From: Myocardial contractility in the stress echo lab: from pathophysiological toy to clinical tool
Survival in patients with negative stress echo and different rest LV dysfunction. 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 cut-off value) in patient with moderate (left panel), severe (middle panel), or extreme (right panel) rest LV dysfunction.
