Abstract

This research work is based on the analysis of the results of 15 patients with postischemic scarring of the LV myocardium. The Pearson correlation coefficient had a high value. The null hypothesis was put forward that the mathematical expectation of the difference between the results of the two measurements is zero. The student’s T-test did not refute this hypothesis. At the final stage, the samples were analyzed using the Bland-Altman method, which resulted in the conclusion that both methods are consistent with each other, and a high spread may be due to the fact that one of the methods is not accurate enough. Since the new method does not have the main drawback of the currently widely used segmental method (a step of 25 %), it was concluded that it can provide a more accurate estimate of the proportion of the affected area of the LV myocardium.
