End-Systolic Elastance and Ventricular-Arterial Coupling Reserve Predict Cardiac Events in Patients with Negative Stress Echocardiography
Figure 5
Ventricular-arterial coupling reserve, its components in patients with versus without follow-up events. Bars show changes from rest to peak stress (reserve) in the patients who underwent exercise (green bars), dipyridamole (yellow bars) and dobutamine (red bars) stress echocardiographies. (a) : LV end-systolic elastance index reserve; (b) : arterial elastance index reserve; and (c) : ventricular-arterial coupling ratio reserve.
