Table 1 Contrast Induced by the Two Agents in Acute versus Subacute Infarcts

From: Differentiation of acute and four-week old myocardial infarct with Gd(ABE-DTTA)-enhanced CMR

  Gd(ABE-DTTA) Gd(DTPA)
Parameter Acute infarct Subacute infarct Acute infarct Subacute infarct
SIE (%)* 366 ± 166 24 ± 59 431 ± 124 400 ± 124
P value† vs. normal myocardium P < 0.05 NS P < 0.05 P < 0.05
P value vs. Gd(ABE-DTTA)subacute P < 0.05   P < 0.05 P < 0.05
P value vs. Gd(ABE-DTTA)acute    NS NS
P value vs. Gd(DTPA)acute     NS
  1. *Mean ± SD (n = 6) signal intensity enhancement (in percent values) by Gd(ABE-DTTA) or Gd(DTPA) in the territory of acute or subacute occlusions
  2. †P values pertain to pairwise comparisons by the Holm-Sidak method of the different subgroups.
