    Abstract:
    INTRODUCTION: Levosimendan is an inodilatory drug with hemodynamic effects in patients with decompensated chronic heart failure. AIM: Short-term (one month) evaluation of clinical, hemodynamic and neurohormonal changes in patients with decompensated chronic heart failure undergoing levosimendan therapy. METHODS: Twenty-six (21 male) consecutive patients were studied, corresponding to 32 levosimendan administrations (bolus + 24h infusion), aged 56.7+/-13.0 years, with decompensated chronic heart failure, in NYHA functional class III-IV (78.1% in class IV), and cardiac index (CI) <2.5 l/min/m2. Clinical (NYHA class), non-invasive hemodynamic (echocardiography) and neurohormonal (Elecsys ECLIA NT-ProBNP) evaluations were performed before levosimendan administration and on days 1, 4, 10 and 30. RESULTS: 1) Until day 10, there was a progressive decrease in NT-ProBNP values and weight (p<0.001), with an increase in CI (p<0.001); 2) NYHA functional class improved progressively, with 76% of the patients in NYHA class II at day 30; 3) NT-ProBNP values at day 1 correlated inversely (r=-0.414; p=0.024) with CI at day 4; and 4) the absolute decrease in NT-ProBNP values at day 4 (relative to baseline values) correlated with weight loss at day 4 (r=0.495, p=0.005), day 10 (r=0.424, p=0.031) and day 30 (r=0.486, p=0.030). CONCLUSION: Levosimendan therapy in patients with decompensated chronic heart failure contributes to progressive NYHA class improvement. The variations seen in NYHA class and hemodynamics was reflected in changes in NT-ProBNP.
