Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: We hypotize that levosimendan, delivered together with cardioplegia, can improve LV dysfunction after opening of aortic cross-clamp in patients undergoing aortic valve and coronary artery bypass operation. Our primary endpoint is a change in cardiac output 15 min after separation from cardiopulmonary bypass (CPB) compared to the baseline (after induction of anesthesia).;Secondary Objective: ;Primary end point(s): Our primary endpoint is a change in cardiac output 15 min after separation from cardiopulmonary bypass compared to the baseline (after induction of anesthesia). | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 15 min after separation from cardiopulmonary bypass;Timepoint(s) of evaluation of this end point: Secondary endpoints are a change in LV ejection fraction from baseline ((after induction of anesthesia) to 5 min after sternal closure and cTnT/CK-MB on the first postoperative morning. | — |
