A Review of Neurogenic Stunned Myocardium
نویسندگان
چکیده
Neurologic stunned myocardium (NSM) is a phenomenon where neurologic events give rise to cardiac abnormalities. Neurologic events like stroke and seizures cause sympathetic storm and autonomic dysregulation that result in myocardial injury. The clinical presentation can involve troponin elevation, left ventricular dysfunction, and ECG changes. These findings are similar to Takotsubo cardiomyopathy and acute coronary syndrome. It is difficult to distinguish NSM from acute coronary syndrome based on clinical presentation alone. Because of this difficulty, a patient with NSM who is at high risk for coronary heart disease may undergo cardiac catheterization to rule out coronary artery disease. The objective of this review of literature is to enhance physician's awareness of NSM and its features to help tailor management according to the patient's clinical profile.

Neurogenic Stunned Myocardium Associated with Acute Spinal Cord Infarction: A Case Report
Introduction. Neurogenic stunned myocardium (NSM) is a reversible cardiomyopathy resulting in transient left ventricular apical ballooning presumed to result from catecholamine surge occurring under physiologic stress. Acute spinal cord ischemia is a rare ischemic vascular lesion. We report a case of neurogenic stunned myocardium occurring in the setting of acute spinal cord infarction. Methods...
متن کاملThe role of nuclear cardiac imaging in redefining neurogenic stunned myocardium in subarachnoid hemorrhage: a deeper look into the heart
Subarachnoid hemorrhage may be complicated by neurogenic stunned myocardium, a catecholamine-induced transient cardiomyopathy that displays a wide clinical spectrum of cardiac abnormalities, including electrocardiographic changes, arrhythmias, myocardial necrosis, and left ventricular systolic and diastolic dysfunction. However, less is known about the cardiac metabolic consequences of acute su...
متن کاملManagement of patients with stunned myocardium associated with subarachnoid hemorrhage.
Cardiac complications are well known after aneurysmal subarachnoid hemorrhage. Electrocardiographic changes occur in 50% to 100% of such cases. Arrhythmias, left ventricular dysfunction, and frank myocardial infarction are infrequently observed. Myocardial infarction must be differentiated from neurogenic stunned myocardium, which is a reversible condition. From 1996 to 2001, 105 patients with ...
متن کاملNeurogenic stunned myocardium with ventriculoperitoneal shunt malfunction.
The syndrome of left ventricular dysfunction in patients without obstructive coronary artery disease following central nervous system injury is termed neurogenic stunned myocardium (NSM). It has been described most commonly in association with aneurysmal subarachnoid hemorrhage. Nonspecific electrocardiogram (ECG) abnormalities, elevated troponin I levels, and reversible regional-wall motion ab...
متن کاملPathology of Takotsubo (Ampulla) Cardiomyopathy
Takotsubo (ampulla) cardiomyopathy is characterized by slight to moderate elevation of cardiac enzymes. It is reasonable to think that the elevated levels are evidence of myocardial damage (cardiac-specific enzymes are released from the cytoplasm of damaged cardiac myocytes into extracellular fluid). Thus, it is problematic to consider takotsubo cardiomyopathy as (neurogenic) stunned myocardium...

BACKGROUND Neurogenic pulmonary edema (NPE) is a clinical syndrome usually defined as an acute pulmonary edema occurring shortly after a central neurologic insult. NPE was identified 100 years ago, but it is still underappreciated in the clinical setup. NPE usually appears within minutes to hours after the injury. It has a high mortality rate if not recognized early and treated appropriately. S...
