Abstract

Objectives Calcium sensitizers have been shown to improve outcomes in patients with low cardiac output syndrome (LCOS) after cardiac surgery. We assessed the effects of levosimendan on LCOS in cardiac surgical patients to identify outcome predictors. Methods A total of 106 patients in whom LCOS persisted despite conventional therapy additionally received 0.1 mu g/kg/min of levosimendan for 24 hours according to a defined treatment algorithm. Baseline and treatment data as well as hemodynamic and outcome parameters were compared between survivors and nonsurvivors, and a multivariate correlation and regression tree analysis was implemented. Results The ejection fraction significantly increased from 27% +/- 4% to 38% +/- 8% within 24 hours and to 45% +/- 10% within 48 hours of starting levosimendan. These changes were accompanied by a significant increase in cardiac output from 5.2 +/- 0.6 to 6.2 +/- 0.7 L/min within 24 hours and significant dose reductions in vasopressors and inotropes. In contrast to nonsurvivors, survivors' need for inotropic support decreased after the addition of levosimendan to the therapy. Conclusion In our patients, all of whom were treated according to the same algorithm, the response to levosimendan in terms of the post-levosimendan need for inotropes and vasopressors predicted survival.
