Abstract

Myocardial hibernation denotes chronic ventricular dysfunction, regional and/or global, due to myocardial ischemia usually due to ischemic heart disease. A postulated mechanism may be relayed to subacute or chronic myocardial ischemia resulting from a reduction of coronary blood flow. Techniques to detect and quantitate the extent of viable myocardium may include nuclear imaging and 18-fluorodeoxyglucose positron emission tomography (FDG PET). When a sufficient amount of viable myocardium is present, surgical or percutaneous revascularization appears to be effective in relieving symptoms and improving left ventricular function and prognosis even in patients with a very low ejection fraction. Thus, detection of viable hibernating myocardium is highly desirable before revascularization is undertaken.
