Cardiac Magnetic Resonance (CMR) provides a comprehensive non-invasive characterization of acute myocardial infarction (MI).
to test whether a single CMR study may improve the prognostic stratification of MI patients.
29 patients were studied on day 3 ± 1 after a first MI, between June 2006 and April 2007. CMR included SSFP and T2 STIR sequences, first pass perfusion, Early (EGE: 1 to 2 minutes) and Late (LGE: 10 to 15 minutes) Gadolinium Enhancement. Subsequent clinical management was not affected from CMR results, and patients underwent the usual clinical and echocardiographic follow-up. In 2009 we tested the occurrence of the end-point of cardiac death or left ventricular (LV) remodelling (EDVi > 90 ml/m2 or LVEF < 50% at echocardiographic follow-up) in the studied population.
Positive Predictive Value %
Negative Predictive Value %
(>20% LV mass)
Area at risk (>40% LV mass)
T2-STIR images allow a long-term prognostic stratification of unrivalled accuracy during the acute phase of MI. The use of gadolinium do not significantly improve the prognostic accuracy of CMR.
