In this situation there are two explanations, an infarct or hibernating myocardium
The researchers cleverly circumvented the problem of having no human survivors to study by creating the hibernating myocardium
phenomenon in the first animal model--a pig--for the disease, and implanting a defibrillator similar to that used in patients with advanced heart disease.
Myocardial cell death and apoptosis in hibernating myocardium
is the term used to refer to segments rendered dysfunctional secondary to chronic ischemia.
A metaanalysis of studies involving 3,088 patients with comorbid heart failure and coronary artery disease indicated that patients with viable but hibernating myocardium
have a significantly lower mortality rate after revascularization than do patients with nonviable myocardium (J.
The purpose of viability assessment is to detect hibernating myocardium
in patients with left ventricular dysfunction and identify those who may have improved outcomes after revascularization (38, 39).
