Plasma MIF levels of patients in the diabetes and nondiabetes STEMI groups were negatively correlated with LVEF within 72 h of admission (r = −0.336 and r = −0.365, respectively, both P < 0.01, Figure 2(a)) but were positively correlated with LVDD (r = 0.198, r = 0.301, all P < 0.05). This evidence concerns the gene MIF and diabetes mellitus.
