Summary
Left ventricular outflow tract velocity time integral (LVOT-VTI) is a Doppler-derived measure of the distance traveled by midstream blood through the left ventricular outflow tract (i.e., stroke distance) and it is a useful surrogate marker of CO and global ventricular performance. The aim of this study is to assess, in a context of acute care, the predictive value of VTI-LVOT on clinical endpoints such as: in-hospital mortality, acute kidney injury (AKI), onset of cardiogenic shock, use of amines and vasopressors, occurrence of delirium, MOF and sepsis, respiratory distress requiring the use of invasive and non-invasive mechanical ventilation.
