Oxidative stress plays a key role in the development of heart failure. The study is a phase III, single-centre,
randomized, double-blind, clinical trial that assesses the influence of early intravenous levosimendan
administration in patients with decompensated CHF on oxidative stress parameters and the function of
enzymatic antioxidative mechanisms. A total of 50 patients with diagnosed CHF with reduced ejection
fraction, LVEF ≤ 35% are randomized in a 1:1 ratio to receive either levosimendan or dobutamine. The
hypothesis is that levosimendan in patients with decompensated heart failure may reduce ROS production
and/or enhance antioxidant protection. MDA and LPO concentrations and the activity of antioxidant
enzymes SOD, GPX, GR, and CAT will be measured in plasma samples.
