Survival-probability curves for propensity-score-adjusted Cox regression analysis for use of dobutamine (dashed line) and levosimendan (solid line) with noradrenaline. Adjusted for logit of the propensity score, which was estimated with the following variables: age, gender, medical history (myocardial infarction, coronary artery bypass graft surgery, hypertension, renal insufficiency), CS of acute coronary syndrome etiology, resuscitation prior to inclusion and initial presentation (confusion, blood lactate, creatinine, systolic blood pressure, sinus rhythm, and left ventricular ejection fraction). Of note, patients who received both dobutamine and levosimendan, or adrenaline were excluded. NS not significant
