Background: Intravenous levosimendan improves symptoms in acutely decompensated heart failure.
Aims: To evaluate the effects of oral levosimendan in severe chronic heart failure (CHF).
Methods: 307 patients with NYHA IIIB–IV CHF were randomly assigned, double-blind, to levosimendan 1 mg once or twice daily or placebo for at least 180 days. An exploratory primary end-point, the Patient Journey, a composite consisting of repeated symptom assessments, worsening heart failure and mortality during 60 days was used. Minnesota Living with Heart Failure quality of life score (MLHFQoL) and NT-proBNP were assessed repeatedly.
Results: Patients assigned to a lower dose of levosimendan had more severe CHF at baseline. No differences in symptoms emerged and worsening heart failure events and death were similar resulting in a similar Patient Journey score with levosimendan and placebo (p=0.567). Compared to placebo, a net improvement of 3–4 points in MLHFQoL at several time-points in favour of the combined levosimendan groups was observed (p<0.001) which was accompanied by a substantial and persistent reduction in NT-proBNP (–30–40%) (p<0.001).
Conclusion: Levosimendan improved QoL and decreased NT-proBNP but did not improve the Patient Journey composite in patients with severe CHF. Further research with this compound is warranted to clarify safety and efficacy.
