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

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

	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

*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
†P values pertain to pairwise comparisons by the Holm-Sidak method of the different subgroups.
