Abstract

Aims To evaluate the safety and efficacy of levosimendan in patients with left ventricular failure complicating acute myocardial infarction.

Methods and Results Levosimendan at different doses (0·1–0·4μg.kg−1.min−1) or placebo were administered intravenously for 6h to 504 patients in a randomised, placebo-controlled, double-blind study. The primary end-point was hypotension or myocardial ischaemia of clinical significance adjudicated by an independent Safety Committee. Secondary end-points included risk of death and worsening heart failure, symptoms of heart failure and all-cause mortality. The incidence of ischaemia and/or hypotension was similar in all treatment groups (P=0·319). A higher frequency of ischaemia and/or hypotension was only seen in the highest levosimendan dose group. Levosimendan-treated patients experienced lower risk of death and worsening heart failure than patients receiving placebo, during both the 6h infusion (2·0% vs 5·9%; P=0·033) and over 24h (4·0% vs 8·8%; P=0·044). Mortality was lower with levosimendan compared with placebo at 14 days (11·7% vs 19·6%; hazard ratio 0·56 [95% CI 0·33–0·95];P =0·031) and the reduction was maintained at the 180-day retrospective follow-up (22·6% vs 31·4%; 0·67 [0·45-1·00],P =0·053).

Conclusions Levosimendan at doses 0·1–0·2μg.kg−1.min−1 did not induce hypotension or ischaemia and reduced the risk of worsening heart failure and death in patients with left ventricular failure complicating acute myocardial infarction.
