[Computerized two-dimensional echocardiography in acute myocardial infarction. Possibility of determining the size of...

Myocardial asynergic area was estimated, using a new special mathematical model based on computerized assessment of echocardiographic images, in 42 patients with first acute transmural myocardial infarction. The results were compared with those of other standard methods used for the estimation of the size of damage, and with morphologic findings in 7 fatal cases. The latter comparison demonstrated that the special estimate of asynergic area, unlike the planimetric method, used earlier, showed a high correspondence to the actual size of damage. The comparison of echocardiographic data to those obtained by other techniques showed a significant correlation with the results of serial MB CFK assays and myocardial 201Tl scintigraphy.
