WebSome degree of myocardial stunning occurs in all patients after cardiac surgery.14 However, severe postoperative stunning is likely when: (1) CPB is complicated or greatly prolonged; (2) severe myocardial ischemia was present preoperatively. With acute dysfunction, ejection fraction is reduced but ventricular volumes may be relatively normal. WebIf this is viewed in terms of perfusion–contraction matching, then it is clear that myocardium which at one time point is by definition “stunned” may at another time point be hypoperfused and therefore “hibernating” without there ever being any alteration in the amplitude of contraction (see legend to fig 1 ).
