Figure 2 The extent of coronary artery disease for matched cohorts of coronary disease pretest risk subsets. The rate of no coronary disease (No CAD) is lower for patients undergoing direct cardiac catheterization. The rate of single vessel coronary disease (SVD) is comparable between the two diagnostic strategies. The rate of multivessel coronary disease (MVD) is higher in patients with evidence of ischemia on their initial stress perfusion scan and in those with a high pretest risk of coronary disease.
