Recognition of neurogenic myocardial injury / 中国实用内科杂志

Transient,reversible myocardium injury can occur in patients with brain injury.Several pathophysiological mechanisms are involved in the development of such neurogenic myocardium injury.Excess catecholamine release plays a major role during myocardial injury.The clinical features include abnormal electrocardiographic,echocardiographic features and elevated biomarkers.In some patients stunned myocardium can be observed which may lead to hemodynamic instability or even cardiogenic shock.Inotropic agents and mechanical support are useful in improving cardiac function.β-adrenergic blockade is likely to attenuate the catecholamine toxicity but its use remains controversial.
