VIS = vasoactive-inotropic score.
p < 0.003.
Vasoactive medication units: epinephrine (µg/kg/min), vasopressinU/kg/min), norepinephrine (µg/kg/min), milrinone (µg/kg/min), dopamine (µg/kg/min), and dobutamine (µg/kg/min).
Left ventricular ejection fraction < 30% severely depressed, 30–40% moderately depressed, 40–48% mildly depressed, and > 48% normal.
Hemodynamics were collected as a continuous variable and described as a median (interquartile range) or n (%).
