Hibernating myocardium

Hibernating myocardium

In cardiology hibernating myocardium is a state when some segmentsof the myocardium exhibit abnormalities of contractile function. Theseabnormalities 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 usuallymanifests itself in setting of chronic ischemia, which is potentially reversible by 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
*unstable angina
*silent ischemia
*after AMI

ee also

*stunned myocardium
*myocardial scarring
