*P < 0.05 vs. normal group. ^§P < 0.05 vs. T2DM with normal RVEF. The Kruskal-Wallis test was used to assess the differences in continuous variables among the three groups. DM, diabetes mellitus; RVEF, right ventricular ejection fraction; PS, peak strain; PSSR, peak systolic strain rate; PDSR, peak diastolic strain rate.
