After adjusting for clinical characteristics, higher categories of DM (no‐DM, pre‐DM, and DM) were associated with worse LV systolic function (lower LVEF [P=0.002] and GLS [P<0.001]), worse LV diastolic function (higher E/e'‐ratio [P<0.001]), and higher concentrations of cTnT (P<0.001), NT‐proBNP (P<0.001), and CRP (P<0.001) (Table S1). Here, TNNT2 is linked to diabetes mellitus.
