End-Systolic Elastance and Ventricular-Arterial Coupling Reserve Predict Cardiac Events in Patients with Negative Stress Echocardiography
Figure 3
Scatter plot relating ventricular-arterial coupling ratio () and left-ventricular ejection fraction (LVEF). (a) Resting values; (b) peak stress values; (c) and LVEF reserve values. Green circles: patients with follow-up events. Blue circles: patients without follow-up events. : arterial elastance index; : LV end-systolic elastance index; : ventricular-arterial coupling ratio.
