Regional Heterogeneity of Human Myocardial Infarcts Demonstrated by Contrast-Enhanced MRI
Why the study?
Does contrast-enhanced MRI demonstrate regional heterogeneity and correlate with scintigraphic defects in patients with acute myocardial infarction?
Population

Implication
MRI may differentiate reperfused from non-reperfused infarcts; leaves open prospective validation versus scintigraphy before clinical use.

Outcome
Characterization of infarct patterns and correlation of MRI hyperenhanced segment with fixed scintigraphic defectsurrogate
Contrast-enhanced MRI can characterize the regional heterogeneity of myocardial infarcts, differentiating between large non-reperfused and reperfused infarcts.
