The PVI, McGoon ratio, and Nakata index were measured and calculated.

There were five early deaths. The areas under the ROC curve for death were 0.89, 0.79, and 0.88 for the McGoon ratio, Nakata index, and PVI, respectively. A lower PVI better predicted prolonged postoperative hospital stay, cardiac intensive care unit stay, and ventilator time (Hazard Ratio, HR [95% Confidence intervals, CI]: 1.003 [1.002\u20131.004], <jats:italic>p<\/jats:italic> &amp;lt; 0.001; 1.002 [1.001\u20131.004], <jats:italic>p<\/jats:italic> &amp;lt; 0.001; 1.002 [1.001\u20131.003], <jats:italic>p<\/jats:italic> &amp;lt; 0.001, respectively) and was a significant risk factor for high 24 h max Vasoactive inotropic score (Crude Odds Ratio [OR] [95% CI]: \u22120.015 [\u22120.022, \u22120.007], <jats:italic>p<\/jats:italic> &amp;lt; 0.001), serous effusion (Crude OR [95% CI]: 0.996 [0.992\u20130.999], <jats:italic>p<\/jats:italic> = 0.020), delayed sternal closure (Crude OR [95% CI]: 0.983 [0.971\u20130.996], <jats:italic>p<\/jats:italic> = 0.010), and the need for peritoneal dialysis (Crude OR [95% CI]: 0.988 [0.980\u20130.996], <jats:italic>p<\/jats:italic> = 0.005).
