Figure 3.

Bar graph showing the ΔLVEF of the two groups. On day 7, there was no significance between the levosimendan and the non-levosimendan groups (median 30.8%, IQR −4.4 to 63.5% vs. median 15.1%, IQR −3.5 to 40.0%, respectively). In addition, no significant difference was revealed at their follow-up (median 123.5%, IQR 56.1–226.0% vs. median 80.0%, IQR 36.4–131.3%). LVEF, left ventricular ejection fraction; NS, no significance; POD, postoperation.
