High-risk patients with mild-moderate left ventricular dysfunction after a previous myocardial infarction. A long-term prognostic data by cardiac magnetic resonance

After adjustment for age, an extent of LGE > 11.3%, a dilated LV (male > 112 ml/m2; female > 92 ml/m2) and a WMSI > 1.59 were associated with adverse cardiac events in patients with MM-LV-D. In patients with MM-LV-D, when each of these 3 factors was observed, the prognosis was worse respect to those with 1-2 factors and no factor (p = 0.035 and p = 0.004, respectively). Prognosis was similar (p = 0.61) between MM-LV-D patients with all 3 factors and those with S-LV-dysfunction. CONCLUSIONS. A multiparametric CMR approach, which includes LGE, dilated LV and WMSI, permits to identify post MI patients with MM-LV-D with a risk of cardiac events similar to those with S-LV-D. Further multicenter studies are needed to confirm our data.
