The quantification of infarct size.
We sought to summarize the published evidence regarding the measurement of infarct size by serum markers, technetium-99m sestamibi single-photon emission computed tomography (SPECT) myocardial perfusion imaging, and magnetic resonance imaging. The measurement of infarct size is an attractive surrogate end point for the early assessment of new therapies for acute myocardial infarction. For each ...
متن کاملVectorcardiographic quantification of infarct size in baboons.
A vectorcardiographic method has been developed for determining the absolute size of myocardial infarcts in baboons resulting from coronary artery ligation. Spatial area (mvolt . msec) and voltage (mvolt) difference-vectors were obtained for 8 animals by measuring the voltage loss and temporal deviation from pre- to post-ligation McFee scalar leads. The difference vectors were then correlated w...
متن کاملQuantification of cerebral infarct size by creatine kinase BB isoenzyme.
Creatine Kinase BB isoenzyme (CKBB) has been shown to rise in the serum and CSF following acute cerebral injury. To test the hypothesis that brain infarct size could be estimated from the appearance and disappearance of CKBB in the serum and CSF, strokes of varying size were produced in twelve mongrel dogs by silastic emboli. The rate of disappearance, Kd of CKBB (-.00732 +/- 0.001 min-1 mean +...
متن کاملMyocardial 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 کاملModification of infarct size.
To the Editor: The article by Maroko and his co-workers entitled "Factors Influencing Infarct Size Following Experimental Coronary Artery Occlusions" (Circulation 43:67, 1971) is indeed a very interesting one and an enthusiastic approach to the problem of modification of the size of an infarct. However, there are several points with regard to the methods that seem to need some clarification. Th...
