Stunned Myocardium of Dog
Recent studies have shown that myocardial oxygen consumption does not proportionally decrease with the deterioration of contractile function in stunned myocardium. To investigate this disproportion, we studied the end-systolic pressure-volume relation and the relation between oxygen consumption per beat (Vo2) and systolic pressure-volume area (PVA, a measure of total mechanical energy) in stunn...

Background. The main objective of the present study was to determine the role of adenosine in the development of myocardial stunning following multiple, brief periods of coronary artery occlusion as well as the subtype of adenosine receptor (A1 or A2) involved. A second objective was to determine if there was an interaction between the adenosine A1 receptor and the ATP-dependent K channel (KATP...

A74-year-old woman was admitted for evaluation of chest pain. She had fallen and hit her head 4 days before her admission and had lost consciousness. Her chest pain had begun immediately after this event. An ECG on admission revealed abnormal Q waves and ST-segment elevation (Figure 1A). Her plasma creatine phosphokinase level was significantly elevated (386 IU/L), with an increase in MB isozym...
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 کاملA Review of Neurogenic Stunned Myocardium
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 cardiomyopa...
