Background: In advanced chronic heart failure (CHF) 20% of patients do not tolerate beta-blockers and 50% do not reach target doses.
Aim: To test whether levosimendan or prostaglandin E1 (PGE1) can facilitate uptitration of beta-blockers in advanced CHF.
Methods and results: Seventy-five advanced CHF patients (LVEF<35%, NYHA class IIIb or IV) intolerant to beta-blocker uptitration to target doses (10 mg bisoprolol/day) were randomised to a monthly 24 h infusion with levosimendan (n=39) or a chronic infusion with PGE1 (n=36) for 3 months. Bisoprolol was uptitrated following predefined criteria. At 12 weeks, bisoprolol dose increased from 4 mg to 10 mg in both groups. Heart failure worsening occurred in 29 levosimendan patients (74%) versus 16 PGE1 patients (44%, p=0.008). Uptitration was impossible in 9 levosimendan patients (23%) versus 2 PGE1 patients (6%, p=0.03). The combined endpoint of death or urgent heart transplantation or implantation of a ventricular assist device was reached by 12 levosimendan patients (31%) versus 4 PGE1 patients (11%, p=0.04). After 1 year, LVEF increased from 23±7% to 28±11% (p=0.0004), and BNP decreased from 994±806 to 659±564 pg/ml (p=0.03).
Conclusion: Levosimendan and PGE1 facilitate uptitration of beta-blockers in previously intolerant CHF patients. PGE1 treatment allowed uptitration in more patients and resulted in a better clinical outcome compared to levosimendan. This approach increased LVEF and decreased BNP after 1 year.
