should also maintain normal perfusion, detected via Positron Emission Tomography, echocardiography with contrast, and/or thallium scintigraphy in order for a diagnosis of myocardial stunning to be considered. However, there are many practical challenges to diagnosing myocardial stunning using these methods. Accurate detection of regional myocardial blood flow and contraction function abnormalities must be detected at levels of high sensitivity. The diagnosis of myocardial stunning must also be differentiated from other conditions such as hibernating myocardium and persistent (silent) subendocardial ischemia, which can also co-exist with superimposed stunning. Management Treatment considerations for myocardial stunning should be determined based on the clinical judgment of the cardiologist or physician, the degree of LV impairment and symptoms, and the wishes of the person. Some evidence supports the use of inotropic drugs in the case of severe myocardial dysfunction. Results from canine experimental trials investigating the oxygen free-radical hypothesis for myocardial stunning have shown a reduction in free radical generation and improvement in myocardial function following anti-oxidant infusion.
