Clinical TrialThe influence of beta-blockade on the hemodynamic effects of levosimendan in elderly (>or= 70 years) patients with acutely decompensated systolic heart failure.
The purpose of this study was to evaluate the influence of chronic beta-blockade on the hemodynamic parameters in elderly (>or= 70 years) patients with acutely decompensated systolic heart failure treated with levosimendan. Eighteen patients with acutely decompensated systolic heart failure (8 on chronic beta-blockade) were included in this study. Inclusion criteria were symptoms and signs of acute heart failure in the presence of: a) left ventricular ejection fraction < 0.35; b) cardiac index < 2.5 l/min/m2, c) pulmonary capillary wedge pressure > 15 mmHg; and d) systolic blood pressure between 90 and 110 mmHg. ⋯ Treatment with levosimendan was associated with an increase in the cardiac index and a decrease in wedge pressure in both groups (Group A: 43.8% and 33%; p < 0.001 vs. baseline; Group B: 17.72% and 17.5%, p < 0.001 vs. baseline, respectively). Peripheral and pulmonary resistance significantly decreased in both groups (31% vs. 15%, p < 0.001 and 44.5% vs. 25%, p < 0.001, respectively). Thus, the beneficial hemodynamic effects of levosimendan are maintained in elderly patients with acute decompensated systolic heart failure treated with beta-blockers.
