Cardiac toxicity was mediated more by catecholamines released directly into the heart via neural connection than by those reaching the heart via the bloodstream. The mechanisms underlying the association between this generalized autonomic storm secondary to a life-threatening stress and myocardial toxicity are widely discussed. Takotsubo cardiomyopathy has been reported all over the world and has been acknowledged by the American Heart Association as a form of reversible cardiomyopathy. Four Mayo Clinic diagnostic criteria are required for the diagnosis of Takotsubo cardiomyopathy 1 transient left ventricular wall motion abnormalities involving the apical and or midventricular myocardial segments with wall motion abnormalities extending beyond a single epicardial coronary artery distribution 2 absence of obstructive epicardial coronary artery disease that could be responsible for the observed wall motion abnormality 3 ECG abnormalities such as transient ST-segment elevation and or diffuse T wave inversion associated with a slight troponin elevation and 4 the lack of proven pheochromocytoma and myocarditis. ECG changes and LV dysfunction occur frequently following subarachnoid hemorrhage and ischemic stroke. This entity referred as neurocardiogenic stunning was called neurogenic stress-related cardiomyopathy. Stress-related cardiomyopathy has been reported in patients with
