Background Recent studies indicate that magnetic resonance imaging(MRI) after the administration of contrast material can be usedto distinguish between reversible and irreversible myocardialischemic injury regardless of the extent of wall motion or theage of the infarct. We hypothesized that the results of contrast-enhancedMRI can be used to predict whether regions of abnormal ventricularcontraction will improve after revascularization in patientswith coronary artery disease.
Methods Gadolinium-enhanced MRI was performed in 50 patientswith ventricular dysfunction before they underwent surgicalor percutaneous revascularization. The transmural extent ofhyperenhanced regions was postulated to represent the transmuralextent of nonviable myocardium. The extent of regional contractilityat the same locations was determined by cine MRI before andafter revascularization in 41 patients.
Results Contrast-enhanced MRI showed hyperenhancement of myocardialtissue in 40 of 50 patients before revascularization. In allpatients with hyperenhancement the difference in image intensitybetween hyperenhanced regions and regions without hyperenhancementwas more than 6 SD. Before revascularization, 804 of the 2093myocardial segments analyzed (38 percent) had abnormal contractility,and 694 segments (33 percent) had some areas of hyperenhancement.In an analysis of all 804 dysfunctional segments, the likelihoodof improvement in regional contractility after revascularizationdecreased progressively as the transmural extent of hyperenhancementbefore revascularization increased (P<0.001). For instance,contractility increased in 256 of 329 segments (78 percent)with no hyperenhancement before revascularization, but in only1 of 58 segments with hyperenhancement of more than 75 percentof tissue. The percentage of the left ventricle that was bothdysfunctional and not hyperenhanced before revascularizationwas strongly related to the degree of improvement in the globalmean wall-motion score (P<0.001) and the ejection fraction(P<0.001) after revascularization.
Conclusions Reversible myocardial dysfunction can be identifiedby contrast-enhanced MRI before coronary revascularization.
