Figure 4: Receiver-operating-characteristic curves and the corresponding areas under the curve (AUC) shows the predictor performance of ventricular-arterial coupling reserve, its components and hemodynamic changes (Δ) during stress in the exercise (EX), dipyridamole (DIP), and dobutamine (DOB) subsets. CI: cardiac Index; : arterial elastance index; : LV end-systolic elastance index; : ventricular-arterial coupling ratio; LVEF: left ventricular ejection fraction; and PVA: pressure-volume area.
