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
