Effect of levosimendan on E/E' ratio in patients with ischemic heart failure.
Levosimendan is a novel positive inotropic calcium sensitizer agent used in acute heart failure. In acute heart failure, it improves hemodynamic parameters more favorably than the conventional positive inotropes. In this study, the effect levosimendan on E/E' ratio as a non-invasive indicator of LV filling pressure was evaluated compared to dobutamine in a prospective, randomized, patient-blind manner. ⋯ Levosimendan causes a greater reduction of E/E' ratio compared to dobutamine in acute systolic left heart failure. This may explain the more favorable hemodynamic effects of levosimendan when compared to conventional positive inotropics in patients with systolic left heart failure.
