011 Diffusion weighted magnetic resonance imaging and LVEF recovery after acute myocardial infarction

Background Diffusion weighted magnetic resonance imaging (DWI) is used to identify tissue injury area in patients admitted for stroke. Limited study has been performed to evaluate its clinical interest in patients with acute ST elevation myocardial infarction (STEMI). Methods The study included 17 patients (14 men, 55 ± 14years, 12 anterior) with a recent STEMI ( Results Large area of hypersignal correlated with impaired baseline LVEF whatever b value (r value range between 0.58 and 0.60, p Conclusion In patients with acute MI, hypersignal area from diffusion weighted magnetic resonance imaging with b = 50 sec/mm2 seems to provide an accurate assessment of myocardial injury and may be used to predict LVEF recovery.
