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.
