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
Body donation as medical schools, which teach anatomy using donated bodies. Under the Human Tissue Act, written consent must be given prior to death; consent cannot be given by anyone else after death. The Human Tissue Authority provides information to donors about where they can donate and answers many prevalent questions related to tissue donation on their website. The Human Tissue Authority provides the links to each establishment’s information, but each establishment has its own guidelines for body donation. The HTA also provides the tools to find donation sites local to the person wishing to donate their body, or tissues. Although most
