Key result
Cardiac magnetic resonance tissue characterization and volume assessment improve the prognostic stratification of adverse cardiac events and ventricular arrhythmias in dilated cardiomyopathies beyond 2D-echocardiography LVEF.
Why the study?
Literature supporting the prognostic value of cardiac magnetic resonance (CMR) imaging in cardiology has been relatively scarce, though recent reports examining its role in prognostic assessment of adverse cardiac events in dilated cardiomyopathies have raised clinical and financial management issues.

May support CMR for refined risk stratification in dilated cardiomyopathies; hypothesis-generating and leaves open prospective validation.
Cardiac Magnetic Resonance (CMR) has a relevant role in the comprehensive assessment of cardiac function, morphology and myocardial characterization.The high spatial resolution offers precise evaluation of cardiac volumes without geometric assumptions and myocardial characterization of edema, fat infiltration and fibrosis offers a sort of “in-vivo” virtual pathology. For these reasons the role of CMR imaging in the diagnostic workup of cardiomyopathies has gained increasing relevance, improving the assessment of many relevant issues as the etiology of sudden cardiac arrest [1], the evidence and extension of myocardial fibrosis in ischemic and non-ischemic cardiomyopathies [2,3], the evidence of fat and fibrotic infiltration in arrhytmogenic cardiomyopathies [4,5]. The relatively scarce literature supporting a prognostic value of CMR imaging data is due to the short history of MR imaging in cardiology. Recently, an increasing number of reports is supporting the role of CMR data in the prognostic assessment of adverse cardiac events in dilated cardiomyopathies, raising relevant clinical and financial issues in the management of patients.

Alberto Roghi (2018) conducted an editorial in Dilated Cardiomyopathy. Cardiac Magnetic Resonance (CMR) with late gadolinium enhancement (LGE) vs. 2D-echocardiography LVEF was evaluated on Prognostic assessment of adverse cardiac events and ventricular arrhythmias. Cardiac magnetic resonance tissue characterization and volume assessment improve the prognostic stratification of adverse cardiac events and ventricular arrhythmias in dilated cardiomyopathies beyond 2D-echocardiography LVEF.
