Table 4 Transmurality and SWT

From: Comparison of wall thickening and ejection fraction by cardiovascular magnetic resonance and echocardiography in acute myocardial infarction

Transmurality Number of segments Mean SWT ± SE Statistical difference to group 2 (< 50%) Statistical difference to group 3 (> 50%)
group 1: 0 448 63.6% ± 20.4% n.s. p < 0.001
group 2: < 50% 59 50.44% ± 48.7% x n.s.
group 3: > 50% 325 50.08% ± 20.0% n.s. x
  1. In order to detect differences between the transmural extent of the infarct and changes of SWT (systolic wall thickening), we made three groups according to their transmurality (first had no transmurality, second had less than 50%, and the third had more than 50% transmurality). In the acute state of myocardial infarction we detected a highly significant difference in SWT between the first group with no scar and group 3 (p < 0.001). Within the groups there could not be detected any difference regarding SWT and transmurality. There could not be detected any difference between group 1 and group 2. n.s. = not significant, SE = standard error. ANOVA with Bonferroni post-hoc testing was used for statistical analysis.
