 Glucose uptake in normal and ischemically jeopardized myocardium
Within the last 20 years, identification of viable myocardium in the clinical setting to predict outcome after CABG has been a field of intense clinical research in patients with chronic ischemic heart disease and impaired left ventricular contractile function.
Furthermore, the data suggested that surgery in patients with viable myocardium was associated with better survival compared to surgery in patients without viable myocardium.
Following coronary reperfusion the contractile function of the myocardium remains depressed for a prolonged period despite restoration of blood flow - a condition interpreted as "myocardial stunning" (Braunwald and Kloner 1982).

 PSYCHOLOGICAL REVIEW
Hibernating myocardium: clinical and functional response to revascularisation.
Knowledge that reversible changes and areas of viable myocardium can occur in patients with left ventricular dysfunction will assist healthcare providers in the care and management of patients with hibernating myocardium.
conclude that hibernating myocardium is not a completely adaptive response to underperfusion.

 Madrid Arrythmia and Myocardium
It is a paradox that at a time when progress is very rapid, practicing physicians have little time available for studying during his daily duties.
However, we believe that what patients need is that physicians taking care of them are able to provide the best possible diagnostic and therapeutic plan.
Therefore, during the Madrid Arrhythmia and Myocardium 2006, Memorial Symposiums and Workshops we will present new and future avenues in mechanical and electric heart disorders, and review the more practical aspects of the diagnosis, prevention, and treatment of arrhythmia and heart failure.

 Myocardium - Wikipedia, the free encyclopedia
Cardiac muscle, like other muscles, can contract, but it can also conduct electricity, like nerves.
The myocardium is composed of specialized cardiac muscle cells with an ability not possessed by muscle tissue elsewhere in the body.
Other tissues are the endocardium (inner lining, effectively a specialised endothelium) and the pericardium (a connective tissue layer around the heart).

Both of these studies greatly increase scintigraphic sensitivity in the evaluation for myocardial ischemia.

 eSynopsis of Dilatation of the Myocardium
•It is likely that any disease state that results in universal injury to the myocardium, such as anemia, is going to result in less effective fiber contraction, with incremental decreases in ejection fraction causing incremntal compensatory increases in fiber length, until an adequate ejection fraction is restored.
•The myocardium in cases of severe chronic anemia such as untreated pernicious anemia, classically showed fatty deposits within myocardial fibers appearing grossly as yellow stripe-like discolorations described as "tigering" because of the resemblance to tigers.
