Myocardial Hibernation

Abstract

Myocardial hibernation signifies the existence of dysfunctional myocardium in vascular territories subtended by a stenotic coronary artery. No appreciable cardiomyocite loss is found. Resting or hyperemic flow is reduced. Its contractility can be improved after revascularization. Many non-invasive techniques (stress echocardiography, SPECT, PET, CMR) are being employed to a test the existence of HIB. It is generally believed that if more than 25% of left ventricular myocardium is found viable, revascularization is advisable.

However, the results of the STICH trial have shed some doubt which is still being debated.
