The role of left ventricular ejection fraction and left ventricular outflow tract velocity-time integral in assessing cardiovascular impairment in septic shock

HIGHLIGHTS

SUMMARY

    Both LVEF and LVOT VTI have been used for prognostic reasons in sepsis with studies reporting that lower LVEFs but higher VTIs are associated with increased survival. Given that reference values for LVEF and VTI are standardized for normal afterload, the role of these indices in septic shock still remains challenging. This prospective study aimed to evaluate the correlation between LVEF and LVOT VTI to SVR values as assessed by Pulse index Continuous Cardiac Output (PiCCO) thermodilution method, seeking for "reference" or "predicted" echocardiographic values for given SVR in septic shock. The authors hypothesized . . .
