Myocardial Infarct Quantification
Radionuclide techniques for sizing acute myocardial infarction have been hampered by the intrinsic limitations of the scintillation camera. Emission computed tomography can overcome these limitations. Single photon emission computed tomograms of the distribution of technetium-99m pyrophosphate in acute anterior and posterior infarcts were obtained in 16 dogs after death. Tomograms were also obt...
متن کاملEnzymatic profile of myocardial infarct.
T he causal relationship between the rise in activity of certain enzymes in the serum and the occurrence of damage to the myocardium has been established without question. Experiments and histochemical investigations have shown that infarcted heart muscle is rapidly depleted of various enzymes, and that these enzymes appear in an active form in the blood that drains from the infarcted myocardiu...
متن کاملRelationship Between Myocardial Infarct Size
We compared myocardial infarct size produced by permanent occlusion of the middle left anterior descending (LAD) or circumflex (LCx) coronary artery in the anesthetized dog. The dogs were killed 3-10 days later, and the occluded coronary bed was visualized by postmortem arteriography. The outlines of the infarct and occluded bed were marked on tracings of weighed left ventricular (LV) rings and...
متن کاملMyocardial Infarct Size in Humans
Background. The influence of coronary collateral vessels on infarct size in humans remains controversial, partly because no previous study has examined the impact of collaterals present at the onset of acute myocardial infarction on infarct size. Methods and Results. The present study used the data base of the Thrombolysis in Myocardial Infarction (TIMI) Phase I trial to correlate the presence ...
متن کاملMyocardial Infarct Size and Location
Recent infarcts were compared with the anatomic boundaries of the involved vascular bed in human hearts to determine the amount and location of necrosis in relation to the myocardium at risk. The coronary arteries were injected with BaSo4 in 18 human hearts with 3-16-day-old infarcts. Thin (3-4-mm) slices were cut at 10-15-mm intervals, photographed, x-rayed and used for histologic analysis. In...
