Clinical Measurement of Myocardial Infarct Size
A modified method for the measurement of total creatine phosphokinase release from venous blood samples taken four-hourly after myocardial infarction has been used in 43 patients admitted to a Coronary Care Unit. The fractional decay rate (KD) of enzyme activity has been measured by a standardized method in each patient, and accuracy of the calculation of total enzyme release has been improved ...
متن کاملMyocardial infarct size measurement in the mouse chronic infarction model: comparison of area- and length-based approaches.
Efficacy of potential treatments for myocardial infarction (MI) is commonly assessed by histological measurement of infarct size in rodent models. In experiments involving an acute MI setting, measurement of the infarcted area in tissue sections of the left ventricle is a standard approach to determine infarct size. This approach has also been used in the chronic infarct setting to measure infa...
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 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 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...
