Clinical outcomes of levosimendan versus dobutamine in patients with acute decompensated heart failure with reduced ejection fraction and impaired renal function.

To assess the clinical outcomes of levosimendan and dobutamine in patients with acute decompensated heart failure with reduced ejection fraction and impaired renal function in Indian scenario. Cardiac, renal, electrolytes and hepatic parameters as well as the clinical outcomes were assessed. Levosimendan and dobutamine improved ejection fraction significantly. Levosimendan in comparison to dobutamine, increased cardiac output (0.76 vs. -0.38 at 48 h, 1.15 vs. -0.31 day 7, -2.02 vs. -1.51 day 30), cardiac index (0.89 vs.-0.13 at 48 h, 1.16 vs. -0.07 at day 7 and 1.05 vs. -0.25 at day 30) and eGFR (-1.4 vs. -0.75 at day 30) significantly. Levosimendan reduced ICU stay (p = 0.038) significantly whereas dobutamine decreased the hospital stay duration (p = 0.015). There was no major difference in re-hospitalization and mortality between groups. Ventricular tachyarrhythmia was the main adverse event noted in Levosimendan arm. Levosimendan showed improved cardiac as well as renal outcomes within a month when compared to dobutamine and it is the first study to determine the renal parameters of Levosimendan in an Indian setting.
