No evidence of cardiac stunningor decoupling immediately after cardiopulmonary bypass for elective coronarysurgery.

There was no evidence for clinically relevant cardiac stunning or altered arterial load immediately after cardiopulmonary bypass for CABG surgery. The unchanged Ea/Ees ratio and OPF are indicating unchanged cardiac efficiency before and after cardiopulmonary bypass. This indicates that in elective CABG patients cardiovascular stunning is perhapsa phenomenon of inflammation and not immediate ischaemia-reperfusion injury or mechanical handling.
