In [[cardiology]] '''hibernating myocardium''' is a state when some segments
of the [[myocardium]] exhibit abnormalities of contractile function. These
abnormalities can be visualised during [[echocardiography]] or [[ventriculography]]. The wall of the affected segments is hypo-, a- or dyskinetic.
The phenomenon is highly significant clinically because it usually
manifests itself in setting of chronic [[ischemia]], which is potentially reversible by [[Revascularization|revascularisation]]. The regions of myocardium are still viable and can restore its function. There develops a new steady state between myocardial blood flow (MBF) and myocardial function, MBF reduced and in consequence function is reduced too.
The clinical situations where one can expect hibernating myocardium are:
*chronic stable [[Angina pectoris|angina]]
*unstable angina
*silent ischemia
*after [[AMI]]
