What does Myocardial Hibernation mean?

Q:
What does myocardial hibernation mean?

A:
Myocardial hibernation means that the myocardium has abnormal contractile functions. It causes irreversible left ventricular dysfunction.

Symptoms

Usually, the disease manifests itself in the setting of chronic ischemia, which may be reversible. If with the following clinic situation, one may expect myocardial hibernation:

  • Chronic stable angina
  • Unstable angina
  • Silent ischemia
  • After AMI

Treatment

With the help of echocardiography, cardiac magnetic resonance image (CMR), nuclear medicine or ventriculography, the abnormalities can be visualized. Generally, dobutamine can stimulate the patient’s contractile function.

Myocardial contractility recovers significantly in hibernating myocardium after successful revascularization. Depending on the duration and severity of ischemia, recovery period varies.
