Extent of Myocardial Infarction in Awake Dogs
نویسنده
چکیده
This study was designed to examine the relationship between epicardial ST change (EpST) and regional myocardial blood flow (RMBF) following coronary occlusion and extent of myocardial infarction (MI) in awake dogs. Fifteen min and two hr after coronary occlusion simultaneous measurements of EpST and RMBF were made. Six days later histologic MI and RMBF were determined in transmural myocardial samples from each electrode site. Greatest ST elevation occurred at sites of greatest ischemia and MI.

Influence of dobutamine on regional myocardial blood flow and ventricular performance during acute and chronic myocardial ischemia in dogs.
The data from this study document that dobutamine is a powerful inotropic agent in anesthetized dogs with acute myocardial ischemia and in awake, unsedated ones with chronic myocardial infarction. Dobutamine significantly increases heart rate at relatively small doses in anesthetized dogs with acute myocardial ischemia but considerably larger amounts of dobutamine are required to significantly ...
متن کاملThe influence of hypertonic mannitol on regional myocardial blood flow during acute and chronic myocardial ischemia in anesthetized and awake intact dogs.
The influence of hypertonic mannitol on regional myocardial blood flow and ventricular performance was studied during acute myocardial ischemia in awake, unsedated and in anesthesized dogs and after myocardial infarction in awake unsedated dogs. Regional myocardial blood flow was measured with radioactive microspheres. Generalized increases in regional myocardial blood flow occurred after manni...
متن کاملInfarct Size in Awake Dogs With Acute Myocardial Infarction
Background. Short-term cholesterol feeding has been shown to affect vasomotor tone and increase infarct size in anesthetized rabbits. The purpose of the study was to determine whether acute hypercholesterolemia reduced collateral flow to ischemic myocardium and increased infarct size in the awake dog. Methods and Results. Acute myocardial infarction was produced in awake dogs by a 4-hour left a...
متن کاملReperfusion alters the relation between blood flow and the remaining myocardial infarction.
This study evaluated whether or not reperfusion of ischemic myocardium 2 hours after occlusion alters the basic relation between myocardial blood flow and infarction occurring during permanent occlusion. Awake mongrel dogs chronically instrumented with proximal circumflex coronary occluders were subjected to permanent occlusion (group A, n = 10) or occlusion followed by reperfusion 2 hours late...
متن کاملMyocardial Infarction in a Rhesus Monkey
Myocardial necrosis can be result from a number of causes including nutritional deficiencies, chemical and plant toxins, ischemia and metabolic disorder. The outcome of myocardial necrosis varies depending on the extent of the damage (Donald 2001, Jubb 1993, Radostits 1994, Vanvaleet 1986). Myocardial infarction without demonstrable of atherosclerosis were reported in a rhesus macaque (Gonder 1...
