Hibernating myocardium is hypoperfused

Basic Research in Cardiology, 1997
An increasing body of cumulative evidence has documented that HM is associated with or can be induced by a reduction of MBF. HM has also been shown to improve/normalize after revascularization.

Hibernating Myocardium: Diagnosis and Patient Outcomes

Current Problems in Cardiology, 2007
Approximately 50% of the patients with chronic obstructive coronary artery disease resulting in chronic contractile dysfunction have hibernating myocardium and may benefit from revascularization. This pooled analysis describes the relative merits of dobutamine echocardiography, thallium-201 and technetium-99m scintigraphy, positron emission tomography,

Stunned and Hibernating Myocardium

Journal of Cardiovascular Pharmacology, 1992
There are several potential outcomes of myocardial ischemia. When ischemia is severe and prolonged, irreversible damage occurs and there is no recovery of contractile function. When myocardial ischemia is less severe but still prolonged, myocytes may remain viable but exhibit depressed contractile function.

Hibernating myocardium: a brief article

Basic Research in Cardiology, 1995
Hibernating myocardium is a state of persistently impaired myocardial and left ventricular (LV) function at rest due to reduced coronary blood flow that can be partially or completely restored to normal if the myocardial oxygen supply/demand relationship is favorably altered, either by improving blood flow and/or by reducing demand.

Searching for Hibernating Myocardium

Circulation, 1996
He wakes, he lives, 'tis death is dead not he. —Percy Bysshe Shelly In the early 1980s, development of clinical methods for coronary revascularization (CABG/PTCA) was rapidly followed by presentation of data that indicated that dysfunctional myocardial segments supplied by vessels with reduced or seemingly absent flow could often recover function ...

“Hibernating Myocardium”: A Confusing Term?

New England Journal of Medicine, 1999
To the Editor: The process of hibernation, the “winter sleep of warm-blooded animals,” is a physiologic mechanism of self-protection that remains little understood. Webster's New World Dictionary defines hibernate as “to pass the winter in a torpid state.”1 The Oxford English Dictionary describes hibernation as “the action of wintering, or passing the ...

Clinical Aspects of Hibernating Myocardium

Journal of Molecular and Cellular Cardiology, 1996
Hibernating myocardium is a condition that is characterized by persistently impaired myocardial and left ventricular function at rest resulting from reduced myocardial blood flow. It is a result of adaptation or from downregulation. It may occur in unstable and chronic stable angina, acute myocardial infarction, and LV dysfunction and congestive heart ...

Stunned Myocardium and Hibernating Myocardium: Pathophysiology

2001
The first observations on the effects of decreased blood flow on myocardial contractility were made by Tennant and Wigers in 1935 in coronary occlusion experiments [1]. The relationships between the duration and severity of the ischaemia and their functional, biochemical and structural consequences have been established much more recently only when ...

Contractile pattern in acutely hibernating myocardium

Basic Research in Cardiology, 1995
In the hibernating myocardium contractile function and energy consumption are downregulated in response to reduced coronary blood flow (2, 4, 7 – 9). Thus, the myocardium may survive prolonged periods of reduced blood flow without overt signs of ischemia, and it may regain normal contractile function when blood flow restrictions are terminated.
