Acute and Advanced Heart Failure Blog

Professor Gerhard Pölzl is Chief of the Heart Failure and Heart Transplant Program at the Medical University Innsbruck. His research is focused on clinical studies in advanced and chronic heart failure and on translational studies in cardiomyopathies.

He has been Principal Investigator of the LevoRep clinical trial that tested the efficacy and safety of pulsed infusions of levosimendan in outpatients with advanced heart failure. He is now P.I. of the clinical trial LEODOR, on repetitive use of levosimendan in advanced heart failure.

This blog is focused on the therapeutic options for Acute and Advanced Heart Failure:  new data, new studies, new opinions,  new trends.

ESC 2017 in Barcelona

The annual congress of the European Society of Cardiology (in Barcelona, from the 26th to the 30th of August) was a unique occasion for updating our knowledge on Acute and Advanced Heart Failure. At “Village 9” the sessions were focused on Heart Failure, with insights on Pathophysiology and mechanisms, Epidemiology, prognosis and outcome, ventricular function & hemodynamics, Drug treatment, etc. Also in some of the very popular “Hubs” the sessions were often touching intriguing themes such “Can we teach heart failure drugs new tricks?”. Several Pharmaceutical Industries had organized either satellite symposia or series tutorials to complement the general program, and the daily agendas of the attendees went easily overbooked. In the field of Advanced Heart Failure, a series of hands-on tutorials was organized by Orion Pharma on the use of inodilators. The three days program included lectures by 14 European speakers (from Spain, Italy, Germany, France, Greece, Austria, Finland, and Russia) on the use of inodilators for correcting hemodynamic dysfunction and ameliorating symptoms in patients with advanced heart failure. Their main conclusion was that the calcium sensitizer and potassium channel opener drug family can be considered as a safe solution to achieve inodilation. 

Also the poster session was rich and stimulating. To be noticed, the first report of the RELEVANT-HF clinical trial on repetitive levosimendan in advanced refractory heart failure was presented by the Italian group of Prof. Fabrizio Oliva.  They concluded that, in patients with ARHF, scheduled repeated LEVO infusions resulted in a decrease in hospital admissions for worsening HF, expressed as proportion of days spent in hospital in the 6 months after with respect to the 6 months before start of planned treatment.

Finally, the Investigator Meeting of the LEODOR study (Repetitive Levosimendan infusions for patients with advanced chronic heart failure) was also held in Barcelona in occasion of the ESC congress. The study just started and over 30 centers are currently enrolling.

LION-Heart and LAICA clinical trials: differences and similarities


Advanced heart failure (AdHF) is associated with high morbidity and mortality and imposes considerable burdens on the health systems of developed countries. The LION-HEART ( NCT01536132) and LAICA (NCT00988806) trials are part of a suite of clinical studies of intermittent levosimendan therapy in this setting.


The LION-HEART trial evaluated the safety and efficacy of repetitive 6-h doses of levosimendan (0.2 micrograms/kg/min) every 2 weeks, as compared to placebo. The primary endpoint is the change in NT-proBNP levels between baseline 12 weeks later in a population of 69 adult patients with left ventricular ejection fraction <35%a and diagnostic criteria of advanced chronic heart failure.


The LAICA study assessed the effects of intermittent levosimendan 0.1 micrograms/kg/min every 30 days for a year) on combined overall mortality rate and hospital admission rate for acute cardiac decompensation or HF worsening in 213 adults with AdHF of any etiology, including at least one admission for acute decompensation within 6 months prior to randomization. Sub-studies were planned to examine effects on renal function and the cost-effectiveness of levosimendan.


Both these Phase 4 trials, conducted in Spain, are double-blind and placebo-controlled. LION-HEART has a smaller patient population but is powered for its primary focuses on NT-proBNP levels, which are indicative of heart failure status. The larger LAICA trial emphasizes widely-accepted and established clinical and health-related quality of life outcomes. The results were presented in Seville (ESC-HF 2015) and Florence (ESC-HF 2016), respectively, and provide insights into the usefulness, effectiveness and safety of intermittent levosimendan as an addition to the pharmacological repertoire for advanced heart failure.

Heart failure is the leading cause of adult hospitalization in the industrialized world and imposes a substantial burden on the public health. The later stages of heart failure are characterized by a steady decline in quality of life and frequent re-hospitalization for recurrent acutization of the symptoms.1 Most of the re-hospitalizations take place relatively soon after discharge from the index hospitalization. About one quarter of patients are re-hospitalized within one month, and more than 60% of these re-hospitalizations are seen within 15 days after discharge.2

Several clinical studies have been performed on the repetitive use of intravenous levosimendan in Advanced Heart Failure.3 Their results are suggesting that repeated infusions of levosimendan bring advantages to patients with advanced chronic heart failure, both as it regards mortality4 and re-hospitalization.5 However, few of these studies were properly powered. Therefore, a larger study is needed to verify the favorable results.

In the newly commenced LEODOR study ( the efficacy and safety of intermittent levosimendan therapy started during the vulnerable phase after a recent hospitalization for heart failure is tested. The hypothesis is that, compared with placebo, repetitive administration of levosimendan in the post-acute heart failure syndrome discharge period, will be associated with greater clinical stability through 14 weeks as assessed by a composite clinical endpoint consisting of mortality, acute heart failure episodes, and change in natriuretic peptide levels.
