Preconditioning Myocardium with Ischemia
Cardiovascular Drugs and Therapy, 1991Preconditioning and stunning are the chief adaptive changes induced in myocardium by a brief episode of reversible ischemia followed by arterial reperfusion. In the dog heart, both coexist for a period of at least 20 minutes of reperfusion, but after 120 minutes of reflow, preconditioning is much diminished, while stunning remains fully developed ...

Stunning of the myocardium: An update [PDF]
Cardiovascular Drugs and Therapy, 1991 When severely ischemic myocardium is reperfused, prolonged myocardial dysfunction--a phenomenon named myocardial stunning--frequently occurs. Stunning also occurs in a variety of other situations. These include myocardium located adjacent to infarcted tissue, transient increase in myocardial O2 demands in the presence of incomplete coronary obstruction,

CALCIFICATION OF THE MYOCARDIUM
Annals of Internal Medicine, 1947Excerpt In 1924 Scholz1assembled from the literature 30 cases of calcification of the myocardium. He classified 14 as due to myocarditis.

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.

Stunned Myocardium and Hibernating Myocardium: Pathophysiology
2001The 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 ...

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.
