Brief Summary:
The purpose of this study protocol is to evaluate the blood concentrations of levosimendan when administered at different doses clinically employed during cardiopulmonary bypass or cardiac manipulation during off pump surgery in patients who require the drug for inotropic support (improved heart function) and the associated hemodynamic variables (vital signs). Levosimendan is one of the first agents in a new class of drugs used to treat heart failure and works via a unique mechanism called calcium sensitization, that makes the heart beat more efficiently. Levosimendan also has unique effects on the blood vessels, as well as causing relaxation, an important therapeutic approach of heart failure therapy.

Condition or disease Intervention/treatment Phase
Heart Failure Drug: Levosimendan Phase 3

Detailed Description:
This is a non-randomized trial, and the patients will be assigned to one of three dose groups following cardiopulmonary bypass or prior to manipulation of the heart in the off pump group. A total of 30 patients will be enrolled into this study, 20 off-pump and 10 subjects on pump. Levosimendan is approved in Europe for the treatment of decompensated heart failure. It improved cardiac function without increasing energy demands. The subject's enrollment ends at Day 7 or day of discharge, whichever comes first.
