Randomized Controlled Trial
Levosimendan versus dobutamine in heart failure patients treated chronically with carvedilol.
Although beta-blockers are highly effective in the treatment of heart failure (HF), many patients with HF receiving a beta-blocker continue to become decompensated and require hospitalization for worsening HF. Levosimendan and dobutamine are used to manage decompensated HF, but their comparative effects on left ventricular (LV) function in patients prescribed beta-blockers are unknown. ⋯ Dobutamine and levosimendan have different effects on LV functions in patients treated chronically with carvedilol. These differences should be considered when selecting inotropic therapy for decompensated HF receiving long-term carvedilol.
