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 کاملComparison of methods for DE-CMR infarct size quantification - reproducibility among three core labs
Background Infarct size measurements with delayed-enhancement cardiovascular magnetic resonance (DE-CMR) are being used as surrogate endpoints in acute myocardial infarction (AMI) trials comparing therapeutic strategies. Semiautomated techniques using signal intensity thresholding are thought to be more reproducible than manual planimetry to define AMI borders. For both methods, endo-/ epicardi...
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 کاملDeterminant of Infarct Size After Direct Angioplast
Background. In acute myocardial infarction, residual flow to the infarct zone either through antegrade flow in the infarct-related coronary artery or collateral flow from the non-infarct-related arteries is often present before reperfusion therapy. The purpose of this study was to assess the influence of antegrade flow in the infarct-related artery and/or collateral flow to the infarct zone bef...
متن کاملRapid estimation of myocardial infarct size.
See article by de Groot et al. [9] (pages 315 –324) in this limitation of enzymatic infarct size [7]. Earlier, we demonissue. strated that thrombolytic therapy had no influence on the relation between infarct size estimated with aHBDH and Although the use of biochemical markers of acute left ventricular performance, indicating that coronary remyocardial infarction started in 1954 [1], their val...
