Myocardial contraction band necrosis in stranded cetaceans

Journal of Comparative Pathology, 1998
The term contraction band necrosis describes focal hypercontraction and lysis of small groups of myocardial cells. Contraction band necrosis of the myocardium was identified in 100% of 52 whales and dolphins (cetaceans) stranded along the western coast of the Gulf of Mexico between April 1991 and November 1996.

THE INHIBITORY EFFECT OF ACETOACETATE ON MYOCARDIAL CONTRACTION

The Lancet, 1962
Williamson and Krebs 1 and Hall 2 have recently reported that acetoacetate, when added to the perfusion medium of an isolated heart in concentrations as high as or higher than in cases of mild ketosis, is oxidised in preference to glucose. These workers, and also Ottaway and Sarkar,3 have shown that lactate accumulated in the perfusion fluid ...

Physiology of Myocardial Contraction

2002
The principal function of the heart is to propel oxygenated blood to the peripheral tissues to meet their metabolic demands. The systemic arterial and venous systems provide the conduits. The interaction of the left ventricle (LV) with the arterial and venous systems is therefore integral to the satisfactory performance of this vital function.

[Reversible dysfunction of myocardial contraction].

Vnitrni lekarstvi, 1999
It has been known for more than 20 years that in some patients after revascularization partial or complete improvement of previous left ventricular dysfunction occurs. The condition for this improvement is viable myocardium, i.e. contractile reserve. Chronic reversible contractile dysfunction, also called hibernating myocardium heart muscle is along ...

[Cardiac myosins and myocardial contraction].

Giornale italiano di cardiologia, 1987
The contractile properties of cardiac muscle cells are determined by the molecular composition of the contractile apparatus and in particular by the structure of myosin. Three isoforms of myosin heavy chains have been recently identified in the mammalian heart: alpha and beta myosin heavy chains, present in atrial and ventricular myocardium, and nodal ...
