OBJECTIVE This study evaluated how much of the myocardium was hibernating in patients with left ventricle dysfunction and/or comorbidities who planned to undergo either surgical or interventional revascularization. Furthermore, this study also identified

According to estimates, up to 50% of patients with coronary artery disease and impaired left ventricular function have areas of viable myocardium. This dysfunctional, yet viable myocardial tissue, which can improve functionally after myocardial oxygen supply is reestablished, has been called hibernating myocardium.

Hibernating myocardium represents a chronic myocardial dysfunction at rest associated with reduced coronary perfusion. Although myocardial contraction is depressed, metabolic balance is maintained, myocytes remain viable and myocardial contraction can be restored with myocardial revascularization.

Hibernating Myocardium: A Review
Journal of Molecular and Cellular Cardiology, 1996Within a few seconds after a sudden reduction of coronary blood flow regional contractile dysfunction ensues. The mechanisms responsible for the rapid reduction in contractile function during acute myocardial ischemia remain unclear, but may involve a rise in inorganic phosphate.

The hibernating myocardium refers to resting LV dysfunction due to reduced coronary blood flow that can be partially or completely reversed by myocardial revascularization and/or by reducing myocardial oxygen demand. It is different from the stunned myocardium. Methods for its detection are not yet perfect.

Hibernating Myocardium: A Historical Perspective
Cardiovascular Drugs and Therapy, 1992Hibernating myocardium refers to the presence of persistent myocardial and left ventricular dysfunction at rest, associated with conditions of severely reduced coronary blood flow. This left ventricular dysfunction probably represents an adaptive mechanism preventing irreversible myocardial cell damage, since myocardial and left ventricular dysfunction

Hibernating myocardium in heart failure
Expert Review of Cardiovascular Therapy, 2005Ischemic left ventricular systolic dysfunction may result from myocardial necrosis or from hypocontractile areas of viable myocardium. In some cases, recovery of contractility may occur on revascularization--this reversibly dysfunctional tissue is commonly referred to as hibernating myocardium.

The pathology of hibernating myocardium
Nuclear Medicine Communications, 2002Myocardial hibernation represents a protective mechanism of muscle preservation in the setting of atherosclerotic coronary artery disease. Long-standing myocardial hypoperfusion leads to diminished myocardial contractility that reverses with improved blood flow after revascularization.

Hibernating myocardium, a clinical entity
Basic Research in Cardiology, 1995Before the term “hibernating myocardium” was introduced by Rahimtoola (1), it was shown by us that a subpopulation of patients could be defined who had a significant coronary artery stenosis and impaired wall motion in the absence of myocardial infarction (2).
