Relationships between global longitudinal strain (GLS) and left ventricular (LV) end-diastolic pressure (LVEDP, A), LV mean diastolic pressure (LVMDP, B), the time constant of LV isovolumic relaxation (τ, C), slope of end-diastolic pressure volume relationship (EDPVR, D), mean e´ (E), E/e´ (F). CI, confidence interval; EF, ejection fraction.
