"Hibernating" myocardium: not only a matter of semantics.
Matter of Semantics To the Editor: The recent article by Kalra et al1 reiterates the use of the term “hibernating myocardium,” which was introduced by Diamond et al in 19782 to indicate a state of chronically ischemic noninfarcted myocardium. The term is incorrect and should be abandoned. In Dorland’s Illustrated Medical Dictionary, hibernation is defined as “the dormant state in which certain ...
متن کاملHibernating myocardium.
Decreased myocardial contraction occurs as a consequence of a reduction in blood flow. The concept of hibernation implies a downregulation of contractile function as an adaptation to a reduction in myocardial blood flow that serves to maintain myocardial integrity and viability during persistent ischemia. Unequivocal evidence for this concept exists in scenarios of myocardial ischemia that last...
متن کاملUkraine: not only a matter of geopolitics.
Ukraine is once again at a political crossroads. Like many of the world’s troubled nations, its presentday borders refl ect historical events that paid little attention to the national identities of those involved, such as the westward expansion after World War 2 into what had been Polish territory, and Nikita Khrushchev’s unexpected 1954 gift from Russia to Ukraine of Crimea. Just like Russia ...
متن کاملThe Sleeping Heart : Hibernating Myocardium
Classical teaching about myocardial ischemia is now being challenged by exciting new concepts that have been evolving over the past two decades. It is now recognized that prolonged myocardial ischemia does not inevitably lead to irreversible necrosis of myocardial tissue. Similarly, segment dysfunction in the ventricle does not necessarily imply that the myocardium in that area has undergone in...
متن کاملHibernating myocardium: new answers, still more questions!
In the early 1980s, Rahimtoola 1 reviewed the results of coronary bypass surgery trials and identified patients with coronary artery disease and chronic left ventricular dysfunction that improved upon revascularization. He proposed the concept of hibernating myocardium as “prolonged ischemia. . . in which myocardial metabolism and ventricular function are reduced to match the reduced blood supp...
