(A) There was a significant positive relationship between the postinfarction change in stressed blood volume, , and the difference in peak circumferential stretch, . (B) There was a significant positive relationship between the postinfarction change in and the difference in peak radial stretch, . (C) There was a significant negative relationship between the postinfarction change in and the postinfarction difference in peak . In all cases, linear regression passed the test for homoscedasticity and the two-tailed Pearson correlation coefficients were considered significant if p < 0.05.
