Table 4 ESE parameters and normal values
From: Cardiopulmonary exercise testing and echocardiographic exam: an useful interaction
Variables | Meaning | Normal values |
|---|---|---|
Δ LVEF | Contractile reserve | > 5% |
ΔGLS | Contractile reserve | > 2% |
ΔSV | Contractile reserve | >  20% |
Peak E/e’ | Elevated LV filling pressure during stress | > 15 |
Peak PAPs | Maximal pulmonary systolic pressure during stress | >  60 mmHg |
ΔEROA | Changes in mitral regurgitation severity during time | < 10 mm3 |
ΔTransmitral MPG | Changes in transmitral pressure gradient during stress | < 15 mmHg |
ΔTransaortic MPG | Changes in transaortic pressure gradient during stress | <  20 mmHg |
LVOT Maximal Peak Gradient | In case of LVOT obstruction it reflects pathological | < 50 mmHg – low prognostic impact |
