1
Left ventricular ejection fraction (LVEF) has limitations in critically ill patients due to variability and dependence on loading conditions.
-
2
Global longitudinal strain (GLS), mitral annular plane systolic excursion (MAPSE), and tissue Doppler-derived systolic velocity (S’) may provide better assessments of systolic function.
-
3
Impaired GLS is associated with increased mortality in patients with sepsis and COVID-19, confirmed by a recent meta-analysis.
-
4
The study aims to evaluate the clinical utility of GLS, MAPSE, and S’ in critically ill patients and their prognostic value for 90-day mortality.

Echocardiographic examinations were performed within 24 hours of ICU admission, following initial cardiovascular stabilization and volume resuscitation.
