To rule out hibernating myocardium, a thallium viability scan was performed which showed a fixed inferoseptal and apical perfusion abnormality with no redistribution in 24-hour delayed imaging.
We had a similar outcome, probably because those patients had less hibernating myocardium and less development of coronary collaterals than that of older patients.[sup][13],[14]
Positive control of cardiac failure can reduce the risk of myocardial ischemia, rescue hibernating myocardium and viable myocardium, improve cardiac function, and enhance recovery rate.5
On the other hand, if the heart fails to recover promptly, then the myocardium is in a more persistent LV dysfunction, termed hibernating myocardium (Burton et al., 2009a).
Areas of myocardial dysfunction without fibrotic scarring are common in patients with heart failure from coronary artery disease and that they arise from remodeling in response to a heart attack, as well as adaptations that develop from periods of inadequate blood flow, sometimes called hibernating myocardium.
He proposed the concept that areas of "hibernating myocardium" exist in the ischemic ventricle that can be revived by restoring its blood supply by CABG.
