  • Prevalence of CAD percentage in a class. Within parentheses is the percentage of the population in this class. Prevalence of CAD in the total CVC population is 16%.

  • Green: effective risk for CAD <5%, excluding CAD without further testing; yellow: effective risk for CAD 5%–70%, requiring further non-invasive testing; orange: effective risk of CAD >70%, requiring direct invasive angiography. No model provided a group with sufficient prevalence to make the diagnosis of CAD (ie, >85%).

  • CAD, coronary artery disease; CAD2, CAD consortium clinical; CVC, cardiovascular clinic; ESC, European Society of Cardiology; MPA, memetic pattern-based algorithm; n.a., not applicable; PTP, pretest probability.
