p < 0.01 for comparison of Algorithms A and B. Description of Algorithms A and B is provided in Figure 1.

CABG = coronary artery bypass graft; CAD = coronary artery disease; LAD = left anterior descending; LCX = left circumflex artery; NPV = negative predictive value; PCI = percutaneous coronary intervention; PPV = positive predictive value; RCA = right coronary artery.
