title: [Neurogenic stunned myocardium].
abstract: The existence of stunned myocardium and reversible myocardial dysfunction is widely described and accepted in patients suffering ischemic heart disease. However, it cannot be exclusive to coronary disease. Classically, the appearance of electrocardiographic changes in the critical neurological disease has been described. However, at present, it seems to be observed that some of these patients with critical neurological disease could have variable grades of myocardial dysfunction, which is generally reversible in the surviving patients. This myocardial dysfunction, which could affect critically ill neurological patients, has traits similar to stunned myocardium generated in coronary patients since: a) it is generally associated to electrocardiographic changes, b) it can be accompanied by segmental contractility disorders and even c) it may be accompanied by a certain increase of cardiac biomarkers. Although its etiopathogeny is unknown, it could be related with the severity of the primary neurological disease. Its prophylaxis and prognosis are also unknown. It could be related with neurogenic edema, with hemodynamic instability, and could also play a very important role in brain death and in organ donation.
