Regional wall motion abnormalities in stunned and hibernating myocardium.
The clinical recognition that chronic dysfunctioning myocardial segments may retain viable myocardium has important therapeutic consequences. 'Stunned myocardium' and 'hibernating myocardium' have been proposed to distinguish respectively between post-ischaemic left ventricular dysfunction, a condition which normalizes spontaneously, and persistent wall motion abnormalities due to chronic hypoperfusion. This study examines the possible link between these two conditions.
