Figure 4 Receiver-Operator Curves of Changes in LVESV During BEE and Detection of CAD

Graphs showing sensitivity and specificity according to various cutoff values of percent change of left ventricular end-systolic volume (LVESV) for the detection of coronary artery disease (CAD). (Left) Percent change in LVESV from baseline to peak stage. (Right) Percent change from smallest LVESV in intermediate stages to peak exercise (Ex). AUC = area under the curve; BEE = bicycle exercise echocardiography.
