Documents systolic inefficiency in stunned rabbit hearts; leaves open translation to human post-ischemic recovery.
Does a 20-minute no-flow ischaemia alter the haemodynamic and energetic properties in isolated rabbit hearts?
Myocardial stunning following brief ischemia is characterized by decreased systolic and diastolic function, increased ventricular stiffness, and reduced mechanical efficiency despite maintained oxygen consumption.
Schipke et al. (1996) studied this question.
