[The hibernating myocardium--its use in clinical practice].

: Hibernated myocardium is a term used to describe a state of myocardial hypocontractility which is due to chronic hypoperfusion of the heart muscle. The myocardium remains, however, viable and therefore revascularization can significantly improve the reduced mechanical function of the left ventricle. Differentiation between hibernated myocardium and a myocardium which was irreversibly damaged and replaced by scar tissue is particularly important in patients with ischemic dysfunction of the left ventricle. Information on the viability of dysfunctional areas of the myocardium helps in reflections on the indication and strategy of the revascularization operation.
