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...
متن کاملNeurogenic Stunned Myocardium
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 کاملStunned myocardium after hip arthroplasty.
We report a case of ST-segment elevation occurring in all leads of the ECG during hip arthroplasty. It is thought that this resulted from a stunned myocardium because wall motion abnormalities were reversible, there was no evidence of fixed or vasospastic coronary occlusion and there was only a slight increase in serial cardiac enzymes. Treatment with nicorandil improved the patient's cardiac f...
متن کاملCollagen loss in the stunned myocardium.
BACKGROUND This study was performed to biochemically assess and quantify the previously observed ultrastructural alterations in the collagen matrix of stunned myocardium. METHODS AND RESULTS The stunned myocardium was produced in 13 mongrel dogs by a series of 12 coronary artery occlusions of 5 minutes followed by 10-minute reperfusion periods, with a final reperfusion period of 90 minutes. R...
