Neurohumoral improvement and torsional dynamics in patients with heart failure after treatment with levosimendan
2015
article Background: Levosimendan improves clinical and hemodynamic parameters exerting an anti-inflammatory and antiapoptotic effect in decompensated heart failure. The aim of this study was to evaluate the effects of levosimendan on LV torsion, plasma levels of NT-proBNP and on the balance between pro-inflammatory (TNF-α, IL-6) and anti-inflammatory cytokines (IL-10). Methods: We enrolled 24 patients (age 62 ± 7 years) with acute HF, NYHA class IV and severe LV dysfunction. All patients underwent transthoracic echocardiography using two-dimensional speckle tracking analysis to detect LV twist angle (LVTA), at baseline and 1 week after treatment with levosimendan infusion. Biochemical parameters (pro-BNP, IL-6, IL-10, TNF-α) were determined by enzyme-linked immunosorbent (ELISA). Results: After one week, we observed an improvementinLV function especially inLVTA(4.15 ± 2.54 vs2.9 ± 2.1 p b 0.01), in LV ejection fraction (27.3 ± 8.04 vs 21.6 ± 6.8 p = 0.03) and also a significant reduction in BNP levels (1844 ± 560 vs 4713 ± 1050, p = 0.03). The multiple linear regression analysis showed a significant re- lationbetween areduction ofTNF α/IL-10 ratio (ΔN 20%)andBNP(ΔN 40%), LVEF(ΔN 10%)and LVTA(ΔN 20%) (O.R. 1.77, 95% C.I. 1.11-2.83; O.R. 1.49, 95% C.I. 1.08-2.67; O.R. 1.66, 95% C.I. 1.10-2.74, respectively, confirmed p, all b0.01 by Hosmer-Lemeshov confirmation and the formal test for interaction). Conclusions: Levosimendan exerts a hemodynamic effect by improving EF and LV torsion in patients with acute HF in association with a positive effect on the balance between pro and anti-inflammatory cytokines. © 2014 Published by Elsevier Ireland Ltd.
