Figure Legends:
Figure 1. LVOT pulsed wave Doppler tracing at rest and post peak
exercise, used to calculate the normal ΔSV response to exercise
and subsequent estimation of VTI.
Figure 2. LVOT pulsed wave Doppler tracing at rest and post peak
exertion, used to calculate the abnormal ΔSV response to
exercise and subsequent estimation of VTI.
Figure 3. ROC analysis for the derivation cohort to determine the
cut-off value for ΔSV.
Figure 4. ROC analysis showing that ΔSV is more discriminative than
ΔSVi and to
determine the cut-off value for ΔSV
Figure 5. Histogram of the distribution of ΔSV for the Ischemic and
Non-Ischemic patients in the validation cohort.
Figure 6. Kaplan Meier curves for the combined cardiac adverse event by
Stroke Volume response to exercise in the validation cohort
Figure 7. Kaplan Meier curves for the combined cardiac adverse event by
Stroke Volume response to exercise for all non-ischemic stress
echocardiograms in the validation cohort (n=1000)
