantly alter the posterior probability of CAD for individuals presenting with chest pain. The calculator below shows how these probabilities are affected and computes similar data for exercise treadmill testing. Note that coronary calcium compares favorably with exercise testing for evaluation of chest pain syndromes and often has a higher negative predictive value, especially in women were exercise treadmill testing is known to be weak.
