Heart failure & cardiomyopathies
The possible impact of levosimendan infusions on clinical course of heart failure: the results of the LEIA-HF study
- prematurely terminated
Authors' conclusion
In a selected group of stable ambulatory advanced HF (left ventricular ejection fraction ≤35%, New York Heart Association Classes III and IV) patients, repetitive levosimendan 24 h infusion might be an additional therapeutic option but observed deaths may raise its safety issue.
Study context
- Population
- Patients with ambulatory stable advanced heart failure (HF) (left ventricular ejection fraction ≤35%, New York Heart Association Classes III and IV)out of 350 planned
- Participants
- 64 patients
- Comparison
- Intermittent levosimendan vs placebo
- Levosimendan group (study group)n = 34
- Placebo groupn = 30
- Primary endpoint
- Death from any cause or unplanned hospitalization for HF, whichever occurred first
- Follow-up
- 12-month follow-up period
Methodological detailsnine centres around Poland
- Nine centres around Poland
Primary result
As reported in the abstract
P = 0.14
Further findings
N-terminal pro-B-type natriuretic peptide concentrations in the study group
- Significant decrease
- 5084 pg/ml (306-23.203) vs 2027 pg/ml (872-2174), P = .02
Left ventricular ejection fraction in the study group
- Improvement
- 20.9 ± 5.9% vs 29.27 ± 5.23%, P = .015
Study conduct
- The study was prematurely terminated due to excess of deaths in the active treatment group
Safety
