In cardiology<unk>  is a state when some segments of the<unk>  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 revascularisation. The regions of<unk>  are still viable and can restore its function. There develops a new steady state between myocardial blood flow and myocardial function, myocardial blood flow reduced and in consequence function is reduced too.
The clinical situations where one can expect<unk>  are:
chronic stable angina pectoris
unstable angina
silent ischemia
after AMI
Hibernating myocardium
Postinfarction conduction abnormalities
Post-infarction conduction abnormalities
Coronary artery ulceration
Tachycardia induced cardiomyopathy
Multivessel coronary artery disease
Adrenergic myocarditis
Cardiac fibrosis
