Infarct tissue characteristics of patients with versus without early revascularization for acute myocardial infarction: a contrast enhancement cardiovascular magnetic resonance imaging study

Histopathological studies suggested that early revascularization for acute myocardial infarction (MI) limits size, transmural extent, and homogeneity of myocardial necrosis. However, the long-term effect of early revascularization on infarct tissue characteristics is greatly unknown. Cardiovascular magnetic resonance (CMR) imaging with contrast enhancement (CE) allows non-invasive examination of infarct tissue characteristics and left ventricular (LV) dimensions and function in one examination.
