Myocardial stunning after cerebral infarction

International Journal of Cardiology, 1997
Myocardial stunning has not been described in patients with cerebrovascular accidents. We present a patient in whom inferior wall hypokinesis, ST-segment elevations and Q waves developed after acute right hemisphere ischemic stroke. Total recovery ensued within 5 days. Coronary vasospasm induced by stroke-related sympathetic surge might be the cause of

Energy metabolism in myocardial stunning

Journal of Molecular and Cellular Cardiology, 1992
We investigated the effect of reversible ischemia, leading to persistent contractile dysfunction (stunning), on myocardial energy metabolism. The balance of energy metabolism is expressed by the phosphorylation state of cytosolic nucleotides. This variable cannot be measured directly because of nucleotide compartmentation, but in the isolated heart it ...

Therapy of myocardial stunning

Basic Research in Cardiology, 1997
Since in the clinical setting stunning may coexist with persistently ischemic and infarcting myocardium, the ben fit el therapeutic interventions on the stunned myocardium must be weighed against potential deleterious effects on the ischemic myocardium.

Therapeutic Hyperoxia Diminishes Myocardial Stunning

Journal of Cardiac Surgery, 1994
We used a model of isolated coronary perfusion to answer the question: Does high PO2 during low flow myocardial ischemia diminish postischemic myocardial contractile dysfunction? In 12 anesthetized, open chest swine, the left anterior descending (LAD) coronary artery was cannulated and perfused via an extracorporeal circuit. Normoxic arterial blood was

Mitochondrial function in myocardial stunning

Journal of Molecular and Cellular Cardiology, 1991
Mitochondrial respiration parameters were studied in mitochondria isolated from normal, ischemic and post-ischemic rabbit hearts. Mitochondrial function was related to tissue content of high energy phosphates (HEP) and cardiac function in the isolated working rabbit heart preparation.

Models of Myocardial Stunning

Journal of Cardiac Surgery, 1993
The use of animal models is a valuable approach to the elucidation of the pathophysiology of myocardial stunning. Coronary occlusion followed by reperfusion produces stunning experimentally, mimicking a myocardial infarction followed by thrombolysis, angioplasty, or coronary bypass.

Myocardial Stunning Following Respiratory Arrest

Chest, 1995
Myocardial stunning is defined as a prolonged myocardial dysfunction with gradual return of contractile activity after a brief episode of severe ischemia. Usually it is seen in patients with myocardial infarction following treatment with thrombolytic agents, in patients with angina, and in patients recovering from cardiopulmonary bypass surgery.

Myocardial Stunning after Electroconvulsive Therapy

Annals of Internal Medicine, 1992
Excerpt Myocardial stunning (1, 2), a prolonged but reversible myocardial contractile dysfunction, has not been reported after electroconvulsive therapy (ECT).

Mechanisms Underlying Myocardial Stunning

Journal of Cardiac Surgery, 1993
The effect of myocardial stunning on mitochondrial function was examined in rabbit hearts. After global normothermic ischemia followed by reperfusion, we previously found that mitochondrial high energy phosphate content was not significantly diminished.

Myocardial Stunning: An Overview

Journal of Cardiac Surgery, 1993
Over the past two decades, we have challenged the belief that transient ischemia is benign with little functional sequelae following resolution of ischemia. The phenomenon of prolonged postischemic contractile dysfunction, or of myocardial stunning, has been developed and is under investigation using multiple experimental and clinical models ...
