Hibernating myocardium Hibernating myocardium In cardiology, hibernating myocardium is a state when some segments of the myocardium exhibit abnormalities of contractile function. These abnormalities can be visualised with echocardiography, cardiac magnetic resonance imaging (CMR), nuclear medicine (PET) or ventriculography. Echocardiography: A wall motion abnormality at rest which improves during a low-dose dobutamine stress test is classified as "hibernating myocardium". Low dose dobutamine stimulates contractile function and thus helps to predict functional recovery after revascularization. Cardiac magnetic resonance: The most frequently used MR contrast agents based on Gd-chelates accumulate in the extracellular space which is increased in scarred myocardium. This leads to a
Tissue bank companies under the pretense that they had already been tested for infectious diseases. Specifically, Johnson & Johnson was purchasing body parts from the director of UCLA’s willed body program at a steep price. The representative from Johnson & Johnson claimed that he had no reason to suspect that the body parts were distributed to him illegally. Tissue bank A tissue bank is an establishment that collects and recovers human cadaver tissue for the purposes of medical research, education, and allograft transplantation. A tissue bank may also refer to a location where biomedical tissue is stored under cryogenic conditions, and is
