Contrast-enhanced Cardiovascular Magnetic Resonance Clinical Study Of The Differentiation Between Ischemic Cardiomyopathy And Primary Dilated Cardiomyopathy

AimTo evaluate the diagnostic role of contrast-enhanced cardiovascular magnetic resonance(CE-CMR) in differentiating dilated cardiomyopathy from ischemic cardiomyopathy.MethodsEnrolled 102 patients with dilated left ventricular and decreased systolic function who went to our hospital for CE-CMR and Coronary angiography from January,2008 to August,2012. Patients were divided into 2 groups:28 dilated cardiomyopathy patients and 74 ischemic cardiomyopathy patients, we observed the position, extent and range of delayed enhancement in left ventricular.ResultsIn the dilated cardiomyopathy group,8 patients showed delayed enhancement, included 1 subendocardial,3 mid-wall,3 scattered and 1 patchy delayed enhancement. In the ischemic cardiopathy group,66 patients showed delayed enhancement, included 58 transmural and 7 subendocardial delayed enhancement. (respectively; all p< 0.005).ConclusionCMR is an effectve methods in differentiating dilated cardiomyopathy from ischemic cardiomyopathy, combined with coronary angiograpy can provide important considerable value in differential diagnosis.
