Survival in patients with negative stress echo according to the employed stress. Kaplan-Meier survival curves (considering combined death or HF hospitalization as an endpoint) in medically treated patients stratified according to the presence of stress end-systolic pressure-volume relation-based contractile reserve (ΔESPVR ≥ 0.4 mmHg/mL/m2 vs rest as cutoff value). Left panel, patients (n = 57) stratified according to exercise stress echo. Middle panel, patients (n = 165) stratified according to dipyridamole stress echo. Right panel, patients (n = 160) stratified according to dobutamine stress echo.
